GS4B021872JT

GS4B021872JT Description

The GS4B021872JT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed for precision applications, it features a ceramic substrate with thin-film technology, ensuring stable performance across a wide temperature range (70°C to 125°C). With a resistance value of 18.7KΩ and a ±5% tolerance, this network offers reliable signal conditioning and voltage division in compact designs. Its ±50ppm/°C temperature coefficient minimizes resistance drift, while the 100V maximum voltage rating and 0.4W total power dissipation make it suitable for demanding environments. The gull-wing termination ensures secure surface-mount assembly, and the SOIC package (4.9mm x 5.99mm x 1.45mm) is optimized for space-constrained PCBs.

GS4B021872JT Features

• Bussed Network Design: Simplifies circuit layout with shared connections, reducing component count.
• Ceramic Case & Thin Film: Enhances thermal stability and precision compared to thick-film alternatives.
• High Power Handling: 0.05W per resistor (0.4W total) derated up to 125°C.
• Low TCR: ±50ppm/°C ensures minimal resistance variation under thermal stress.
• Robust Construction: SOIC package with ±0.1mm height/length tolerances for consistent mounting.
• Wide Voltage Range: Supports up to 100V, ideal for industrial and automotive (non-AECQ) applications.
• Non-RoHS Compliant: Suitable for legacy or specialized systems requiring leaded components.

GS4B021872JT Applications

This resistor network excels in:

• Analog Signal Processing: Voltage dividers, pull-up/pull-down networks in sensor interfaces.
• Industrial Controls: PLCs, motor drives, and power supplies requiring stable resistance under thermal cycling.
• Test & Measurement Equipment: Precision calibration circuits due to low TCR and tight tolerance.
• Legacy Electronics: Military/aerospace systems where RoHS compliance is not mandated.
• Space-Constrained PCBs: SOIC footprint saves space versus discrete resistors in high-density designs.
