GS4A028061FAT Description

The GS4A028061FAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors with a resistance value of 8.06 kΩ and a tight ±1% absolute tolerance. The device operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient of ±50 ppm/°C, ensuring stable performance under thermal stress. Its SOIC-C series construction offers excellent power dissipation (0.1W per resistor, 0.4W total) and a maximum voltage rating of 100V, making it suitable for precision analog and digital circuits.

GS4A028061FAT Features

• Isolated Resistors: Four independent resistors with isolated elements, reducing crosstalk in sensitive circuits.
• High Precision: ±1% tolerance and ±0.05% ratio tolerance for critical signal conditioning.
• Robust Construction: Ceramic case and thin-film technology ensure durability and long-term reliability.
• Surface-Mount Design: Gull-wing termination and 1.27mm pitch for easy PCB integration.
• Thermal Stability: ±50 ppm/°C TCR minimizes resistance drift across operating temperatures.
• Compact Dimensions: 4.9mm (L) x 5.99mm (D) x 1.45mm (H) with tight tolerances for space-constrained designs.

GS4A028061FAT Applications

• Precision Voltage Dividers: Ideal for ADC/DAC reference circuits due to low ratio tolerance.
