MICROASMDCH016F-2

Overview

The Littelfuse MICROASMDCH016F-2 is a surface-mount polymer PTC resettable fuse from the microASMD series. It features a 30 VDC maximum voltage rating and a 160 mA hold current. The device trips at 480 mA and offers a maximum fault current rating of 20 A. With a typical resistance of 0.7 ohms and power dissipation of 0.8 W, it operates within a temperature range of -40°C to +125°C in a 1210 package.

Feature Summary

Provides overcurrent protection through automatic thermal reset functionality
Designed for high-temperature automotive applications with robust reliability
Supports surface mount assembly for compact circuit board integration

Applications

Automotive electronics circuit protection
High-temperature industrial control systems
Portable electronic device power lines

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm RoHS compliance status and AEC-Q200 qualification if required for automotive use. Ensure storage conditions respect moisture sensitivity levels prior to reflow soldering to maintain device integrity.

Selection Notes

Select this component when a 30 VDC system requires protection for currents near 160 mA. The 1210 footprint suits space-constrained designs. Verify that the 0.7 ohm initial resistance does not cause excessive voltage drop in the target application circuit during normal operation.

Part Context

This part belongs to the microASMD series of resettable fuses. It complements other variants like the MICROASMD005F-2 and RF5161-000 within the Littelfuse portfolio. The series targets automotive and industrial sectors requiring reliable, self-resetting overcurrent protection solutions.
