GS4B034420JBT Description

The GS4B034420JBT from TT Electronics/IRC is a high-performance 7-resistor thin-film network in an 8-pin SOIC package, designed for precision applications. With a 442 Ω resistance per element (5% tolerance) and a ±25 ppm/°C temperature coefficient, it ensures stable performance across a 70°C to 125°C derated power range. The ceramic case and gull-wing termination provide robust mechanical and thermal stability, while the 0.4W total power rating (0.05W per resistor) makes it suitable for compact, power-sensitive designs. Its 100V maximum voltage rating and surface-mount (SMD) compatibility cater to modern PCB layouts.

GS4B034420JBT Features

• Thin-film technology: Delivers low noise and high precision (±25 ppm/°C TCR).
• Ceramic SOIC package: Enhances thermal dissipation and durability.
• BUS circuit design: Optimized for bus termination and signal conditioning.
• Tight tolerances: ±0.1mm height/length tolerances ensure consistent mounting.
• Wide temperature range: Operates reliably up to 125°C, ideal for industrial environments.
• Non-RoHS compliant: Suitable for legacy or specialized applications requiring alternative materials.

GS4B034420JBT Applications

This resistor network excels in:

• Bus termination for digital communication interfaces (e.g., CAN, SPI).
• Voltage division in sensor signal conditioning circuits.
• Impedance matching in high-frequency PCBs.
• Industrial control systems requiring stable performance under thermal stress.
• Automotive electronics (though not PPAP-certified, its rugged design suits non-safety-critical modules).
