GS4A022321GT

GS4A022321GT Description

The GS4A022321GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features 2.32KΩ resistance per element with a tight ±2% absolute tolerance and a low ±50ppm/°C temperature coefficient. Its thin-film technology ensures superior accuracy and reliability, while the ceramic case style enhances thermal dissipation and mechanical durability. Rated for 0.1W (1/10W) power dissipation per resistor (0.4W total) and 100V maximum voltage, it operates across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments.

GS4A022321GT Features

• Isolated Resistor Network: Four independent resistors in an SOIC-8 package, ideal for signal conditioning and voltage division.
• Precision Thin-Film Technology: Delivers ±2% tolerance and ±50ppm/°C TCR for stable performance under thermal stress.
• Robust Ceramic Construction: Enhances heat dissipation and mechanical strength compared to polymer-based networks.
• Surface-Mount Gull Wing Terminals: Ensures secure PCB mounting with a 1.27mm pitch for compact designs.
• Wide Operating Range: -70°C to +125°C with derated power up to 125°C, suitable for industrial and automotive-grade applications (though not PPAP/automotive-certified).
• Non-RoHS Compliant: May be preferred for legacy or high-reliability systems requiring leaded components.

GS4A022321GT Applications

• Analog Signal Processing: Precision voltage dividers, gain networks in op-amp circuits.
