GS7B029102FT

GS7B029102FT Description

The GS7B029102FT from TT Electronics/IRC is a high-performance 13-resistor bussed network in a 14-pin narrow SOIC package. Designed for precision applications, it features a 91kΩ resistance value with a tight ±1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. The thin-film technology on a ceramic substrate delivers superior reliability and accuracy, while the gull-wing termination enables robust surface-mount (SMD) assembly. With a 0.7W total power rating (0.05W per resistor) and 100V maximum voltage rating, this network is engineered for demanding circuits requiring consistent signal integrity.

GS7B029102FT Features

• Bussed Architecture: Simplifies PCB layout by connecting multiple resistors to a common node (BUS).
• High Precision: ±1% absolute tolerance and ±50ppm/°C TCR for critical analog/digital systems.
• Robust Construction: Ceramic case (SOIC package) ensures thermal stability and mechanical durability.
• Space-Efficient: Compact 8.66mm × 5.99mm × 1.45mm dimensions with ±0.1mm length/height tolerances.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power at elevated temperatures.
• Industry-Standard Compliance: HTS 8533.21.00.20, ECCN EAR99, though non-RoHS (note for restricted applications).

GS7B029102FT Applications

Ideal for:

• Voltage Divider Networks: Precision attenuation in sensor interfaces or ADC circuits.
• Bus Termination: Impedance matching in high-speed digital systems (e.g., memory buses).
• Industrial Controls: Stable resistance in harsh environments (automation, power supplies).
• Test & Measurement Equipment: Calibration circuits demanding low drift over temperature.
• Aerospace & Defense: Non-RoHS compliance suits legacy systems with specific material requirements.
