GS4B032801JCT Description

The GS4B032801JCT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 7-resistor array features a 2.8KΩ resistance value per resistor with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in an 8-pin SOIC package with gull-wing terminations, it offers excellent surface-mount compatibility and robust mechanical stability. The ceramic case style enhances thermal and electrical reliability, while the 0.4W total power rating (0.05W per resistor) makes it suitable for moderate-power circuits.

GS4B032801JCT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Compact & Robust Design: 4.9mm × 5.99mm × 1.45mm dimensions with tight tolerances (±0.1mm height/length, ±0.2mm depth) ensure consistent PCB integration.
• Wide Operating Range: Supports 100V maximum voltage and derated power up to 125°C, ideal for industrial environments.
• BUS Circuit Designator: Optimized for bus termination, voltage division, and pull-up/down applications.
• Non-Automotive (PPAP No): Best suited for industrial, telecom, and instrumentation systems where EU RoHS compliance is not mandatory.

GS4B032801JCT Applications
