GS4A021873GFT

GS4A021873GFT Description

The GS4A021873GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 187KΩ resistance and a tight ±2% absolute tolerance (±1% ratio tolerance). Its SOIC package (4.9mm × 5.99mm × 1.45mm) ensures compact surface-mount integration, while the gull-wing termination facilitates reliable PCB connections. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -55°C to +125°C. The 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for demanding circuits.

GS4A021873GFT Features

• Isolated Resistors: Four independent 187KΩ elements with 2% tolerance for precise signal conditioning.
• Robust Construction: Ceramic substrate and thin-film technology ensure durability and low noise.
• Thermal Stability: ±50ppm/°C TCR minimizes resistance drift in varying environments.
• Compact & Reliable: SOIC-8 package (1.27mm pitch) optimizes board space; gull-wing leads enhance solderability.
• High Voltage Handling: Supports up to 100V, ideal for industrial and automotive-grade designs (though not PPAP/automotive-certified).
