Resettable PTCs

Surface Mount PTC

3425L Series

• The 3425L Series Resettable devices utilize a unique polymer-based,

Positive Temperature Coefficient (PTC) material to protect electrical

circuits against overcurrent conditions.

ENVIRONMENTAL SPECIFICATIONS:

Passive Aging: 85°C, 1000 Hours.

Humidity Aging: 85°C, 85% R.H., 100 hours.

• In normal operation, the 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 significantly limiting the flow of

current. However, once the cause of the initial overcurrent condition is

eliminated, the 3425L Series PTC cools down and resets to a low

resistance value permitting the normal current flow to resume.

Thermal Shock: 85°C / –40°C, 20 times.

125°C / –55°C, 10 times.

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

Mechanical Shock: MIL-STD-202, Method 213 test condition I

(100 g’s, 6 sec.).

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

remain in sealed bags prior to use.

• The 3425L Series are surface mountable.

AGENCY APPROVALS: Recognized under the Components Program

of Underwriters Laboratory and the Component Acceptance Program of

CSA. TUV approved.
