Overview
The Bourns MF-R160-2-17 is a radial leaded PTC resettable fuse from the MF-R series, designed for overcurrent protection in low-voltage circuits. It features a hold current of 1.6 A and a trip current of 3.2 A, with a maximum voltage rating of 30 VDC. The device has a maximum fault current capacity of 40 A and an initial resistance of 105 mΩ. It operates within a temperature range of -40°C to +85°C and utilizes a bulk packaging format.
Feature Summary
- Provides automatic circuit recovery after overcurrent events without manual replacement
- Offers high fault current interruption capability up to 40 A
- Features radial leads for through-hole PCB mounting
Applications
- Low voltage power supply protection
- Consumer electronics circuit safeguarding
- Industrial equipment overload prevention
Procurement Notes
Verify the specific suffix '-2-17' against official Bourns documentation to confirm exact physical dimensions or marking variations. Ensure compatibility with standard through-hole soldering processes. Confirm RoHS compliance status via the latest datasheet revision. Validate that the 30 VDC rating aligns with the target application's peak voltage requirements.
Selection Notes
Select this component when a 1.6 A hold current and 30 VDC maximum voltage are required for radial mounting. Consider the 105 mΩ initial resistance for voltage drop calculations. Evaluate the 40 A max fault current against potential short-circuit scenarios. Ensure the operating temperature range of -40°C to +85°C meets environmental constraints.
Part Context
This part belongs to the Bourns MF-R series of PTC resettable fuses. The series is characterized by radial leaded construction suitable for general-purpose PCB protection. The MF-R160 variant specifically denotes the 1.6 A hold current classification within this family of self-regulating thermal devices.
Replacement Considerations
Publicly confirmed substitute part numbers for MF-R160-2-17 were not identified in available documentation. Verify electrical equivalence if considering alternative manufacturers.
