What are the primary applications?

It is used in computers, mobile phones, automotive controls, and battery-powered portable electronics.

How does the PTC function?

The device increases its resistance significantly when current exceeds the trip threshold, effectively limiting current flow until the fault is removed and the device cools.

What are the key electrical ratings?

It features a 500mA hold current, 1A trip current, and a maximum voltage rating of 60V.

Are there specific mounting requirements?

Yes, it is designed for SMT reflow soldering. Hand soldering is discouraged, and soldering iron contact should be limited to 3 seconds at temperatures below 350°C.

What should sourcing teams check before buying BSMD1812-050-60V?

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

What is the pinout of BSMD1812-050-60V?

Use the BSMD1812-050-60V datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about BSMD1812-050-60V pinout to locate pins, power rails, and interface signals before layout.
