GS4A031800DDT

GS4A031800DDT Description

The GS4A031800DDT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network offers a 180Ω resistance value with an absolute tolerance of ±0.5% and a ratio tolerance of ±0.5%. Its thin-film technology ensures excellent stability, while the ±25ppm/°C temperature coefficient guarantees reliable performance across a wide temperature range (70°C to 125°C). The device features a 0.1W (1/10W) power rating per resistor (0.4W total), a 100V maximum voltage rating, and gull-wing terminations for secure surface mounting. With EU RoHS non-compliance, it is ideal for non-regulated industrial environments.

GS4A031800DDT Features

• Precision Performance: Ultra-tight tolerances (±0.5%) and low TCR (±25ppm/°C) ensure accuracy in critical circuits.
• Robust Construction: Ceramic case and SOIC package provide durability and thermal stability.
• Isolated Design: Independent resistors minimize crosstalk, ideal for signal isolation applications.
• Space-Efficient: Compact 4.9mm × 5.99mm footprint with a 1.45mm profile suits high-density PCB layouts.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated above 70°C).
• Automotive-Grade Alternatives: While not PPAP/automotive-certified, similar models are available for automotive use.
