VPG Alpha Electronics RWA/RWB/RWC Precision Bulk Metal® Foil Resistors

VPG Alpha Electronics RWA/RWB/RWC Precision Bulk Metal® Foil Resistors are available in 0603, 0805, and 1206 SMD packages size with a 22V to 95V maximum voltage range. These ultra-precision wraparound resistors offer a 5Ω to 30kΩ resistance range in a wide operating temperature range (-65°C to +155°C). Other features include a primary resistance element consisting of special alloy foil several µm thick. The RWA/RWB/RWC components are ideal for use as precise amplifier circuitry and referential power supplies in items such as sophisticated electronic equipment, instrumentation, and medical electronic apparatus.
