Thin Film Resistor Network MODELS 16XX, 1NXXXX, 1SXXXX1 · · · Custom circuits Thin film resistor network RoHS compliant Applications Instrumentation Amplifiers Precision Voltage Dividers Measurement Bridge Circuitry Converter Applications Precision Analog Circuits Ladder Networks · · · · · · Specifications BI Technologies provides customized thin film resistor networks in any of our standard molded packages. The networks can include uncommon values, tolerances and interconnection between the resistors. Custom thin film resistor networks offer many advantages. Starting with the choice of resistance values, design engineers can mix and match values according to their requirements. Ratio tolerances between resistors and TCR tracking are superior to alternative technologies including foil resistors. With up to twenty five resistors, these networks are housed in popular JEDEC standard packages. These low cost high reliability packages allow users a convenient means for incorporating these custom networks into circuits and products. Schematics for these networks are usually limited by package terminal count only. These networks are ideal for use in critical and demanding applications. Our networks are tested to military and industrial test requirements associated with high performance resistors. Features Precision Nichrome Resistors on Ceramic or Silicon Substrates.
