GS7B021271CBT Description

The GS7B021271CBT from TT Electronics/IRC is a high-precision ceramic thin-film resistor network designed for demanding applications requiring tight tolerance and stable performance. Housed in a 14-pin narrow SOIC package, this bussed (BUS) network integrates 13 resistors, each with a 1.27KΩ resistance and an absolute tolerance of ±0.25%, ensuring exceptional accuracy. The device operates over a wide temperature range of -70°C to +125°C with a low temperature coefficient of ±50ppm/°C, making it ideal for environments with thermal fluctuations. Its 0.05W (1/20) power rating per resistor and 100V maximum voltage rating provide reliable performance in compact, space-constrained designs.

GS7B021271CBT Features

• Precision Performance: ±0.25% absolute tolerance and ±0.1% ratio tolerance for critical analog/digital circuits.
• Robust Construction: Ceramic thin-film technology ensures long-term stability and low noise.
• Space-Efficient: SOIC package (8.66mm x 5.99mm x 1.45mm) with gull-wing terminations for easy surface mounting.
• Thermal Resilience: Operates up to 125°C with derated power handling at elevated temperatures.
• Bussed Configuration: Simplifies PCB layout by reducing discrete component count.
• Non-Automotive Grade: Suitable for industrial, medical, and instrumentation applications where PPAP compliance is not required.
