GS4B033921JT

GS4B033921JT Description

The GS4B033921JT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) package, designed for precision applications requiring stable thin-film resistance. With a 3.92KΩ resistance per element and a ±5% tolerance, this ceramic-based network ensures reliable performance in demanding environments. Its ±25ppm/°C temperature coefficient and 0.05W (1/20) power rating per resistor (0.4W total) make it suitable for circuits where thermal stability and power dissipation are critical. The 100V maximum voltage rating and 125°C maximum operating temperature further enhance its durability in industrial and automotive-adjacent systems (though it is not PPAP or Automotive qualified).

GS4B033921JT Features

• Ceramic substrate for superior thermal and mechanical stability.
• Thin-film technology ensures low noise and high precision (±5% tolerance).
• Bussed (BUS) circuit design simplifies PCB layout for common-node applications.
• Gull-wing termination and 1.27mm pitch for easy surface-mount assembly.
• Compact dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length).
• Wide temperature range: Derated operation from 70°C to 125°C.
• Non-RoHS compliant (note for restricted-material designs).

GS4B033921JT Applications

Ideal for:

• Voltage divider networks in precision analog circuits.
• Pull-up/pull-down resistor arrays in digital logic systems.
• Signal conditioning for sensors and instrumentation.
• Industrial control systems requiring robust, temperature-stable components.
• Power management circuits where bussed resistors reduce component count.

Conclusion of GS4B033921JT

The GS4B033921JT stands out for its ceramic construction, thin-film accuracy, and bussed topology, offering a balance of performance and space efficiency. While not suited for automotive-grade applications, its high-temperature resilience and low TCR make it a reliable choice for industrial, telecom, and consumer electronics.
