What are the key electrical ratings?

It features a 60V maximum operating voltage, 0.5A hold current, 1A trip current, and a maximum fault current of 40A.

What should be considered during assembly?

The device is designed for reflow soldering. Exceeding the recommended reflow temperature profile may degrade performance or cause failure.

Is this fuse suitable for continuous fault protection?

No, PPTCs are intended for occasional overcurrent or overtemperature faults and should not be used in applications where repeated or prolonged tripping is expected.

What is the supply status?

The component is currently active and widely available through major distributors.

What should sourcing teams check before buying JK-MSMD050-60V?

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: Low; readiness: easy.

What is the pinout of JK-MSMD050-60V?

Use the JK-MSMD050-60V datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about JK-MSMD050-60V pinout to locate pins, power rails, and interface signals before layout.
