What are the key features of PICOASMDCH010F-2?
- 1.0 A hold current (Ih) with automatic self-resetting PTC overcurrent protection eliminates manual fuse replacement
- Ultra-compact SMT chip package (2.2 mm x 1.5 mm x 0.8 mm) for space-constrained PCB designs
- Surface-mount tape-and-reel packaging supports high-volume automated PCB assembly
What is PICOASMDCH010F-2 used for?
The PICOASMDCH010F-2 resettable PTC fuse protects USB ports, battery charger circuits, and low-voltage power rails from overcurrent and short-circuit events in portable electronics. Its 1.0 A hold current suits lithium-ion battery protection boards, IoT sensor modules, and handheld device power management circuits. The compact SMT chip format allows placement close to the protected load, minimizing trace resistance and ensuring fast response.

Frequently Asked Questions
What hold current does the PICOASMDCH010F-2 support and how does it behave during a fault event?
The PICOASMDCH010F-2 has a 1.0 A hold current, meaning it passes up to 1.0 A continuously without triggering. When current exceeds the trip threshold, the PTC polymer heats up and its resistance rises dramatically to limit current. Once the fault is cleared and the device cools, resistance returns to its low-impedance state, restoring normal circuit operation without replacing the fuse.
How does the compact chip package of PICOASMDCH010F-2 compare to traditional through-hole PTC fuses in tight PCB layouts?
The PICOASMDCH010F-2 measures only 2.2 mm x 1.5 mm x 0.8 mm, significantly smaller than conventional through-hole PTC fuses which typically measure 5 mm or more in diameter. This SMT chip format allows placement within 1 mm of the protected circuit node, reducing parasitic trace inductance and enabling its use in ultra-compact IoT and wearable device PCBs.
Which battery protection or USB circuit designs benefit most from a 1.0 A resettable PTC fuse like PICOASMDCH010F-2?
USB 2.0 host ports rated at 500 mA and single-cell lithium battery protection circuits with charge currents below 1.0 A benefit most from the PICOASMDCH010F-2. The device protects against short circuits and sustained overloads in power bank circuits, Bluetooth modules, and microcontroller power rails operating at 3.3 V or 5 V without requiring manual fuse replacement after each fault event.
How does tape-and-reel packaging of PICOASMDCH010F-2 affect procurement for mass production?
The PICOASMDCH010F-2 is supplied in 7-inch tape-and-reel format (TR, embossed), compatible with standard 8 mm pitch SMT feeders. This packaging allows direct loading into automated pick-and-place machines for high-volume production runs, reducing per-unit handling cost and ensuring consistent placement accuracy for this 2.2 mm x 1.5 mm component.
