GS4A021820DDT Description

The GS4A021820DDT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC (SOIC-C series) device features four isolated thin-film resistors, each with a resistance value of 182Ω and an absolute tolerance of ±0.5%. The network operates over a wide temperature range of 70°C to 125°C with a derated power rating, ensuring stable performance in thermally challenging environments. Its ±50ppm/°C temperature coefficient minimizes resistance drift, while the 0.1W (1/10) power rating per resistor (0.4W total) supports efficient power distribution. Encased in a rectangular ceramic package, it offers superior thermal stability and durability compared to polymer-based alternatives.

GS4A021820DDT Features

• Precision Performance: ±0.5% tolerance (absolute and ratio) ensures consistent signal integrity in critical circuits.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength.
• High Voltage Handling: 100V maximum rating suits industrial and automotive-grade applications.
• Stable TCR: ±50ppm/°C minimizes resistance variation across temperature fluctuations.
• Surface-Mount Design: Gull-wing termination (1.27mm pitch) facilitates automated PCB assembly.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length) for space-constrained layouts.

GS4A021820DDT Applications

This resistor network excels in:

• Isolation Circuits: Ideal for signal conditioning in medical devices or test equipment where galvanic isolation is critical.
• Industrial Controls: Reliable performance in PLC modules, motor drives, and power supplies due to high voltage tolerance.
• Precision Instrumentation: Used in ADC/DAC reference networks and feedback loops where low TCR and tight tolerance are paramount.
• Automotive Electronics: Suitable for sensor interfaces (non-automotive grade) requiring stable resistance under thermal stress.
