Whether it is for <strong><em>magnetic resonance scanners<\/em><\/strong>, <strong><em>aircraft flight controls<\/em><\/strong> or <em><strong>down-hole instrumentation for oil wells<\/strong><\/em>, Riedon\u2019s advanced <strong>CHR and HVS chip<\/strong> resistor technology delivers high-performance, high-temperature operation with resistance values up to 10T\u03a9.<\/p>\n<p>The maximum continuous working temperature of standard components with nickel\/tin terminals is usually specified as +155oC (tin has a peak temperature of 230oC while nickel is limited to 160oC). By using superior materials, and combining an inner terminal of silver\/palladium with a wrap-around of platinum\/silver, Riedon is able to offer chip resistors that can work in applications up to 300oC. This special termination technology confers several other advantages for demanding applications. In particular it is suitable for silver epoxy attachment, which provides the reliability and high temperature performance essential for the <strong>temperature probes and pressure monitoring device<\/strong>s used in<strong> oil and gas exploration<\/strong>.<\/p>\n<p>Further, by avoiding nickel, these chip resistors are completely non-magnetic and can be used in the presence of strong magnetic fields, such as medical CT and MRI scanners. Similarly, no tin avoids the \u2018tin-whisker\u2019 problem that can be a concern in aerospace applications. Termination material also influences VCR (voltage coefficient of resistance), an important characteristic of high voltage resistors.<\/p>\n<p>Riedon\u2019s chip resistors are specifically designed to achieve low VCR. The CHR series of non-magnetic chip resistor provides resistance values from 1 Ohm to 10M\u03a9 with power ratings from 0.05W to 1.5W, depending on package size (from 0402 to 4020). Various resistance tolerances are available, from as low as \u00b10.5%, along with TCRs (temperature coefficient of resistance) specified from \u00b150ppm\/oC. The standard temperature range is -55oC to +155oC with the HT version extending to +300 oC. Riedon\u2019s HVS series of high-voltage, high-temperature, thick film chip resistors addresses requirements for higher value resistors, from 100k\u03a9 to 10T\u03a9, with operation up to 6000V. Again, power-rating options are available up to 1.5W with an HT version provides high temperature operation up to +300 oC. VCR is also specified across the range, starting from as low as 10ppm\/V. <strong><span style=\"color: #ff6600;\"><em>\u201cHigh value resistors, up to 10 Tera-Ohms, are a core competency for Riedon\u201d<\/em><\/span><\/strong>, said Phil Ebbert, their VP of Engineering, <strong><em><span style=\"color: #ff6600;\">\u201cSome other manufacturers only deliver up to 10M\u03a9. This, combined with our ability to achieve high precision and stability over a wide temperature range, is what distinguishes these Riedon products.\u201d<\/span><\/em><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Riedon, a specialist manufacturer and supplier of cutting-edge, resistive solutions, enables electronic equipment designs capable of meeting the demanding requirements of medical and aerospace applications and operating in the extreme environments encountered in the oil and gas industries.
