The device handles steady state current up to 3A with a maximum received energy rating of 17J. The device features a dissipation constant of 11mW/°C and can handle a body temperature of 151°C at 100% of its maximum current rating. Maximum capacitance at the device’s 277V voltage rating is 200μF. The SL10 10003 provides a more compact alternative to larger NTC devices or the more expensive combination of a power resistor, relay and timer or implementation of the same functionality with active circuits.
Eric Rauch, President and CEO, Ametherm, comments: “The SL10 10003 thermistor is the simplest and most cost-effective way to limit inrush current in LED driver and ballast circuits, as well as in PFC circuits. It’s a unique made-in-USA, UL-approved way for designers to get the 277V headroom they need for more reliable LED lighting circuitry and for power supplies with ratings under 500W.”
Samples and production quantities of the SL10 10003 are available now, with factory lead times of four to five weeks.
