To ensure that we quote the most cost effective model, please complete this questionnaire with as much detail as possible. Indicate the surge level that is applicable to the individual resistor in question. For instance, if the circuit has a 1KV pulse but the resistor will only be subjected to 400V due to source impedance or other resistance in the circuit, then the surge should be listed as 400V.
RCD offers the widest range of surge-tolerant resistors in the industry including wirewound / film / composition models (up to 1 million volts & 30,000 joules!). So if one of our standard models won’t readily meet your requirement, we’ll offer a custom or modified version (we can generally increase the surge capability of standard resistors by 20% to 500% at a fairly low cost via modified construction)…
