What are the key ratings for the K2?

It has a rated functioning temperature (Tf) of 115 °C, a holding temperature (Th) of 91 °C, and is rated for 2 A at 250 VAC or 60 VDC.

Is the K2 resettable?

No, the K2 is a non-resettable device. Once the internal fusible alloy melts due to over-temperature, the circuit is permanently opened.

What should be considered during installation?

Avoid excessive mechanical stress on the leads and ensure proper heat sinking during soldering to prevent premature activation.

What is the pinout of K2?

Use the K2 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about K2 pinout to locate pins, power rails, and interface signals before layout.
