GS7B031872JBT Description

The GS7B031872JBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in a 14-pin narrow SOIC package, it features 13 bussed (BUS) thin-film resistors with a 18.7KΩ resistance value and a ±5% absolute tolerance. The device operates within a wide temperature range of 70°C to 125°C and offers a low temperature coefficient of ±25ppm/°C, ensuring stable performance under thermal stress. With a power rating of 0.7W (0.05W per resistor) and a maximum voltage rating of 100V, this network is engineered for reliability in demanding circuits. Its gull-wing termination and surface-mount design facilitate easy integration into compact PCB layouts.

GS7B031872JBT Features

• Ceramic SOIC-C Series: Robust construction with rectangular package (8.66mm × 5.99mm × 1.45mm) and tight tolerances (±0.1mm height, ±0.2mm depth).
• Thin-Film Technology: Delivers high precision (±0.1% ratio tolerance) and low noise, ideal for signal conditioning.
• Bussed Configuration: Simplifies circuit design by connecting multiple resistors to a common node, reducing component count.
• Wide Operating Range: Supports -55°C to 125°C with derated power up to 125°C, suited for industrial environments.
