01 of 02 version 2010 preview following market demands, token electronics provided an extent of bulk ceramic composition rmca, rmcb series to rmcc series. the cap and lead assemblies are pressed onto the rmcc resistor core, fnishing the resistor and providing rugged terminal attachment. token surge resistors - rmcc series are primarily designed for high voltage, power charging/discharging circuits,, surge energy applications and conform to the rohs directive and lead-free. for customed designs, tighter tolerances, non-standard technical requirements, or custom special applications, please contact our sales for more information. bulk ceramic construction : ? bulk metal ceramic resistors that consists of a clay, alumina, and ceramic fller that has been blended and pressurized into a resistive core and then covered with a molded outer insulating core. replacement carbon-composition resistors : ? design requirements for custom sizes, surface mount, or special footprints can be met easily. ? in cases where several carbon-composition resistors have been used together in an array to achieve a particular rating, they have been replaced with a single bulk ceramic resistor, frequently at a lower installed cost. rmcc surge metal ceramic resistors (rmcc) the way allows energy and power to be uniformly distributed surge metal ceramic resistors features - operating temperature -40c ~ 155c. - resistance tolerance k(10%), m(20%). - typical resistance range 470 ohm ~ 100 kohm. - replaces 1 and 2 watt carbon composition resistors. - suitable for noise suppressor of engine ignition system. - high peak power, reliable with non-disconnection failure. - rated wattage up 5w, meets high energy density demands. applications - radar, motor drives, broadcast transmitters, - x-ray, lasers, medical defbrillators, - dynamic braking, soft-start/current-limit, - snubber circuits, dummy loads, energy research - rf amplifers, semiconductor process, power conditioning http://www.token.com.tw/ rfq token.com.tw t oke n
