GS4A0273R2CT

GS4A0273R2CT Description

The GS4A0273R2CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 73.2Ω resistance and an exceptional ±0.25% tolerance. The device operates over a wide temperature range of -70°C to +125°C, ensuring reliability in harsh environments. With a ±50ppm/°C temperature coefficient, it delivers stable performance under thermal stress. The SOIC-C series construction provides robust mechanical integrity, while the 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for precision circuits.

GS4A0273R2CT Features

• High Precision: ±0.25% absolute tolerance ensures accurate signal conditioning.
• Isolated Resistors: Four independent resistors (73.2Ω each) prevent crosstalk in sensitive circuits.
• Thermal Stability: ±50ppm/°C TCR minimizes resistance drift across temperature fluctuations.
• Robust Construction: Ceramic substrate and gull-wing termination enhance durability and solderability.
• Compact Footprint: Measures 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).
• Surface-Mount Design: SOIC package (1.27mm pitch) simplifies PCB integration in space-constrained designs.
