PAD LAYOUT
Exceptional perfomance and reliability is
achieved via highest grade materials and
processing. An all-welded wirewound construction is standard,
featuring premium-grade wire for superior stability and surge
capability. Opt. L low profile models feature a non-inductive metal
plate element. The power film version (Opt.M) achieves values as high
as 1MΩ and is inherently low inductance thereby enabling stable
operation at high frequencies.

APPLICATION NOTES:
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
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.
