ENGINEERING DATA:

RESISTANCE AND TOLERANCES

You can select any ohmic value or

decimal part of an ohm from 0.001W

to 100KW with microhm/microvolt

accuracies to ±0.005% see Fig. 2, p.7.

PRC's unique “single-joint” design on

the four (4) terminal parts makes tab

identification academic.

PROTECTIVE SEAL

Rectangular solvent-resistant epoxy case

offers excellent thermal transfer to base.

For types: HVS1, PRC100T,

PTS1, PVS1 & ST35

4 mm

24 mm (.945”W)

24 mm Tape

8 Pitch

TERMINALS

Solderable “hot-tinned” pure copper

(ETP/OFHC) tab terminals and low

EMF construction reduces thermal effects

usually associated with low value resistors.

For types: HVS2, HVS3, LVS2, L

VS3,

PTS2, PTS3, PVS2, & PVS3
