GS7B022942CT

GS7B022942CT Description

The GS7B022942CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in a 14-pin narrow SOIC package, this bussed (BUS) configuration integrates 13 thin-film resistors, each with a 29.4 kΩ resistance and an exceptional ±0.25% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a ±50 ppm/°C temperature coefficient, ensuring stability in harsh environments. Its 0.05W (1/20) power rating per resistor and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The SOIC-C series construction features gull-wing termination for reliable surface-mount (SMD) assembly, with tight dimensional tolerances (±0.1mm height/length, ±0.2mm depth).

GS7B022942CT Features

• High Precision: ±0.25% tolerance and ±50 ppm/°C TCR for critical signal conditioning.
• Robust Construction: Ceramic substrate and thin-film technology ensure long-term reliability.
• Space-Efficient: Compact 8.66mm × 5.99mm × 1.45mm footprint (SOIC-14) saves PCB real estate.
• Bussed Design: Simplified routing for common bus applications (e.g., pull-up/pull-down networks).
• Wide Operating Range: Derated power up to 125°C, ideal for industrial/automotive-adjacent systems (non-Automotive PPAP).
• Low Power Dissipation: 0.7W total power rating (0.05W per resistor) balances performance and thermal management.

GS7B022942CT Applications

• Precision Voltage Dividers: Used in sensor interfaces and ADC/DAC reference circuits.
• Bus Termination Networks: Ideal for SPI, I²C, or CAN bus line termination.
• Medical/Test Equipment: Stable performance in calibration modules or instrumentation amplifiers.
• Industrial Controls: PLCs, motor drives, and power supplies requiring tight-tolerance resistors.
• Aerospace & Defense: Non-RoHS compliant version suits legacy or specialized systems.
