GS4A035762FT

GS4A035762FT Description

The GS4A035762FT 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 57.6 kΩ resistance and a tight ±1% tolerance. The network operates over a wide temperature range of 70°C to 125°C with a derated power capability, ensuring stability in demanding environments. Its ±25 ppm/°C temperature coefficient minimizes resistance drift, making it ideal for circuits requiring long-term accuracy. The SOIC package with gull-wing termination facilitates easy surface-mount assembly, while the ceramic case enhances thermal and mechanical durability.

GS4A035762FT Features

• Isolated Circuit Design: Four independent resistors (ISOL configuration) prevent crosstalk, suitable for multi-channel isolation.
• Precision Performance: 1% tolerance and ±25 ppm/°C TCR ensure consistent operation in precision analog/digital systems.
• Robust Construction: Ceramic substrate offers superior thermal conductivity and mechanical strength vs. polymer-based networks.
• High Voltage Handling: Supports up to 100V, making it viable for industrial and instrumentation applications.
• Compact & Reliable: 4.9mm × 5.99mm footprint with 1.45mm height saves PCB space; 0.1W/resistor (0.4W total) power rating balances performance and size.
• Stable Derating: Maintains functionality up to 125°C, outperforming standard networks with limited high-temperature operability.

GS4A035762FT Applications

• Signal Conditioning: Isolated resistor networks in ADC/DAC reference circuits, ensuring minimal interference.
