Any value available within resistance range

Foil power resistors offer the best

Vishay Bulk

approach to low value power and current sensing when a

combination of accuracy, tight TCR, low thermal EMF, low

voltage coefficient, Kelvin connection, and long term stability

(under power) are required.

Vishay Models VHP-3 and VHP-4 offer all welded

construction and screw mounting directly to a metal heat sink

for maximum heat transfer. Hermetic sealing and nitrogen

back fill provide the maximum protection against

environmental stresses, thereby ensuring long term stability.

A special feature of this construction is Kovar eyelet’s and

OFHC solder plated copper leads providing the lowest

thermal EMFs in the industry.

Vishay Model VPR247 has many of the advantages of the

VHP-4 but with significantly reduced size and weight. It also

has gold plated copper leads.

Our Application Engineering department is available to

advise and to make recommendations. For non-standard

technical requirements and special applications, please
