GS4A0238R3DCT

GS4A0238R3DCT Description

The GS4A0238R3DCT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding surface-mount applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 38.3Ω and an absolute tolerance of ±0.5%. The device operates over a wide temperature range (-55°C to +125°C) with a derated power range of 70°C to 125°C, ensuring stability in harsh environments. Its ±50ppm/°C temperature coefficient and 0.1W power rating per resistor (0.4W total) make it suitable for precision analog and digital circuits. The gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration.

GS4A0238R3DCT Features

• High Precision: ±0.5% absolute tolerance and ±0.25% ratio tolerance for matched resistance performance.
• Robust Construction: Ceramic case and thin-film technology ensure durability and long-term reliability.
• Isolated Design: Four independent resistors (ISOL circuit designator) minimize crosstalk in sensitive applications.
• Wide Voltage Range: Supports up to 100V maximum operating voltage.
• Compact Footprint: Measures 4.9mm (L) x 5.99mm (D) x 1.45mm (H) with tight tolerances (±0.1mm length/height, ±0.2mm depth).
• Surface-Mount Ready: SOIC package with gull-wing leads for automated assembly compatibility.

GS4A0238R3DCT Applications

• Precision Voltage Dividers: Ideal for ADC/DAC reference circuits due to low TCR and tight tolerance.
