GS4A021780CCT

GS4A021780CCT Description

The GS4A021780CCT 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 resistance value of 178Ω and an absolute tolerance of ±0.25%. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating range of 70°C to 125°C. The network is rated for 0.1W per resistor (0.4W total) and supports a maximum voltage of 100V, making it suitable for precision analog and digital circuits.

GS4A021780CCT Features

• High Precision: Tight tolerance (±0.25%) and low TCR (±50ppm/°C) for accurate signal conditioning.
• Robust Construction: Ceramic substrate and gull-wing termination enhance durability and solderability.
• Isolated Design: Independent resistors reduce crosstalk, ideal for multi-channel systems.
• Compact Footprint: Measures 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with a 1.27mm terminal pitch, saving PCB space.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Surface-Mount Compatibility: SOIC package facilitates automated assembly processes.
