PICOASMDC020S-2

Ptc Resettable Fuses Overview

The Littelfuse PICOASMDC020S-2 is a surface-mount PolySwitch resettable fuse designed for automotive applications. It belongs to the picoASMDC series, certified to AEC-Q200 standards for high-temperature reliability. The device features a 0805 (2012 metric) package with dimensions of 2.10mm x 1.40mm and a maximum height of 0.68mm. Key electrical parameters include a hold current (Ih) of 200mA, a trip current (It) of 400mA, and a maximum voltage rating of 15VDC. The initial resistance is typically 3.2 Ohms, with a maximum fault current rating of 20A.

Ptc Resettable Fuses Feature Summary

• Provides overcurrent protection in extreme automotive environments without requiring replacement after fault conditions.
• Automatically resets to normal operation once power is removed or the overcurrent condition ceases.
• Complies with AEC-Q200 qualification standards for automotive-grade reliability.

Ptc Resettable Fuses Applications

• Overcurrent protection for sensitive circuits in automotive electronic control units.
• Protection for battery-powered systems and handheld electronics in vehicle interiors.

Ptc Resettable Fuses Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or direct channels. Confirm that the specific suffix '-2' matches the required packaging configuration for your assembly line. Ensure compliance with RoHS3 specifications and check moisture sensitivity levels prior to storage and reflow soldering processes.

Ptc Resettable Fuses Selection Notes

Select this component when circuit protection is required for low-voltage automotive lines operating at 15VDC. The 0805 footprint suits space-constrained PCB layouts. Ensure the application current remains below the 200mA hold threshold while accounting for ambient temperature derating curves provided in the official datasheet to prevent nuisance tripping.

Ptc Resettable Fuses Part Context

This part is part of the picoASMDC series, which offers compact surface-mount solutions compared to larger ASMD packages. It utilizes polymer positive temperature coefficient technology to provide resettable protection. The series is engineered specifically for harsh automotive environments, offering higher hold currents and voltages than previous generations in smaller form factors.
