High power applications requiring resistors with power ratings above 1W can be challenging. For ceramic based chip resistors, this generally requires chip sizes of 2010 or larger which are susceptible to cracking and solder joint failure.  

Stackpole’s SM Series of surface mount molded wirewounds offer power ratings from 2W to 4W with compliant terminations that eliminate these issues. In addition, the SM series wirewound elements provide superior pulse and overload handling compared to film-based chip resistors.

The robust electrical and environmental performance of the SM series is ideal for industrial applications, machine automation and control, power supply and motor control, traffic control, as well as safety and security systems. 

Pricing for the SM depends on size, value, and tolerance. Contact Stackpole or one of our franchised distribution partners for specific or volume pricing.
