GS8A022212CT Description

The GS8A022212CT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for isolation (ISOL) applications. Encased in a ceramic SOIC-16 package, it offers a 22.1KΩ resistance per resistor with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The device delivers 0.1W power dissipation per resistor (0.8W total) and supports 100V maximum voltage, making it suitable for demanding analog and digital circuits. Its gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic substrate enhances thermal performance and durability.

GS8A022212CT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±0.25%) for critical signal conditioning.
• Isolated Resistor Network: Each of the 8 resistors is electrically isolated, ideal for differential signaling or redundancy.
• Wide Temperature Range: Stable performance from -70°C to +125°C with derated power at elevated temperatures.
• Robust Construction: Ceramic case ensures superior heat dissipation and mechanical strength vs. plastic alternatives.
• Compact & Reliable: 9.91mm x 5.99mm footprint with ±0.1mm length/height tolerances for consistent PCB integration.
• Automation-Friendly: Gull-wing leads (1.27mm pitch) and tube packaging streamline high-volume SMT processes.
