As electronic design engineers have increased the power density of their equipment, the demand for smaller surface mount single-chip circuit protection resistors has also increased. Token developed the PWR series resistors to provide an economical alternative to bulky molded wirewound components or multi-chip solutions while saving both PC board space and manufacturing costs.
Token series of pulse withstanding chip resistors PWR improves power ratings in and reduces surface mounted sizes. Designated the PWR series, the SMD resistors deliver up to 50% higher power ratings than conventional surface mount resistors.
Token is able to boost this power rating up to 50% through a combination of proprietary power film materials and advanced manufacturing processes. The PWR series Resistors are available in four standard sizes (0603, 0805, 1206, 1210, 2010 and 2512) with power ratings from 0.125W to 1.5W, and maximum operating voltage ratings for 100V to 500V. Resistance range is from 10 Ω to 20 MΩ, with tolerance tight to 0.5 percent. The PWR is RoHS compliant. Along with the increased power ratings, the PWR series resistors also feature high surge and high voltage ratings, making them extremely stable in demanding surge and pulse environments.
