What the hold and trip currents mean for your circuit
The 0ZCJ0035FF2G is a polymeric PTC resettable fuse rated for a continuous hold current of 350 mA at 25°C — below that it stays low-resistance and passes normal operation. When the fault current reaches 750 mA, the internal polymer heats and the resistance jumps to a maximum of 1.2 Ohms, limiting the current to protect downstream components. Trip time is 100 ms at the fault condition, which is fast enough to protect most ICs and wiring from overcurrent damage in automotive and industrial control circuits.
Automotive-grade reliability and approvals
Additional approvals from cURus and TUV mean the part is accepted in US and EU regulatory jurisdictions without extra certification work.
Package and board-fit for the 1206 footprint
The concave termination profile aids solder wetting and visual inspection after reflow. Cut Tape works for prototype or low-volume builds.
Sourcing posture for the BOM line
No official second-source or pin-compatible cross-reference from Bel Fuse for this specific 0ZCJ0035FF2G variant. If a second-source is needed, compare the hold current, trip current, and 1206 footprint against other AEC-Q200 PTCs in the same package.
