GS4A035492JBT Description

The GS4A035492JBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 54.9 kΩ and a tight ±5% absolute tolerance. The network operates over a wide temperature range of -70°C to +125°C, ensuring stability in harsh environments. Its ±25 ppm/°C temperature coefficient minimizes resistance drift, while the 0.1W (1/10) power rating per resistor (0.4W total) supports reliable performance in compact circuits. Encased in a rectangular ceramic SOIC package, it offers superior thermal and mechanical durability compared to polymer-based alternatives.

GS4A035492JBT Features

• Isolated Circuit Design: Four independent resistors (ISOL configuration) prevent crosstalk, ideal for precision signal conditioning.
• High Stability: Thin-film technology and ±25 ppm/°C TCR ensure minimal drift under thermal stress.
• Robust Construction: Ceramic case enhances heat dissipation and withstands mechanical stress.
• Space-Efficient: Compact 4.9mm × 5.99mm × 1.45mm footprint with 1.27mm gull-wing pitch for high-density PCB layouts.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and automotive (non-AECQ) applications.
• Strict Tolerances: ±5% absolute and ±0.1% ratio tolerance for matched resistor pairs.

GS4A035492JBT Applications

Conclusion of GS4A035492JBT

The GS4A035492JBT excels in applications demanding high precision, thermal stability, and isolation. Its ceramic SOIC package and thin-film resistors provide superior performance over epoxy-based networks, particularly in extreme temperatures. While not automotive-grade (PPAP/Non-AECQ), it is a cost-effective solution for industrial and medical designs where low drift and tight tolerances are paramount. Engineers should verify RoHS compliance for regulated markets.
