Overview
The Bourns MF-RX160/72-AP-14 is a radial leaded, resettable polymer positive temperature coefficient (PPTC) device from the Multifuse RX series. It provides overcurrent protection with a hold current of 1.6 A and a trip current of 3.2 A at a maximum voltage of 72 VDC. The component features a low resistance of 0.09 ohms and a high rated current capacity of 40 A. It operates within a temperature range of -40°C to +85°C and utilizes kinked leads for through-hole PCB mounting.
Feature Summary
- Provides automatic circuit recovery after fault clearance without manual replacement
- Offers robust protection against overcurrent and short circuit conditions in harsh environments
- Eliminates nuisance tripping caused by ambient temperature variations
Applications
- Overcurrent protection for automotive circuits
- Surge and inrush current protection in industrial equipment
- Protection for communication systems and consumer electronics
Procurement Notes
Verify the specific suffix '14' indicates the required kinked lead configuration during procurement. Confirm that the 72V rating aligns with the target circuit's maximum operating voltage. Ensure the 1.6A hold current meets the application's continuous load requirements before finalizing the order.
Selection Notes
Select this component when a radial leaded form factor is required for through-hole assembly. Choose this part if the application demands a 1.6A hold current with a 72VDC maximum voltage rating. Consider the 0.09 ohm resistance for minimal voltage drop impact on sensitive loads.
Part Context
This device belongs to the Bourns Multifuse RX series of polymeric PTC resettable fuses. The series is designed for cost-effective circuit protection in space-constrained layouts. The RX series offers various voltage and current ratings to suit diverse electronic applications across multiple industries.
Replacement Considerations
The part number MF-RX160-72-AP represents the same electrical specifications but may differ in lead style or packaging. Verify mechanical compatibility and lead configuration when substituting with other variants in the MF-RX160/72 family.
