Ptc Resettable Fuses datasheet and documents for NANOASMDCH020F-2

NANOASMDCH020F-2

Ptc Resettable Fuses Overview

The Littelfuse NANOASMDCH020F-2 is a PolySwitch nanoASMD series resettable PPTC fuse designed for surface mount applications. It features a hold current of 200 mA and a trip current of 420 mA, with a maximum voltage rating of 24 VDC. The device offers a maximum interrupting rating of 100 A and an initial resistance of 650 mOhms, rising to a maximum post-trip resistance of 3.1 Ohms. Packaged in a 1206 (3216 metric) footprint with a height of 0.82 mm, it operates within a temperature range of -40°C to +85°C and holds AEC-Q200 automotive qualification.

Ptc Resettable Fuses Feature Summary

Provides overcurrent protection through automatic circuit interruption upon thermal activation
Reverts to low-resistance state after fault removal and cooling
Complies with AEC-Q200 automotive component qualification standards

Ptc Resettable Fuses Applications

Automotive electronic circuits requiring AEC-Q200 compliance
Battery charger protection
AC-DC and DC-DC power converter input stages
Electronic ballast circuits

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix designation against the manufacturer datasheet to confirm exact electrical tolerances and package variations. Confirm AEC-Q200 certification status directly from official Littelfuse documentation prior to integration into automotive designs. Ensure storage conditions account for moisture sensitivity levels specified in the data sheet.

Ptc Resettable Fuses Selection Notes

Select this component when a compact 1206 footprint is required for 24V automotive systems. Compare the 650 mOhms initial resistance against load requirements to minimize voltage drop. Evaluate the 100A interrupting capacity against potential short-circuit currents in the target application to ensure adequate safety margins.

Ptc Resettable Fuses Part Context

This part belongs to the nanoASMD family of resettable fuses, which are engineered for high-density surface mount layouts. The series utilizes polymer positive temperature coefficient technology to provide reusable overcurrent protection. It serves as a compact alternative to traditional axial lead fuses in space-constrained PCB designs.
