Notes
1. Upper end of resistance range varies with model selected (i.e. VHP202Z; the range is to 100 kΩ; VHA518-10Z, the range is to 1.0 MΩ) per
Table 2
2. Not to exceed power rating of resistor
3. Insulating sleeve - a special case insulating plastic sleeve is available on VHAZ models - specify letter “P” as a suffix to model number
(i.e. VHA412ZP)
4. 0.200" (5.08 mm) lead spacing available - specify VHP202ZJ
5. Inductance (L) due mainly to the leads
6. The resolution limit of existing test equipment (within measurement capability of the equipment, or “essentially zero”)
7. µV/° relates to EMF due to lead temperature difference and µV/watt due to power applied to the resistor
8. Load life ΔR max. can be reduced through in-house oriented processes
