Overview
The Meritek MPRV240V040 is a polymeric PTC resettable fuse designed for through-hole radial mounting. It features a disc package with a lead spacing of 0.201 inches (5.10 mm). The component has a voltage rating of 240 V and a hold current (Ih) of 400 mA. Its maximum current rating is 5.5 A, with a trip time of 24 seconds under specified conditions.
Feature Summary
- Polymeric PTC technology provides automatic circuit protection that resets after fault clearance.
Applications
- Overcurrent protection in electronic circuits
Procurement Notes
Verify the specific datasheet revision and electrical characteristics against official Meritek documentation before integration. Confirm that the radial lead configuration and disc package dimensions align with the target PCB footprint requirements to ensure proper mechanical fit and thermal performance during operation.
Selection Notes
Select this component when a resettable overcurrent protection solution is required for low-current applications up to 400 mA. Ensure the operating environment does not exceed the 240 V rating and that the 5.5 A maximum current capability accommodates potential surge currents without nuisance tripping during normal operation cycles.
Part Context
This part belongs to the Meritek MPRV Series of polymeric PTC resettable fuses. These devices are manufactured by Meritek Electronics Corporation, a producer of advanced circuit protection devices and passive components. The series utilizes polymer technology to provide reliable protection in various electronic systems.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative PTC fuses based on matching voltage, hold current, and package specifications from official manufacturer cross-reference lists.
