Token (PWR) Pulse Withstanding Chip Resistors
Provide 50 Percent Increase in Power Dissipation
Preview
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.
To meet the increased demand for the PWR Series resistors, Token has developed a series of pulse withstanding
chip resistors with improved power ratings in reduced surface mounted sizes. Designated the PWR Series, the
chip resistors deliver up to 50 percent higher power ratings than conventional surface mount resistors - up to
1.5W in a standard 2512 size chip.
Token is able to boost this power rating up to 50 percent through a
combination of proprietary power film materials and advanced
manufacturing processes. The PWR Series Resistors are available
in four standard sizes (0805, 1206, 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 meets
restriction of hazardous substances RoHS directive and RoHS
compliance.
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. The PWR Series chip
resistors are specified for use in power supplies, circuit protection devices, portable battery chargers, motor
controls and line-powered equipment.
Token will also produce devices outside these specifications to meet specific customer requirements, please
