Ptc Resettable Fuses datasheet and documents for MF-R090-2-17

MF-R090-2-17

Ptc Resettable Fuses Overview

The Bourns MF-R090-2-17 is a radial leaded, self-resetting PPTC fuse from the MF-R series. It features a 60 VDC maximum voltage rating and a 0.9 A hold current. The device trips at 1.8 A and withstands up to 40 A fault current. Initial resistance is 310 mΩ max. Operating temperature ranges from -40°C to +85°C. Lead spacing is 5.1 mm. Diameter is 11.7 mm.

Ptc Resettable Fuses Feature Summary

Self-resetting polymer positive temperature coefficient (PPTC) technology provides overcurrent protection without manual replacement.
Radial leaded through-hole package facilitates standard PCB mounting in space-constrained layouts.

Ptc Resettable Fuses Applications

Overcurrent protection for automotive circuits
Surge protection for high-reliability electronic equipment
Fault protection for industrial transportation systems

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix '-2-17' against the official Bourns datasheet to confirm exact packaging or tolerance variations. Ensure the component meets RoHS requirements and check for AEC-Q200 automotive qualification if used in vehicle applications. Confirm lead spacing matches the 5.1 mm specification for PCB layout compatibility.

Ptc Resettable Fuses Selection Notes

Select this component when circuit protection requires a resettable solution with a 0.9 A hold current and 60 VDC rating. The radial leaded format is suitable for through-hole assembly where surface mount options are not feasible. Consider the 310 mΩ initial resistance for voltage drop calculations in low-voltage applications.

Ptc Resettable Fuses Part Context

This part belongs to the Bourns Multifuse MF-R series of polymer PTC resettable fuses. These devices offer robust protection against overcurrent conditions by increasing resistance significantly upon heating. The series is designed for cost-effective circuit safeguarding in demanding environments.
