GS4B021301BT

GS4B021301BT Description

The GS4B021301BT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Built with ceramic substrate and thin-film technology, it delivers exceptional stability with a ±50ppm/°C temperature coefficient and a ±0.1% absolute tolerance. The network features a 1.3KΩ resistance per element, rated for 0.05W (1/20) per resistor and 0.4W total power dissipation, operating reliably from 70°C to 125°C at derated power. Its 100V maximum voltage rating and gull-wing termination ensure robust performance in compact PCB layouts.

GS4B021301BT Features

• Precision & Stability: ±0.1% tolerance and ±50ppm/°C TCR for critical analog/digital circuits.
• Robust Construction: Ceramic case (SOIC-C series) enhances thermal and mechanical durability.
• Space-Efficient: Compact 4.9mm (L) × 5.99mm (D) × 1.45mm (H) dimensions with 1.27mm pitch.
• High Voltage Handling: Supports up to 100V, ideal for industrial and instrumentation use.
• Bussed Topology: Simplifies circuit design with shared common terminals (BUS configuration).
• Non-Automotive Grade: Suitable for commercial/industrial applications (PPAP: No, EU RoHS: Non-Compliant).

GS4B021301BT Applications

• Precision Voltage Dividers: In ADCs, DACs, and sensor interfaces requiring tight tolerance matching.
• Signal Conditioning: For op-amp feedback networks or gain-setting circuits in test equipment.
• Power Management: Current-limiting or biasing in power supplies (derated up to 125°C).
• Industrial PCBs: Where space constraints demand reliable, high-density resistor networks.

Conclusion of GS4B021301BT

The GS4B021301BT excels in precision applications with its thin-film ceramic construction, low TCR, and bussed design, offering superior performance over standard thick-film networks. While not RoHS-compliant, its high voltage tolerance and tight resistance matching make it ideal for industrial, medical, and instrumentation systems where accuracy and durability are paramount. Packaged in tubes for automated assembly, it balances cost-efficiency with technical rigor.
