RS Components (RS) has introduced the Isabellenh\u00fctte portfolio of high-precision, low-ohmic current-sense resistors.\u00a0<\/p>\n\n\n\n
Produced using two different proprietary manufacturing technologies known as ISA-Plan and ISA-Weld, Isabellenh\u00fctte\u2019s current-sense resistors meet stringent criteria with regard to thermoelectric voltage, long-term stability and inductance that allow electronics designers to optimise power use on PCBs more efficiently than otherwise possible.<\/p>\n\n\n\n
Isabellenh\u00fctte is one of the world’s leading suppliers of high-quality low-ohmic power resistors. RS is the first high-service-level distributor to offer Isabellenh\u00fctte products, including over 200 SMD power resistor specifications.<\/p>\n\n\n\n
Isabellenh\u00fctte power resistors are widely used in automotive (https:\/\/uk.rs-online.com\/web\/c\/passive-components\/fixed-resistors\/surface-mount-fixed-resistors\/?applied-dimensions=4291286111) such as battery management in electric, hybrid and conventional vehicles, ABS (anti-lock braking systems), ASR (anti-slip regulation), cruise control, power steering, fuel injection and traction control systems. They are also found in power supplies, as shunts for energy meters and IGBT (insulated-gate bipolar transistor) power modules, and in various industrial, telecommunications and consumer applications.<\/p>\n\n\n\n
In ISA-Plan devices, highly precise resistor elements are etched onto a homogenous film of one of Isabellenh\u00fctte\u2019s resistance alloys \u2014 either Manganin or Zeranin \u2014 which exhibit a very low temperature coefficient of resistance (TCR). They are electrically insulated, mounted on a metal substrate with good thermal conductivity, and packaged as small SMDs. <\/p>\n\n\n\n
The resistor material is thermoelectrically well matched to copper, reducing thermoelectric voltage to virtually zero. Heat conduction into the substrate permits excellent pulse power ratings. <\/p>\n\n\n\n
ISA-Plan resistors are available with resistance values from 1m\u03a9 to 4.7\u03a9, tolerances of 0.5%, 1% or 5%, power ratings from 0.5W to 7W, and TCR down to 20ppm\/\u00b0C.<\/p>\n\n\n\n
ISA-Weld power resistors consist of an electron-beam-welded composite of copper and a resistance alloy: Manganin, Zeranin, Noventin, ISAOHM or Aluchrom. These materials are flexible enough to be adapted to a range of geometries and applications and offer uniform current density and heat distribution within the resistor. ISA-Weld resistors offer resistance values from 0.1m\u03a9 to 6.8m\u03a9, tolerances of 1% or 5%, power ratings up to 15W, and TCR down to 20ppm\/\u00b0C.<\/p>\n\n\n\n
The Isabellenh\u00fctte portfolio of high-precision, low-ohmic current-sense resistors is shipping now from RS in the EMEA and Asia Pacific regions.<\/p>\n","protected":false},"excerpt":{"rendered":"
