GS4B021132CAT

GS4B021132CAT Description

The GS4B021132CAT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring a ceramic substrate and thin-film technology, it delivers exceptional stability with a ±50ppm/°C temperature coefficient and ±0.25% absolute tolerance. The network operates across a wide temperature range of 70°C to 125°C (derated) and offers a maximum voltage rating of 100V, making it suitable for precision analog and digital circuits. With a compact footprint (4.9mm x 5.99mm x 1.45mm) and gull-wing termination, it ensures reliable performance in space-constrained designs.

GS4B021132CAT Features

• High Precision: 0.25% tolerance and ±0.05% ratio tolerance for critical signal conditioning.
• Robust Construction: Ceramic case and thin-film resistors ensure low noise and long-term reliability.
• Thermal Performance: 0.4W total power rating (0.05W per resistor) with derating up to 125°C.
• Space-Efficient: SOIC package with 1.27mm terminal pitch for high-density PCB layouts.
• Automation-Friendly: Gull-wing leads enable smooth pick-and-place assembly.
• Non-Compliant with EU RoHS, which may be preferable for certain industrial or military applications requiring legacy materials.

GS4B021132CAT Applications

Ideal for:

• Voltage dividers and current sensing in precision instrumentation.
• Signal conditioning for ADCs/DACs in medical and test equipment.
• Impedance matching in RF and communication systems.
• Industrial control systems requiring stable resistance under thermal stress.
• Aerospace and defense applications where ceramic durability is critical.
