PTC resettable fuse for overcurrent protection on dense PCBs
The 1206L010/30WR is a polymeric positive-temperature-coefficient (PTC) resettable fuse — it protects a circuit by switching to a high-resistance state when the current exceeds its trip threshold, then resets automatically when power is removed and the device cools. Rated for a hold current of 100 mA at 30 V max, it trips at 250 mA within 1.5 s typical, limiting fault current to 10 A maximum.
AEC-Q200 qualification and regulatory approvals
Approved by cURus (North America) and TUV (Europe), so the same BOM line passes safety certification in both jurisdictions without a part change.
