RESISTORSCAPACITORSCOILSDELAY LINES ULTRA-LOW OHM, 2 WATT to 20 WATT ULV SERIES RoHS FEATURES Values from 0.002Ω to 0.05Ω, tolerances to ±0.5% Ceramic body results in a fireproof construction Welded construction, low-inductance Excellent overload capability Available on RCD’s exclusive SWIFTTM delivery program! A .041 [1.0] max. ↓ ↑ ↓ Opt. A Stand-offs RCD Type 2 Ultra Low Value, 2-Terminal When ordering low value resistors please note that the lead resistance can be a contributing factor. RCD measures the resistance value at 3/8 ±1/32” from each end of the body (per MIL-R49465). If in actual use, a different span from the resistor body to the PCB will be required, please advise at the time of ordering. .025Ω to 0.05Ω .01Ω to 0.0249Ω .005Ω to 0.0099Ω .002Ω to 0.0049Ω Operating Temp.
