GS4A022102DT

GS4A022102DT Description

The GS4A022102DT 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 21 kΩ resistance and an absolute tolerance of ±0.5%. Its ±50 ppm/°C temperature coefficient ensures stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The SOIC-C series construction provides robust ceramic encapsulation, enhancing durability and thermal dissipation. With a maximum voltage rating of 100V and a power rating of 0.4W (0.1W per resistor), this network balances precision and reliability in compact designs.

GS4A022102DT Features

• Isolated Elements: Four independent resistors for flexible circuit design.
• High Precision: ±0.5% tolerance and ±50 ppm/°C TCR for consistent performance.
• Robust Construction: Ceramic case with gull-wing terminations for mechanical and thermal resilience.
