GS4B024021FBT Description

The GS4B024021FBT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for precision applications, it features a 4.02KΩ resistance per element with a tight ±1% absolute tolerance and ±0.1% ratio tolerance, ensuring excellent matching characteristics. The thin-film technology delivers a low ±50ppm/°C temperature coefficient, enhancing stability across the -70°C to +125°C operating range. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, this network is engineered for reliability in demanding circuits.

GS4B024021FBT Features

• Ceramic SOIC Package: Robust construction with 4.9mm × 5.99mm × 1.45mm dimensions (±0.1mm tolerance) and gull-wing termination for secure surface mounting.
• Bussed Design: Simplifies PCB layout by connecting resistors in a common bus configuration (Circuit Designator: BUS).
• Precision Performance: Combines 1% tolerance with ±50ppm/°C TCR for minimal drift in temperature-sensitive applications.
• High Power Handling: 0.4W total dissipation (0.05W per resistor) at 125°C derated power, outperforming standard networks.
• Non-Automotive Grade: Suitable for industrial, telecom, and instrumentation use (PPAP: No, EU RoHS: Not Compliant).

GS4B024021FBT Applications

Ideal for voltage division, pull-up/pull-down networks, and impedance matching in:

• Precision analog circuits (e.g., sensor interfaces, ADCs/DACs).
• Communication systems requiring stable termination resistors.
• Power management modules where low TCR and tight tolerance are critical.
• Test/measurement equipment benefiting from matched resistor ratios.
