What are the key electrical ratings?

It features a 30V maximum voltage, 0.2A hold current, 0.46A trip current, and a maximum interrupt current of 40A.

What should be considered during PCB design?

Ensure the device is not placed in a restricted space where thermal expansion could be constrained, and follow the recommended solder pad layout.

Is this device suitable for high-inductance circuits?

Caution is advised; large inductances can generate voltage spikes (L di/dt) that may exceed the 30V rating of the PPTC.

What should sourcing teams check before buying JK-NSMD020-30V?

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

What is the pinout of JK-NSMD020-30V?

Use the JK-NSMD020-30V datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about JK-NSMD020-30V pinout to locate pins, power rails, and interface signals before layout.
