Product details

200 mA hold, 400 mA trip — the protection window

The Bel Fuse 0ZCJ0020FF2E is a polymeric PTC resettable fuse from the 0ZCJ series, rated for a 200 mA hold current (Ih) and a 400 mA trip current (It) at 30 V max. The 100 ms typical trip time means it clears a sustained overcurrent fast enough to protect downstream wiring and components in low-voltage DC rails. After the fault clears, the PTC resets — the resistance drops from a post-trip maximum of 2.5 Ohms back to the initial 600 mOhms minimum, restoring normal circuit operation without a fuse replacement.

AEC-Q200 and the automotive deployment envelope

This part carries AEC-Q200 qualification, the passive-component stress-test standard for automotive electronics. Combined with cURus and TUV approvals, it is accepted in vehicle cabin and body-control applications where resettable overcurrent protection is specified.

1206 SMD footprint and assembly fit

The concave termination style aids solder wetting inspection.

Frequently asked questions

What is the 0ZCJ0020FF2E's hold current and trip current?

The hold current (Ih) is 200 mA maximum, and the trip current (It) is 400 mA. At 30 V max, the device trips in 100 ms typical when the current exceeds the trip threshold.

What compliance marks does the 0ZCJ0020FF2E carry?

It is qualified to AEC-Q200 and carries cURus and TUV approvals. These marks cover automotive stress testing, North American safety, and European safety standards for resettable fuses.
