GQ0A023900DAT Description

The GQ0A023900DAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 390 Ohm, 0.5% tolerance device features 10 isolated resistors in a 20-pin QSOP package with gull-wing surface-mount termination. Its ceramic case ensures durability, while the thin-film technology delivers exceptional stability (±50ppm/°C) and low noise. Rated for 1W total power (0.1W per resistor) and 100V maximum voltage, it operates reliably across a wide temperature range of -70°C to +125°C. The QSOP package (8.66mm x 6.02mm x 1.47mm) with ±0.1mm dimensional tolerances ensures consistent PCB compatibility.
