2029L/3425L Series

PRODUCT SERVICE

• The 2029L/3425L Series Resettable devices utilize a

unique polymer-based, Positive Temperature Coefficient

(PTC) material to protect electrical circuits against over-

current conditions.

ENVIRONMENTAL SPECIFICATIONS:

Passive Aging: 85°C, 1000 Hours. ±5% typical resistance

change.

Humidity Aging: 85°C, 85% R.H., 1000 hours. ±5% typi-

• In normal operation, the 2029L/3425L Series PTC has

many conductive paths and a very low resistance. In an

overcurrent condition, the temperature of the polymer

material rises. This dramatically reduces the conductive

paths resulting in an immediate rise in resistance. In this

condition, the device provides circuit protection by signif-

icantly limiting the flow of current. However, once the

cause of the initial overcurrent condition is eliminated,

the 2029L/3425L Series PTC cools down and resets to a

low resistance value permitting the normal current flow

to resume.

cal resistance change.

Thermal Shock: 85°C / –40°C, 20 times. ±10% typical

resistance change.

Vibration: MIL-STD 202, Method 201. No resistance

change.

Mechanical Shock: MIL-STD-202, Method 213 test condi-

tion I (100 g’s, 6 sec.). No resistance change.

Max. Surface Temperature: 125°C

Operating/Storage Temperature: –40°C to 85°C

• The 2029L/3425L Series are surface mountable.
