Overview
The Bourns MF-RX160 is a radial leaded, self-resetting polymeric positive temperature coefficient (PPTC) device from the Multifuse MF-RX series. Designed for printed circuit board mounting, it provides overcurrent protection with a hold current of 1.6 A and a trip current of 3.2 A. The component operates at a maximum voltage of 60 VDC and features a maximum resistance of 140 mΩ. It is rated for an interrupting capacity of 40 A and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Self-resetting PPTC technology eliminates the need for manual replacement after fault clearance.
- Radial kinked leads facilitate through-hole PCB mounting.
- Provides automatic circuit interruption during overcurrent or overheating events.
Applications
- Overcurrent protection in consumer electronics circuits
- Power supply input protection
- Portable device battery protection
Procurement Notes
Verify availability status as this specific part number may be discontinued or subject to limited distribution. Confirm exact lead style and voltage rating variants against current datasheets before procurement. Ensure compliance with RoHS directives if required by your manufacturing standards. Cross-reference with authorized distributors for accurate stock levels and lifecycle updates.
Selection Notes
Select based on the 1.6 A hold current requirement and 60 VDC operating limit. Ensure the application environment stays within the -40°C to +85°C operational range. Verify that the 140 mΩ maximum resistance does not impact circuit performance. Consider the 40 A interrupting rating for safety margins against potential fault currents.
Part Context
This component belongs to the Bourns Multifuse MF-RX series of resettable fuses. These devices are polymer PTC thermistors designed for circuit protection. The series offers various hold currents and voltage ratings, utilizing radial leads for standard PCB integration. They serve as reusable alternatives to traditional fusible links in electronic assemblies.
Replacement Considerations
Check for direct substitutes such as MF-RX160-72-AP or MF-RX160/72-AP which share similar electrical characteristics but may differ in voltage rating or packaging suffixes. Verify pin compatibility and thermal performance when substituting.
