GS4A022002CT

GS4A022002CT Description

The GS4A022002CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a 20KΩ resistance and an exceptional ±0.25% tolerance. Its ±50ppm/°C temperature coefficient ensures stability across a wide operating range of -70°C to +125°C, making it suitable for environments with fluctuating thermal conditions. The SOIC-C series construction provides robust mechanical integrity, while the gull-wing termination facilitates reliable surface-mount assembly. With a maximum voltage rating of 100V and a power rating of 0.4W (0.1W per resistor), this network balances precision with durability.

GS4A022002CT Features

• High Precision: ±0.25% absolute tolerance ensures accurate signal conditioning.
• Stable Performance: ±50ppm/°C TCR minimizes resistance drift under thermal stress.
• Isolated Design: Four independent resistors eliminate crosstalk in critical circuits.
• Robust Construction: Ceramic substrate and SOIC package enhance reliability in harsh conditions.
• Surface-Mount Ready: Gull-wing terminals and 1.27mm pitch simplify PCB integration.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C.
• Low Power Dissipation: 0.1W per resistor (0.4W total) optimizes energy efficiency.
