GS4A012940BT Description

The GS4A012940BT by TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 294Ω resistance and an ultra-tight ±0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division. With a ±100ppm/°C temperature coefficient, it maintains stable performance across a wide operating range of -70°C to +125°C. The SOIC package (4.9mm x 5.99mm x 1.45mm) offers compact surface-mount compatibility, while the gull-wing termination ensures reliable solder joints. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it suits precision analog and digital circuits.
