GS4A0142R2JDT Description

The GS4A0142R2JDT from TT Electronics/IRC is a high-reliability, ceramic-based resistor network designed for precision applications in demanding environments. This 4-resistor isolated network features a 42.2Ω resistance per element with a ±5% absolute tolerance and ±0.5% ratio tolerance, ensuring consistent performance in differential signal processing. Encased in an 8-pin narrow SOIC package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for robust surface-mount assembly. The thin-film technology delivers stable operation across a -70°C to +125°C temperature range, supported by a low ±100ppm/°C TCR. Rated for 100V maximum voltage and 0.1W per resistor (0.4W total), it combines durability with precision.
