Resistors provide better surge protection
IRC Advanced Film Division has introduced a series of wire bondable chip resistors.
"The combination of the high surge and high voltage ratings makes the PWC Series a good fit for the most demanding applications, including those involving turn-on surges and lightning pulses", said Gary Bleasdell, Thick Film Business Unit Director for IRC's Advanced Film Division.
"Additionally, the footprint of the resistors is quite small, so they take up minimal board space, providing manufacturers with an excellent alternative to multichip solutions".
The PWC Series resistors are also suitable for portable battery chargers, motor controls and line-powered equipment.
In the 0805, 1206, 2010, and 2512 package sizes, the PWC Series resistors feature power ratings of 125mW, 330mW, 750mW and 1.5W, with maximum voltage ratings of 150, 200, 400 and 500V, respectively.
Resistance range is from 1.0ohm to 10Mohm, with available tolerances from +/-0.5 to +/-5%.
Absolute TCRs are +/-100ppm/C at 10ohm and higher and +/-200ppm/C at less than 10ohm.
Operating temperature range is -55 to +155C.
IRC will also produce devices outside these specifications to meet customer requirements.
Pricing for the PWC 2512 Series resistors is $.39 each in quantities of 5000.
Lead time is stock to 8 weeks.
