Manchester, New Hampshire (USA) – April 14, 2000 – RCD Components Inc., a leading manufacturer of resistors, coils, and delay lines has announced the release of a cost-effective ‘open-air’ current shunt. This new resistor, designated OA (Open-Air) features non-inductive performance and excellent stability/overload capacity. Available in a wide range of low ohmic resistance’s from 0.001W to 0.1W, and tolerances of 1%, 2%, 3%, 5%, and 10%, and precision temperature coefficients as low as 30ppm, makes this the ideal design for most current shunt applications.

The inherent non-inductive design is ideally suited for current sensing in high speed switching applications including power supplies, snubber, and motor control applications. The efficient thermal design of these resistors allows for cool operation and a smaller footprint than conventional resistors. The OA Series is available in standard power ratings from 1 Watt to 5 Watts and current ratings up to 40 Amps. Units are designed to fit into popular PCB mounting spans of 0.400″, 0.45″, 0.6″, and 0.8″ (intermediate lead spacings from 0.2″ to 1″ are available). Dimensions are 0.190″ max. wide and .30″ to 1.00″ max. high. Special options include a low thermal EMF design, increased current ratings, and stand-offs.

Samples and production quantities of RCD’s OA series are available now, with lead-times of eight weeks for larger orders. Typical pricing is less than $.25 each in production volumes.
