GS7B022942DAT

GS7B022942DAT Description

The GS7B022942DAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying thermal conditions. Housed in a 14-pin narrow SOIC package, this bussed (BUS) network integrates 13 thin-film resistors with a 29.4KΩ resistance value and an exceptional ±0.5% absolute tolerance (±0.05% ratio tolerance). Its ±50ppm/°C temperature coefficient ensures minimal resistance drift across a wide operating range of -70°C to +125°C, making it suitable for precision analog and digital circuits. The SOIC-C series construction features a ceramic case style, providing superior thermal and mechanical stability compared to polymer-based alternatives. With a 0.7W total power rating (0.05W per resistor) and 100V maximum voltage rating, this component is engineered for reliability in compact, surface-mount designs.

GS7B022942DAT Features

• High Precision: Tight tolerances (±0.5%) and low TCR (±50ppm/°C) for stable performance.
• Robust Construction: Ceramic substrate enhances thermal dissipation and durability.
• Space-Efficient: 8.66mm × 5.99mm × 1.45mm SOIC package optimizes PCB real estate.
• Bussed Topology: Simplifies circuit design by interconnecting resistors via a common node.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power.
• Surface-Mount Ready: Gull-wing terminals with 1.27mm pitch for automated assembly.
• Non-Automotive: Ideal for industrial, medical, and instrumentation applications where PPAP compliance is not required.

GS7B022942DAT Applications

This resistor network excels in:

• Precision Voltage Dividers: Critical in ADC/DAC reference circuits due to low ratio tolerance.
