Overview
The MF-RX135-0-H2 is a polymeric PTC resettable fuse manufactured by Bourns Inc. It features a radial through-hole package with a disc form factor. The component has a maximum voltage rating of 60V and a hold current of 1.35A. It is designed for circuit protection applications requiring resettable overcurrent safeguarding.
Feature Summary
- Polymeric PTC technology provides automatic reset functionality after fault clearance
- Radial leaded disc construction facilitates through-hole mounting on printed circuit boards
- Designed to interrupt excessive current flow while maintaining low resistance during normal operation
Applications
- Overcurrent protection in consumer electronics circuits
- Protection for portable device power inputs
- Circuit safeguarding in industrial control modules
Procurement Notes
Verify the specific suffix H2 against official Bourns documentation to confirm lead-free status and RoHS compliance requirements. Ensure the selected variant matches the required 60V rating and 1.35A hold current specifications for the target application design.
Selection Notes
Select this component when a resettable fuse with a 60V maximum voltage and 1.35A hold current is required. Consider the radial disc package for through-hole assembly needs. Evaluate thermal management requirements as the device dissipates heat during trip conditions, ensuring adequate spacing on the PCB layout.
Part Context
This part belongs to the Multifuse family of polymeric PTC resettable fuses from Bourns. These components serve as self-resetting overcurrent protectors, offering an alternative to traditional one-time fuses. The series is widely used in various electronic industries for reliable circuit protection without manual replacement.
Replacement Considerations
Equivalent parts include the MF-RX135/72-AP and MF-RX135/72 variants, which share similar electrical characteristics but may differ in voltage ratings or packaging details. Verify exact specifications before substitution.
