■ Recommended Soldering Conditions
Recommendations and precautions are described below.
Recommended soldering conditions for reflow
●
·Reflow soldering shall be performed a maximum of
two times.
·Please contact us for additional information when
used in conditions other than those specified.
·Please measure the temperature of the terminals and
study every kind of solder and printed circuit board
for solderability before actual use.
For soldering (Example : Sn/Pb)
Temperature
140 °C to 160 °C
Above 200 °C
235 5 °C
Time

Peak
60 s to120 s
30 s to 40 s
max. 10 s
For lead-free soldering (Example : Sn/Ag/Cu)
Peak
Temperature
150 °C to 180 °C
Above 230 °C
max. 260 °C

This product has circuits on both sides. Therefore, do not use
adhesives because they may impair the products characteristics.
Time
Flow Soldering
●
We do not recommend flow soldering to the product, because solder bridging may occur due to the
narrow pitch of the terminals and the characteristics of the product may be badly affected when using
adhesive to affix it to a circuit board.
Safety Precautions
The following are precautions for individual products. Please also refer to the precautions common to EMI Filters,
Fuses, and Sensors(MR Elements) shown on page EX2 of this catalog.
1. Take measures against mechanical stress during and after mounting of Chip RC Networks (hereafter called the RC networks)
so as not to damage their electrodes and protective coatings.
Be careful not to misplace the RC networks on the land patterns. Otherwise, solder bridging may occur.
2. Do not use halogen-based or other high-activity flux. Otherwise, the residue may impair the RC networks' performance
and/or reliability.
3. Perform sufficient preheating so that the difference of the solder temperature and the RC networks chip surface
°
°
temperature becomes 100 C or less. Maintain the temperature difference within 100 C during rapid cooling by
immersion into solvent after soldering.
4. When soldering with a soldering iron, never touch the RC networks' bodies with the tip of the soldering iron. When
using a soldering iron with a high temperature tip, finish soldering as quickly as possible (within three seconds at
°
350 C max.).
5. As the amount of applied solder becomes larger, the mechanical stress applied to the RC networks increases, causing
problems such as cracks and faulty characteristics. Avoid applying an excessive amounts of solder.
6. Do not apply shock to the RC networks or pinch them with a hard tool (e.g. pliers and tweezers). Otherwise, the RC networks'
protective coatings and bodies may be chipped, affecting their performance.
7. Avoid excessive bending of printed circuit boards in order to protect the RC networks from abnormal stress.
8. The static capacitance may decrease by a few percent from the time of shipment due to the characteristics peculiar to
dielectric materials having a high dielectric constant.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.

Safety Precautions (Common precautions for EMI Filters, Fuses, and Sensors[MR Elements])
• When using our products, no matter what sort of equipment they might be used for, be sure to make a written
agreement on the specifications with us in advance. The design and specifications in this catalog are subject
to change without prior notice.
• Do not use the products beyond the specifications described in this catalog.
• This catalog explains the quality and performance of the products as individual components. Before use, check
and evaluate their operations when installed in your products.
• Install the following systems for a failsafe design to ensure safety if these products are to be used in equipment
where a defect in these products may cause the loss of human life or other significant damage, such as damage to
vehicles (automobile, train, vessel), traffic lights, medical equipment, aerospace equipment, electric heating
appliances, combustion/gas equipment, rotating equipment, and disaster/crime prevention equipment.
Systems equipped with a protection circuit and a protection device
Systems equipped with a redundant circuit or other system to prevent an unsafe status in the event of a single fault
✽
✽
(1) Precautions for use
• These products are designed and manufactured for general and standard use in general electronic equipment
(e.g. AV equipment, home electric appliances, office equipment, information and communication equipment)
• These products are not intended for use in the following special conditions. Before using the products,
carefully check the effects on their quality and performance, and determine whether or not they can be used.
1. In liquid, such as water, oil, chemicals, or organic solvent
2. In direct sunlight, outdoors, or in dust
3. In salty air or air with a high concentration of corrosive gas, such as Cl , H S, NH , SO , or NO
4. Electric Static Discharge (ESD) Environment
2
2
3
2
2
These components are sensitive to static electricity and can be damaged under static shock (ESD).
Please take measures to avoid any of these environments.
Smaller components are more sensitive to ESD environment.
5. Electromagnetic Environment
Avoid any environment where strong electromagnetic waves exist.
6. In an environment where these products cause dew condensation
7. Sealing or coating of these products or a printed circuit board on which these products are mounted, with
resin or other materials
• These products generate Joule heat when energized. Carefully position these products so that their heat will
not affect the other components.
• Carefully position these products so that their temperatures will not exceed the category temperature range due
to the effects of neighboring heat-generating components. Do not mount or place heat-generating components
or inflammables, such as vinyl-coated wires, near these products (except Thermal Cutoffs).
• Note that non-cleaning solder, halogen-based highly active flux, or water-soluble flux may deteriorate the
performance or reliability of the products.
• Carefully select a flux cleaning agent for use after soldering. An unsuitable agent may deteriorate the performance
or reliability. In particular, when using water or a water-soluble cleaning agent, be careful not to leave water
residues. Otherwise, the insulation performance may be deteriorated.
(2) Precautions for storage
The performance of these products, including the solderability, is guaranteed for a year from the date of arrival
at your company, provided that they remain packed as they were when delivered and stored at a temperature
of 5 °C to 35 °C and a relative humidity of 45 % to 85 %. (Micro Chip Fuses: Guaranteed for 6 months from the
date of arrival at your company)
The performance of EMI Filters is guaranteed for 6 months or a year from the outgoing inspection date indicated on
the packages, provided that they are stored at a temperature of -5 °C to +40 °C and a relative humidity of 40 %
to 60 %. Check the guarantee period in the specifications. The performance of Thermal Cutoffs is guaranteed for a
year from the outgoing inspection date indicated on the packages, provided that they are stored at a temperature of
-10 °C to +40 °C and a relative humidity of 30 % to 75 %.
Even within the above guarantee periods, do not store these products in the following conditions. Otherwise,
their electrical performance and/or solderability may be deteriorated, and the packaging materials (e.g. taping
materials) may be deformed or deteriorated, resulting in mounting failures.
