600R150-RBZR

Ptc Resettable Fuses Overview

The Littelfuse 600R150-RBZR is a polymeric PTC resettable fuse from the POLY-FUSE 600R series. It features a hold current (Ih) of 150 mA and a trip current (It) of 300 mA. The device is rated for 60 VDC operating voltage with a maximum interrupt rating of 600V Int. It utilizes a rectangular form factor and is designed for through-hole radial mounting. The component provides overcurrent protection by increasing resistance significantly upon fault conditions, resetting automatically once the fault is removed and the device cools.

Ptc Resettable Fuses Feature Summary

• Polymeric positive temperature coefficient construction for automatic reset capability
• Radial leaded package design suitable for through-hole PCB mounting
• Rectangular body shape optimized for compact circuit board layouts

Ptc Resettable Fuses Applications

• Overcurrent protection in low-voltage electronic circuits
• Protection of portable devices and battery-powered equipment
• Circuit safeguarding in consumer electronics assemblies

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix RBZR against the manufacturer's official datasheet to confirm package dimensions and marking details. Ensure the selected variant matches the required hold current and voltage ratings for the target application. Confirm RoHS compliance status and REACH SVHC declarations are current for regulatory adherence. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.

Ptc Resettable Fuses Selection Notes

Select this component when an automatic reset mechanism is preferred over traditional one-time fuses. The 150 mA hold current suits sensitive low-power circuits requiring precise protection thresholds. Consider the 60 VDC rating for compatibility with standard logic and communication lines. Evaluate the thermal environment to ensure the trip time characteristics align with system safety requirements.
