67L125 is a subminiature bimetallic disc thermostat from the Airpax 6700 series, designed to open (break contact) on rising temperature at a nominal 125°C operating point with ±5°C tolerance. This RoHS compliant, positive snap action, single pole/single throw device features gold-plated contacts, a contact resistance of 50 milliohms max, and supports up to 20,000 life cycles at 0.5A/48VDC or 100,000 cycles at gold contact amperage. The thermostat conforms to the TO-220/Y-220 international electronic package standard, weighs approximately 0.5 grams, and offers long-term exposure limits from -55°C to 160°C. Ideal for thermal management applications on power supplies, PC boards, and heat sinks, it provides accurate and reliable temperature sensing and switching for computers, automotive, medical devices, and test equipment.
