What are the primary applications for this device?

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

What should engineers review before using this PTC?

Engineers should review the thermal derating curve, as the hold current decreases at higher ambient temperatures, and ensure the reflow soldering profile does not exceed recommended limits.

What are the key specifications?

Key specs include a 2A hold current, 4A trip current, 16V maximum voltage, 100A maximum fault current, and a maximum trip time of 2 seconds.

What are the sourcing risks?

The device is widely available from distributors like LCSC, but users should ensure the manufacturer's humidity sensitivity (MSL 2) and storage requirements are met to maintain performance.
