Applications
The FEMTOASMDC010F/15-2 is designed for overcurrent protection in portable consumer electronics, wearables, and IoT sensor nodes where board space is critically limited. Its resettable PPTC technology makes it ideal for USB accessories, battery charging circuits, and mobile device subsystems that need automatic recovery from fault conditions without user intervention. The 15 V rating and 100 mA hold current suit low-voltage digital and analog circuits found in compact embedded systems.

Frequently Asked Questions
What are the hold current and voltage ratings of the FEMTOASMDC010F/15-2?
The FEMTOASMDC010F/15-2 has a 100 mA hold current and a 15 V maximum voltage rating. It will trip at approximately 200 mA (2x hold current) at 25°C, providing reliable protection for low-power circuits without nuisance tripping under normal operating loads.
How does the resettable PPTC mechanism of the FEMTOASMDC010F/15-2 behave during a fault?
When a fault current exceeds the trip threshold, the PPTC polymer element heats up and transitions to a high-resistance state, limiting current to a few milliamps within milliseconds. Once the fault is cleared and power is cycled or the device cools to 25°C, the element resets automatically to its low-resistance state, restoring normal circuit operation without replacing the fuse.
Which compact package form factor does the FEMTOASMDC010F/15-2 use, and how does it compare to 0402 components?
The FEMTOASMDC010F/15-2 uses a Femto SMT package measuring 1.8 mm x 1.0 mm x 0.85 mm height, which is slightly larger than a standard 0402 (1.0 mm x 0.5 mm) resistor but accommodates the PPTC polymer stack. It ships on a 7-inch tape-and-reel compatible with standard SMT pick-and-place equipment.
When would a designer choose FEMTOASMDC010F/15-2 over a one-time-blow fuse for USB or battery protection?
A resettable PPTC like the FEMTOASMDC010F/15-2 is preferred when the product cannot easily be serviced in the field, such as sealed wearables or IoT devices. Its automatic recovery at 25°C avoids the need to open the enclosure and replace a blown fuse, reducing warranty returns and extending product life in systems with 5 V to 15 V USB or battery rails.
