GS4A012210BT

GS4A012210BT Description

The GS4A012210BT from 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 221Ω resistance and an ultra-tight ±0.1% tolerance. Encased in a robust rectangular ceramic SOIC package, it offers excellent thermal stability with a ±100ppm/°C temperature coefficient and operates reliably across a wide temperature range of -70°C to +125°C. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, this network is engineered for precision signal conditioning, voltage division, and impedance matching in space-constrained designs.

GS4A012210BT Features

• High Precision: ±0.1% absolute tolerance ensures minimal deviation in critical circuits.
• Isolated Elements: Four independent resistors (221Ω each) eliminate crosstalk for clean signal integrity.
• Robust Construction: Ceramic SOIC case provides superior thermal dissipation and mechanical durability.
