PTR030V0185-BK1

Ptc Resettable Fuses Overview

The Eaton PTR030V0185-BK1 is a polymer PTC resettable fuse from the PolyTron series, designed for through-hole radial mounting. It features kinked leads with a 5 mm spacing and operates within a temperature range of -40°C to +85°C. The device maintains a holding current of 1.85 A and trips at 3.7 A under a maximum voltage of 30 V. Initial resistance is typically 30 mOhms, rising to a maximum of 90 mOhms after tripping. It supports a maximum fault current of 40 A and includes cURus and TUV certifications.

Ptc Resettable Fuses Feature Summary

Provides automatic overcurrent protection by increasing resistance when trip conditions are met
Features self-resetting capability upon cooling after fault removal
Includes kinked radial leads for secure PCB mounting

Ptc Resettable Fuses Applications

Overcurrent protection in industrial control circuits
Protection for portable electronic devices
Circuit safeguarding in automotive electronics

Ptc Resettable Fuses Procurement Notes

Verify that the specific BK1 suffix corresponds to the bulk packaging configuration rather than tape-and-reel delivery. Confirm that the component meets RoHS3 compliance standards required for the target assembly. Ensure the thermal environment does not exceed the specified operating limits during normal operation.

Ptc Resettable Fuses Selection Notes

Select this component when a 30 V maximum rating and 1.85 A holding current are required for radial applications. Consider the initial resistance value for low-voltage drop requirements. Evaluate the physical dimensions to ensure compatibility with the available board space and lead spacing constraints.

Ptc Resettable Fuses Part Context

This part belongs to the Eaton PolyTron PTR030V series of polymer PTC devices. These components are engineered for radial lead installation and offer reliable circuit protection without requiring manual replacement after a fault event occurs.
