Overview
The MPTR30V500 is a Polymeric Positive Temperature Coefficient (PPTC) resettable fuse manufactured by Meritek Electronics. It belongs to the MPTR series and features radial leaded construction for through-hole mounting. The device provides overcurrent protection with a maximum operating voltage range of 16V to 90V and can handle operation currents up to 14.0A. It is designed to function within a temperature range of -40ºC to 125ºC and complies with RoHS standards, being lead-free.
Feature Summary
- Polymeric PTC technology providing automatic reset capability after fault clearance
- Radial leaded package suitable for standard through-hole PCB assembly
- RoHS compliant and lead-free construction for environmental safety
Applications
- Wide variety of electronic applications requiring overcurrent protection
- Consumer electronics circuit protection
- Industrial equipment safeguarding
Procurement Notes
Verify the specific hold current rating associated with the '500' suffix in the official Meritek MPTR Series datasheet, as this value determines the trip threshold. Confirm that the radial leaded form factor matches the target PCB footprint requirements. Ensure the application environment remains within the specified -40ºC to 125ºC operational temperature range for reliable performance.
Selection Notes
Select this component when a resettable overcurrent protection solution is required for circuits operating between 16V and 90V. The radial leaded design is appropriate for high-reliability or legacy through-hole manufacturing processes. Consider the thermal environment, as the device's resistance characteristics vary with ambient temperature within the -40ºC to 125ºC range.
Part Context
This part is a member of the Meritek MPTR series of polymeric PTC devices. The series offers a wide selection of voltage ratings from 16V to 90V and various current ratings up to 14.0A. These components are commonly used as self-resetting fuses in place of traditional one-time fusible links to enhance system maintainability and reduce replacement costs.
Replacement Considerations
Consult the Meritek MPTR Series datasheet for direct substitutes with identical voltage and current ratings. Verify that any alternative PPTC device maintains compatible radial lead spacing and thermal characteristics.
