Featured Products
THE VISHAY VALUE
Portfolio Overview
- Power ratings up to 2500 W (20 kW for assemblies) at 25
°C
- Operating conditions up to 450 °C
- High stability, high current, tight tolerance (± 0.05
%)
- Watercooled devices
- Ribwound, roundwire, and oval devices
- Adjustable and non-inductive devices
- Numerous mounting and heatsink options and custom
housing designs
Key Features and Benefits
- Large portfolio offers the "right" solutions for
application requirements
- Meet specific requirements for long life, tight
tolerance, high pulse power, and high operating
temperature
- Superior inductive performance
- Custom assemblies (housing, hardware, mounting)
available to meet space requirements
- Space saving with watercooled
Advantages
- Power requirements over 50 W with high pulse overloads,
high temperature environments, and excellent reliability
requirements (high maintenance costs – fit and forget)
- Mechanically constrained designs (custom housing,
heatsinks, mounting options, etc.)
Market Position
- Largest supplier of resistor technologies in the
market
- Proven source of high-performance wirewound resistors
for power applications and harsh operating conditions
