PLV Series Engineering Attributes:

You can select any value from 1mΩ (milliohm) to 100Ω. Refer to figure 2 for minimum resistance vs. tolerance ratios.
Standard: 0±15 PPM/°C.
Special: 0±10 PPM/°C. When operating from -65°C to +150°C
Full power ratings are based upon ±1% resistance tolerances @ +25°C. Derating is required for closer tolerances, higher temperatures & lower values. Refer to figure 3 shown below.
To ±.001%/year @ +25°C. with no load.
The PLV series features solderable hot-tinned pure copper (ETP/OFHC) wire leads. Higher current-carrying capacity leads from #21 AWG to #8 AWG are available for full power ratings on values below the standard minimum resistance listed.
The PLV series is sealed in high temperature resistant & solvent resistant epoxy. Aluminum cases sealed with epoxy are available for the 7 & 10 Watt sizes.
PRC stamp, type, Ohmic value (Ω) & tolerance, physical size permitting. Custom marking is available upon request.
