ORNTA2002AT3

ORNTA2002AT3 Description

The ORNTA2002AT3 from Vishay is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 4-resistor array features a 20 kΩ resistance value per element with an ultra-tight ±0.1% tolerance and a low ±25 ppm/°C temperature coefficient, ensuring exceptional stability across a wide operating temperature range (-70°C to +150°C derated, up to +125°C at full power). Housed in an 8-pin SOIC (Molded Epoxy) package, it offers 0.4W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The gull-wing termination and 1.27mm terminal pitch facilitate easy surface-mount assembly (SMD). Compliant with EU RoHS and classified under ECCN EAR99, it is ideal for industrial and instrumentation use.
