GS4A031543JBT Description

The GS4A031543JBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 154KΩ (±5% tolerance) and a low temperature coefficient of ±25ppm/°C. The device operates within a wide temperature range of 70°C to 125°C and delivers a power rating of 0.1W per resistor (0.4W total). Its SOIC-C series construction ensures robust performance in demanding environments, with a maximum voltage rating of 100V and gull-wing terminations for reliable surface-mount assembly.

GS4A031543JBT Features

• High Precision: ±5% absolute tolerance and ±0.1% ratio tolerance for matched resistance values.
• Stable Performance: Thin-film technology with a low ±25ppm/°C tempco ensures minimal drift.
• Durable Construction: Ceramic case and rectangular SOIC package (4.9mm x 5.99mm x 1.45mm) with tight tolerances (±0.1mm height, ±0.2mm depth).
• Isolated Design: Independent resistors reduce crosstalk, ideal for signal conditioning.
• Wide Operating Range: Supports -55°C to +125°C (derated above 70°C).
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its reliability suits industrial and telecom applications.
