Overview
The Bourns MF-RX160-2-99 is a polymeric positive temperature coefficient (PPTC) resettable fuse designed for overcurrent protection in electronic circuits. It features a hold current of 1.6 A and a trip current of 3.2 A, with a maximum voltage rating of 60 V DC. The device exhibits a typical resistance of 0.09 ohms and utilizes a radial through-hole package configuration.
Feature Summary
- Provides automatic circuit interruption upon detection of excessive current flow
- Restores normal conductivity after the fault condition is removed and the device cools down
- Offers repeated protection cycles without requiring manual replacement or component disposal
Applications
- Overcurrent protection for portable computing devices and peripherals
- Surge protection in telecommunications equipment and network interfaces
- Circuit safeguarding within industrial control systems and instrumentation
Procurement Notes
Verify that the specific suffix '99' corresponds to the required packaging format and compliance status as defined in the official manufacturer datasheet. Confirm that the electrical ratings align with the target circuit's operational requirements before finalizing procurement orders.
Selection Notes
Select this component when a resettable protection mechanism is preferred over traditional one-time fuses. Ensure the application environment supports the thermal cycling necessary for the PPTC material to recover its low-resistance state after tripping events occur during operation.
Part Context
This part belongs to the Multifuse RX series of polymeric resettable fuses manufactured by Bourns Inc. The series is engineered to provide reliable thermal protection across various consumer, industrial, and communication electronics markets.
Replacement Considerations
Potential substitutes include other Bourns Multifuse RX series variants with matching hold and trip currents. Cross-reference alternative manufacturers offering equivalent PPTC specifications if supply constraints exist.
