GS4B018872CAT

GS4B018872CAT Description

The GS4B018872CAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features 7 bussed (BUS) thin-film resistors with a 88.7 kΩ resistance value and an exceptional ±0.25% absolute tolerance (±0.05% ratio tolerance). Encased in a rectangular ceramic SOIC package, it offers superior thermal stability with a ±100 ppm/°C temperature coefficient and operates reliably across a -70°C to +125°C temperature range. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, this network is engineered for precision and durability in surface-mount (SMD) configurations.

GS4B018872CAT Features

• High Precision: Tight tolerance (±0.25%) and low TCR (±100 ppm/°C) ensure stable performance in varying environments.
• Robust Construction: Ceramic case and gull-wing termination enhance mechanical and thermal resilience.
• Space-Efficient: Compact 4.9mm × 5.99mm × 1.45mm footprint (SOIC package) suits high-density PCB designs.
• Bussed Topology: Simplifies circuit design by interconnecting resistors, reducing external wiring.
• Wide Operating Range: Derated power up to 125°C makes it suitable for industrial and automotive (non-PPAP) applications.
• Non-RoHS Compliant: Ideal for legacy or specialized systems requiring non-compliant materials.

GS4B018872CAT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, sensor interfaces, and feedback networks where ratio tolerance is critical.
• Industrial Controls: PLCs, motor drives, and power supplies requiring stable resistance under thermal stress.
• Test & Measurement Equipment: Calibration tools and signal conditioning modules demanding low drift.
• Aerospace & Defense: Non-RoHS compliance suits legacy systems in harsh environments.
