Fullerton, Calif. A new series of precision thinfilm resistor networks from TT Electronics BI Technologies features an expanded resistance value range, four package styles and tighter resistance tolerance, giving design engineers more options to create precision voltage dividers and set accurate amplifier gains in a variety of applications including test and measurement devices, commercial avionics and medical equipment or devices. They also find homes in instrumentation amplifiers, measurement bridge circuitry, data converters and precision analog circuits.
Constructed with nichrome resistors on ceramic substrates for excellent resistive properties, the precision resistor networks are available in QSOP, SOIC, PDIP and BGA packages. The nichrome resistive element is protected from moisture by a proprietary passivation material, said the company.
The resistor networks offer an expanded range of resistance values from 10Ω to 1 MΩ and provide excellent resistor precision and accuracy with resistor tolerances to ±0.025% and resistor ratio tracking tolerances to ±0.01%. They also offer absolute temperature coefficient of resistance (TCR) values to ±25 ppm/°C with TCR tracking to ±1 ppm/°C, providing excellent performance over the military temperature range. Package leads are available with a matte tin finish for RoHS-compliant resistor networks and tin/lead (SnPb) finishes for military applications.
The networks are available in standard isolated, bussed, ladder networks and voltage divider circuit configurations. The thinfilm resistor networks also can be designed with custom schematics, and are available for use in hybrid microcircuits as ceramic substrates and wire bondable chips.
Typical pricing for the precision thinfilm resistor networks starts at $0.80. Delivery is from stock to six weeks, with minimum order quantities at 500 pieces.
