Increased ratings available. Multiply by 0.7 for Opt. X APPLICATION NOTES: P/N DESIGNATION: 1. Power Rating: Resistors may be operated up to full rated power with consideration of mounting density, pad & trace geometery, PCB material, and ambient temperature. Standard parts should be derated (W&V) by .67%/°C when ambient exceeds 25°C, low profile parts by 1%/ °C above 70 °C RCD Type Options: X,P,M,L,F,E (leave blank if std) Resis.Code .01%-1%: 3 signif. figures & multiplier, e.g. R010=0.01Ω, R100=0.1Ω, 1R00=1Ω, 1000=100Ω, 1001=1K. Resis.Code 2%-10%: 2 signif. figures & multiplier, R01=0.01Ω, R10=0.1Ω, 1R0=1Ω, 100=10Ω, 101=100Ω, 102=1K. Use extra digits as needed: R005, R0075, R012, etc. 2. Inductance: Standard wound parts are 1 - 20uH typ. For “non-inductive” design, specify Opt.X (0.2uH max ≤50Ω, .37uH >50Ω, 50nH avail). Opt. L (metal plate element) and Opt.M (power film element) are inherently low inductance (1 to 10nH typ). Consult factory for assistance. 3. Pulse Capability: standard MWM (wirewound) and Opt. L (metal plate) offer excellent overload capability greatly exceeding that of film resistors. The overload level can often be economically enhanced by a factor of 50% or more via special processing (Opt.P). Pulse capability is highly dependent on size & resistance (available up to 50 joules). Consult factory for assistance.
