GS4A031212DAT

GS4A031212DAT Description

The GS4A031212DAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying thermal conditions. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features thin-film technology with a 12.1KΩ resistance value and an absolute tolerance of ±0.5%, ensuring exceptional accuracy. Its ±25ppm/°C temperature coefficient minimizes resistance drift, making it ideal for precision circuits. The SOIC-C series construction offers robust ceramic case durability, with a maximum operating temperature of 125°C and a derated power range of 70–125°C. Rated at 0.1W per resistor (0.4W total) and 100V maximum voltage, it suits space-constrained, high-reliability designs.

GS4A031212DAT Features

• Isolated Elements: Independent resistors (Circuit Designator: ISOL) for flexible circuit integration.
• High Precision: ±0.5% tolerance and ±0.05% ratio tolerance for critical analog/digital systems.
• Stable Performance: ±25ppm/°C TCR ensures minimal drift across -55°C to +125°C.
• Robust Construction: Ceramic case (SOIC package) with gull-wing termination for reliable surface mounting.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).
• Wide Voltage Range: Supports up to 100V, suitable for industrial and instrumentation use.

GS4A031212DAT Applications
