Resistor arrays

Vishay has introduced two series of flat chip resistor arrays that integrate four thin film resistors into a single 0612 surface-mount package.

The Beyschlag ACAC 0612 precision series and ACAC 0612 professional series arrays are for applications that demand high component densities and accurate and stable performance.

The arrays feature absolute TCR of ±25 ppm/°K and tracking TCR of ±15 ppm/°K, with tracking TCR of ±10 ppm/°K available. The professional series features absolute TCR of ±50 ppm/°K, with ±25 ppm/°K available. The precision series has absolute tolerance of ±0.25% and matched tolerance of 0.1%, while the professional series has absolute tolerance of ±1%.

Resistance ranges are from 100 ohm to 221 kilohm and arrays are available with four equal values, four different values, or two equal value pairs. Maximum power dissipation for the new arrays is 0.3 W, with individual resistors rated at a maximum of 0.1 W.

The arrays are suitable for use in voltage dividers, feedback circuits and signal conditioning functions. Target applications include automotive engine control units, climate control, transmission controls and driver safety systems, mobile telecom base stations, medical instruments, precision measuring equipment, and high-end audio amplifiers.

The arrays can also be used in sensing and management systems for PSUs and battery chargers.
