Ptc Resettable Fuses datasheet and documents for SRP175F

SRP175F

Ptc Resettable Fuses Overview

The SRP175F is a PolySwitch resettable PPTC fuse from the SRP series, designed for battery strap applications. It features a hold current of 1.75 A and a trip current of 3.8 A. The device supports a maximum voltage of 15 VDC with a maximum fault current (Imax) of 100 A. Its low resistance is 62 mOhms, and power dissipation is 1.5 W. Dimensions are 23.1 mm length, 3.3 mm width, and 1 mm height. Operating temperature ranges from -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

Qualified to AEC-Q200 automotive standards for reliable performance in demanding environments.
Designed as a battery strap PTC with fast time-to-trip characteristics for rapid circuit protection.
Features low-resistance construction to minimize power loss during normal operation.

Ptc Resettable Fuses Applications

Automotive battery pack overcurrent protection
Electric vehicle (EV) and hybrid electric vehicle (HEV) systems
Portable electronic device battery circuits

Ptc Resettable Fuses Procurement Notes

Verify the specific datasheet revision and AEC-Q200 qualification status before integration. Confirm that the 15 VDC rating aligns with the system's peak voltage requirements. Ensure the 100 A Imax capability exceeds potential short-circuit currents in the application. Check mounting constraints against the specified strap-style dimensions.

Ptc Resettable Fuses Selection Notes

Select the SRP175F when a 1.75 A hold current and 15 VDC rating are required for battery protection. Compare its 62 mOhms resistance against other series options if lower impedance is critical. Consider the AEC-Q200 qualification if the application mandates automotive-grade reliability standards.

Ptc Resettable Fuses Part Context

The SRP175F belongs to Littelfuse's SRP series of PolySwitch resettable fuses. This series is specifically engineered for battery strap applications, offering a compact form factor suitable for space-constrained designs. It complements other Littelfuse circuit protection solutions by providing resettable overcurrent protection with automotive-grade durability.
