Telecom Circuit Protector

Description

• The first and most reliable surface mount telecom circuit

protector designed to protect against power cross faults

and comply with all surge requirements.

• Allows compliance with telecom regulatory standards

including Bellcore GR 1089, UL 1950/60950, and FCC part

68. Application circuit testing is recommended.

• Eliminates the need for a current limiting resistor.

• Protects against overcurrent conditions found in telecom tip

and ring applications.

• RoHS Compliant version available (-R option)

after temperature stabilization. Change in resistance from the original value is calculated

and recorded. ∆R<10%.

13.2.4 After 1000 hours is completed, samples are split into two equal lots.

13.2.5 One group is tested to the non-destructive 100% Current Carry Test. After current carry test is

complete, half of the samples are subjected to the Maximum Current Carry Test with the

remaining samples subjected to the Time Current Characteristic Curve Generation.

13.2.6 The other group is tested to the destructive Current Overload Test.

13.3 Moisture Resistance Test:

MIL-STD-202, Method 106E except:

13.3.1 Samples are placed in a temperature/moisture chamber and subjected to 50 cycles.

13.3.2 Temperature and humidity measurements are recorded at 0 cycles, 25 cycles, and 50 cycles.

13.3.3 At the completion of 50 cycles.

Samples are stabilized at 25°C+5°C for a minimum of 15 minutes and a maximum of 24 hours.

The change in resistance from the original value is calculated and recorded. ∆R<10%,

13.3.4 One cycle is:

1) Start at 90-100% RH and 25°+2°C

2) Ramp up to 65°C+2°C within 2 ½ hours

3) Remain at 65°C+2°C for 3 hours

4) Ramp down to 25°C+2C within 2 ½ hours with 80-100% RH

5) Ramp back up to 65°C+2°C within 2 ½ hours with 90-100% RH

6) Remain at 65°C+2°C for 3 hours

7) Ramp down to 25°C+2°C within 2 ½ hours with 80-100% RH

8) Remain at 25°C+2°C for 8 hours with 90-100% RH

13.3.5 Samples are split into two equal lots

13.3.6 One set is tested to the non-destructive 100% Current Carry Test. After completion, the samples

are subjected to the Time Current Characteristic Curve Generation.

13.3.7 The other set is subjected to the destructive Current Overload Test

13.4 Terminal Strength Test:

Downward force is applied to cause a 1mm deflection for 1 minute (no physical evidence of mechanical

or physical damage, change in resistance < 5%)

13.5 Thermal Shock Test:

MIL-STD-202, Method 107D, air-to-air except:

13.5.1 Samples are placed in a temperature chamber and subjected to 200 air-to-air cycles of the

following:

1) Hold -55°C+2°C for 30+5 minutes

2) Transfer to 125°C+2°C within 0.5 minutes

3) Hold 125°C 2°C for 30 5 minutes

4) Transfer to -55°C 2°C within 0.5 minutes

5) Repeat cycle 200 times

13.5.2 At completion of 200 cycles, resistance readings taken after temperature stabilization (25°C 5°C

for 15 minutes minimum to 24 hours maximum)

13.5.3 Samples divided into two equal lots of twenty

13.5.4 One set is tested to the non-destructive 100% current carry test. After completion, the samples

are subjected to the Time Current Characteristic Curve Generation.

13.5.5 The other set is subjected to the destructive Current Overload Test.

13.6 Maximum Current Carry Test

13.6.1 Performed after the non-destructive Load Humidity and 100% Current Carry Tests (same samples

used)

13.6.2 At the completion of the 100% Current Carry Test, the current is increased by 10% of the current

rating of the fuse. Increase occurs every 15 minutes until the fuse opens. Temperature is

monitored constantly.

13.7 Case Resistance Test

EIS/IS-722

13.8 Resistance to Dissolution of Metallization Test

ANSI J-STD-002, Test D

13.9 Mechanical Shock Test

MIL-STD-202, Method 213B, Test Condition A, except:

13.9.1 Test boards mounted to a shock test fixture, which in turn was mounted to the table of the shock

machine.

13.9.2 Shock machine calibrated for the required shock pulse.

13.9.3 Samples subjected to eighteen impacts, three impacts in each of the three mutually

perpendicular axis. Each shock pulse approximated a half-sine wave shape with a magnitude

of 50 g’s for 11 1 milliseconds.

13.9.4 High frequency vibration test is performed after the mechanical shock test is completed.

After the high-frequency vibration test, the samples undergo the 100% current carry test and the

Current overload tests.

machine.

13.10.2 Samples subjected to a simple harmonic motion having an amplitude of 20g peak 20%.

13.10.3 Vibration frequency is varied logarithmically from 10 to 2,000 Hz.

13.10.4 Cycle is performed 12 times in each of the three mutually perpendicular directions.

13.10.5 At the completion of the last cycle, resistance readings are taken after temperature stabilization.

The change in resistance from the original value is calculated and recorded.

13.10.6 After the vibration test is completed, the samples undergo the non-destructive 100% current

carry test and then the destructive Current Overload Test.

13.11 Resistance to Solvents Test

Note:

Due to the similarities of constructions for TCP1.25A and TCP2A, environmental tests were

performed on TCP1.25A only.
