The 0ZCJ0100FF2E lands in a 1206 (3216 Metric) concave package — 3.25 mm x 1.65 mm footprint with a 1.00 mm max thickness. The concave termination profile helps solder fillet formation during reflow, and the surface-mount format suits automated pick-and-place without a manual operation.
Hold current and trip performance
Rated for a 1 A hold current (Ih) at 25 °C ambient, with a trip current (It) of 1.8 A. When the fault current exceeds that threshold, the polymeric element heats and switches to a high-resistance state in typically 300 ms. The resistance jumps from a 55 mOhm initial floor to a 210 mOhm post-trip ceiling — the higher resistance limits the fault current to a safe level until power is cycled.
Automotive-grade qualification
AEC-Q200 qualified, meaning this PTC has passed the stress tests (temperature cycling, moisture resistance, mechanical shock) required for automotive-grade passive components. It also carries cURus and TUV approvals — accepted in North American and European equipment safety schemes.
