Overview
The MF-RHT200-0-17 is a polymeric positive temperature coefficient (PPTC) resettable fuse manufactured by Bourns Inc. This component features a radial leaded package design, suitable for through-hole mounting applications. It is rated for a maximum voltage of 16V and a hold current of 2.0A. The device belongs to the Hi-Temp series, indicating suitability for high-temperature environments. It provides overcurrent protection by increasing resistance significantly when fault conditions occur, automatically resetting once the fault is removed and the device cools down.
Feature Summary
- Polymeric PTC technology for automatic circuit reset after fault clearance
- Radial leaded construction for reliable through-hole PCB integration
- High-temperature capability designed for demanding thermal environments
Applications
- Overcurrent protection in consumer electronics
- Industrial control circuit safeguarding
- Automotive electronic module protection
Procurement Notes
Verify the specific suffix -17 against the official Bourns datasheet to confirm lead form and packaging specifications. Ensure the selected variant matches the required 16V rating and 2.0A hold current for the target application. Confirm RoHS3 compliance status if environmental regulations apply to the manufacturing process.
Selection Notes
Select this component when a resettable fuse with a 16V maximum voltage and 2.0A continuous current capacity is required. The radial leaded format is appropriate for boards utilizing through-hole assembly processes. Consider the high-temperature rating if the operating environment exceeds standard commercial temperature ranges.
Part Context
This part belongs to the MF-RHT series of high-temperature PPTC resettable fuses from Bourns. The series is engineered for robust protection in circuits where standard devices might fail due to thermal stress. The radial leaded configuration distinguishes it from surface-mount alternatives within the broader product family.
Replacement Considerations
Consult the official Bourns replacement guide for direct equivalents. Verify that any substitute maintains the 16V voltage rating and 2.0A hold current while matching the radial leaded package dimensions for mechanical compatibility.
