GS4B034302JBT Description

The GS4B034302JBT from TT Electronics/IRC is a high-performance 7-resistor thin-film network designed for precision applications. Encased in a ceramic SOIC-8 package, it features a 43KΩ resistance per element with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this surface-mount (SMD) network is ideal for compact, high-reliability designs. Its gull-wing termination and 1.27mm pitch facilitate automated assembly, while the ceramic substrate enhances thermal stability and durability.

GS4B034302JBT Features

• Circuit Designator: BUS configuration for streamlined integration.
• Thin-Film Technology: Delivers superior accuracy (±5%) and low TCR (±25ppm/°C).
• Robust Construction: Ceramic case ensures high thermal conductivity and mechanical strength.
• Space-Efficient: Compact 4.9mm × 5.99mm × 1.45mm footprint (SOIC-8) suits dense PCB layouts.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, even at derated power.
• Automation-Friendly: Gull-wing leads and ±0.1mm dimensional tolerances ensure pick-and-place compatibility.
• Non-Automotive: Not PPAP-capable, but excels in industrial and telecom applications.
