GS4B021801CAT Description

The GS4B021801CAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 7-resistor bussed network is housed in an 8-pin narrow SOIC package, offering a compact footprint with 4.9mm (L) × 5.99mm (D) × 1.45mm (H) dimensions. Featuring thin-film technology, it delivers exceptional stability with a ±50ppm/°C temperature coefficient and ±0.25% absolute tolerance, ensuring reliable performance in precision circuits. The 1.8KΩ resistance value and 0.4W total power rating (0.05W per resistor) make it suitable for low-power, high-accuracy applications. Rated for 100V maximum voltage and 125°C operating temperature, it is engineered for durability in harsh environments.

GS4B021801CAT Features

• Ceramic SOIC-C Series: Robust construction with rectangular gull-wing termination for secure surface mounting.
• Bussed Network Design: Simplifies circuit layout with shared connections, reducing component count.
• High Precision: ±0.25% tolerance and ±0.05% ratio tolerance for critical analog/digital systems.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial/automotive (non-PPAP) use.
• Low TCR: ±50ppm/°C ensures minimal resistance drift.
• Non-RoHS Compliant: Suitable for legacy or specialized applications requiring non-compliant materials.
