GS7B031781CBT Description

The GS7B031781CBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in a 14-pin narrow SOIC package, it features 13 bussed (BUS) thin-film resistors with a 1.78KΩ resistance value and an exceptional ±0.25% absolute tolerance (±0.1% ratio tolerance). The device operates over a wide temperature range of -70°C to +125°C, with a ±25ppm/°C temperature coefficient, ensuring stability in harsh environments. Its 0.05W (1/20) power rating per resistor and 0.7W total power rating make it suitable for low-power, high-density circuits. The 100V maximum voltage rating and surface-mount gull-wing termination further enhance its reliability in compact designs.

GS7B031781CBT Features

• Precision Performance: ±0.25% tolerance and ±25ppm/°C TCR ensure minimal drift.
• Robust Construction: Ceramic case and thin-film technology provide durability and long-term stability.
• Space-Efficient: SOIC package (8.66mm x 5.99mm x 1.45mm) with 1.27mm terminal pitch optimizes PCB real estate.
• High Voltage Handling: Supports up to 100V, ideal for industrial and automotive (non-Automotive PPAP) applications.
• Thermal Resilience: Derated power up to 125°C ensures reliable operation under thermal stress.
• Non-RoHS Compliant: Suitable for legacy or specialized systems requiring non-compliant materials.

GS7B031781CBT Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces benefit from its tight tolerance.
• Industrial Controls: Stable performance in PLCs, motor drives, and power management systems.
• Test & Measurement Equipment: Low drift and high accuracy are critical for instrumentation.
• Aerospace & Defense: Ceramic construction and wide temperature range suit rugged environments.
• Legacy Electronics Repair: Non-RoHS compliance makes it a drop-in replacement for older designs.
