GS4B034301JFT Description

The GS4B034301JFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. Encased in a ceramic substrate, it offers excellent thermal stability with a ±25ppm/°C temperature coefficient and a 4.3KΩ resistance value (±5% tolerance). Rated for 100V maximum voltage and 0.4W total power dissipation, it operates reliably across a -70°C to +125°C temperature range. The gull-wing termination and surface-mount design ensure compatibility with automated assembly processes, while its SOIC package (4.9mm x 5.99mm x 1.45mm) suits space-constrained PCBs.

GS4B034301JFT Features

• Bussed Network Topology: Simplifies circuit design by interconnecting resistors, reducing component count.
• Thin-Film Technology: Delivers superior accuracy (±5% absolute, ±1% ratio tolerance) and low noise.
• Wide Temperature Range: Stable performance from -70°C to +125°C, even at derated power (70°C–125°C).
• Robust Construction: Ceramic case ensures high thermal conductivity and mechanical durability.
• Automation-Friendly: Gull-wing leads and 1.27mm pitch enable seamless SMT integration.
• Non-Automotive/Non-PPAP: Ideal for industrial and commercial applications where PPAP compliance isn’t required.
