Customised wirewound resistors virtually available off-the-shelf
The company’s standard wirewound resistors are offered in various series to meet different performance requirements across a range of body styles. These include precision, axial-leaded parts, such as its 100, SM and PC series devices as well as the high-power axial and aluminium-housed resistors in its UT and UAL series. Surface mount options are also available in its S and SL series of wirewound devices.
The wirewound resistors can be manufactured with great precision, enabling tolerances down to 0.005%. They are extremely stable (15 to 50ppm/year) and operate reliably over extremely wide temperature ranges, from -55 to +350ºC, with temperature coefficients (TCR) as low as 1ppm/ºC. In addition, wirewound resistors can handle high level pulses and transients, and dissipate substantial amounts of power, up to 2.5kW in some instances.
“The relatively simple construction of a wirewound resistor, which has remained unchanged for many years, allows them to be easily customised. Not only can engineers specify exactly what they require, but the manufacturing process also enables us to supply in quantities of hundreds, rather than tens of thousands, if required”, explained Riedon’s VP Engineering, Phil Ebbert.
