GS4B011021CT

GS4B011021CT Description

The GS4B011021CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 7-resistor bussed network features a 1.02KΩ resistance value with an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. Encased in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount assembly. The thin-film technology and ceramic substrate provide superior stability, with a ±100ppm/°C temperature coefficient and operation up to 125°C. Rated for 100V maximum voltage and 0.4W total power dissipation, it combines robustness with precision.

GS4B011021CT Features

• High Precision: ±0.25% absolute tolerance for critical analog applications.
• Thermal Stability: ±100ppm/°C TCR ensures minimal drift across 70°C to 125°C.
• Compact & Durable: Ceramic case (SOIC) with 1.27mm terminal pitch for high-density PCB designs.
• Bussed Configuration: Simplifies circuit design by interconnecting resistors via a common node (BUS).
• Reliable Power Handling: 0.05W per resistor (0.4W total) at derated temperatures.
• Non-Automotive Grade: Suitable for industrial, telecom, and instrumentation use.

GS4B011021CT Applications

Ideal for:

• Precision voltage dividers in test/measurement equipment.
• Signal conditioning for ADCs/DACs in data acquisition systems.
• Impedance matching in RF and communication circuits.
• Feedback networks in op-amp configurations.
• Industrial control systems requiring stable, high-tolerance resistors.

Conclusion of GS4B011021CT

The GS4B011021CT excels in applications demanding tight tolerance, low TCR, and compact form factors. Its ceramic construction and thin-film technology offer long-term reliability, while the bussed design reduces component count in bus-oriented circuits. Though not PPAP or RoHS compliant, it remains a cost-effective solution for non-automotive precision electronics. Engineers will value its balance of performance, size, and thermal resilience in critical analog designs.
