Overview
The Bourns MF-RM016/240-2 is a radial leaded polymeric positive temperature coefficient (PPTC) resettable fuse from the Multifuse MF-RM series. Designed for PCB mounting, this component provides overcurrent protection with a maximum rated voltage of 240 VAC and a maximum trip current of 2 A. It features a hold current of 160 mA and a trip current of 370 mA. The device operates within a temperature range of -20°C to +85°C and exhibits an initial resistance of 7.8 ohms. It is available in cut tape or reel packaging.
Feature Summary
- Provides automatic circuit recovery after fault clearance without manual replacement
- Offers dual certification compliance including UL listing and RoHS standards
- Utilizes polymeric technology for consistent thermal response characteristics
Applications
- Overcurrent protection for AC line circuits
- Protection for portable electronic devices
- Industrial instrumentation circuit safeguarding
Procurement Notes
Verify that the specific part number matches the required electrical ratings, particularly the 160 mA hold current and 240 VAC maximum voltage. Confirm the package type corresponds to the project requirements, as the component is available in both cut tape and reel formats. Ensure the supplier documentation confirms RoHS compliance and UL recognition status prior to integration into the design.
Selection Notes
Select this component when designing for AC mains applications requiring resettable protection up to 240 VAC. The 160 mA hold current makes it suitable for low-power signal lines or control circuits where standard fuses would cause unnecessary downtime. Consider the 7.8 ohm initial resistance impact on circuit performance during normal operation. The radial leaded format facilitates easy insertion into through-hole PCB layouts.
Part Context
This part belongs to the Bourns Multifuse MF-RM series, which specializes in PPTC resettable fuses for consumer and industrial electronics. The series offers various current and voltage ratings to accommodate different circuit protection needs. The MF-RM designation indicates a standard polymeric device optimized for general-purpose overcurrent protection in space-constrained applications.
Replacement Considerations
Direct substitutes within the same series include variants with adjusted current ratings such as the MF-RM012/240-2 or MF-RM020/240-2. Cross-brand replacements require matching the 240 VAC rating, 160 mA hold current, and radial leaded package dimensions to ensure mechanical and electrical compatibility.
