RCD Type
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
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.
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.
Use extra digits as needed: R005, R0075, R012, etc.
Tolerance Code: K=10%, J=5%, H=3%, G=2%, F=1%,
D=0.5%, C=0.25%, B=0.1%, A=0.05%, Q=0.02%, T=0.01%
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.
Packaging: B = Bulk, T = Tape & Reel
TC (leave blank if standard): 5 = 5ppm, 10 = 10ppm, 20=20ppm,
30=30ppm,50=50ppm, 101=100ppm, 201=200ppm, 301=300ppm
Termination: W= Lead-free, Q= Tin/Lead. Leave blank if either is
acceptable (RCD will select based on lowest price and quickest delivery).
