GS4A011181JBT Description

The GS4A011181JBT 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 1.18KΩ resistance per element with an absolute tolerance of ±5% and an exceptional ratio tolerance of ±0.1%. Its thin-film technology ensures low noise and high reliability, while the ceramic case style enhances thermal dissipation and mechanical durability. Rated for 0.1W per resistor (0.4W total), it operates across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments.

GS4A011181JBT Features

• Isolated Circuit Design: Each of the 4 resistors is electrically isolated, enabling flexible circuit configurations.
• High Precision: ±100ppm/°C temperature coefficient ensures minimal drift under thermal stress.
• Robust Construction: Ceramic substrate and gull-wing termination provide superior thermal and mechanical stability.
• Surface-Mount Compatibility: SOIC package (4.9mm x 5.99mm x 1.45mm) with 1.27mm terminal pitch facilitates easy PCB integration.
• Wide Voltage Range: Supports up to 100V maximum voltage, ideal for industrial and automotive applications (though not PPAP/automotive-certified).
• Non-RoHS Compliant: Suitable for legacy or specialized systems where RoHS exemptions apply.
