GS4B034120FDT

GS4B034120FDT Description

The GS4B034120FDT from TT Electronics/IRC is a high-precision 7-resistor thin-film network in an 8-pin SOIC package, designed for surface-mount applications. With a 412Ω resistance value and tight 1% tolerance, it delivers stable performance in demanding circuits. The ceramic-based construction ensures excellent thermal stability, operating across a -70°C to +125°C temperature range with a low ±25ppm/°C TCR. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, it suits precision analog and digital systems. The gull-wing termination facilitates reliable PCB mounting, while the compact 4.9mm × 5.99mm × 1.45mm footprint saves board space.

GS4B034120FDT Features

• Precision Thin Film: Low-noise, high-accuracy performance with ±25ppm/°C thermal drift.
• Robust Construction: Ceramic case ensures durability and heat dissipation.
• BUS Configuration: Ideal for bus termination, voltage division, and pull-up/down networks.
• Automotive-Grade Alternatives: While this model is not PPAP/Automotive certified, its 125°C max operating temp makes it suitable for industrial environments.
• Stable Power Handling: 0.4W total rating with derating up to 125°C.
• Strict Tolerances: ±0.1mm height/length and ±0.2mm depth tolerances ensure consistent placement.

GS4B034120FDT Applications

• Signal Conditioning: Precision dividers and filters in test/measurement equipment.
• Bus Termination: DDR memory, CAN, and I²C line termination.
• Industrial Controls: PLCs, sensor interfaces, and power management circuits.
• Medical Electronics: Low-drift networks for diagnostic devices.
• Telecom Infrastructure: Impedance matching in high-frequency PCBs.

Conclusion of GS4B034120FDT

The GS4B034120FDT excels in precision networks where stability, compactness, and low thermal drift are critical. Its ceramic SOIC package and thin-film technology offer superior performance over thick-film alternatives, though it lacks RoHS compliance. Engineers will value its repeatable accuracy in industrial, telecom, and instrumentation designs. For non-automotive applications requiring tight-tolerance resistor arrays, this model is a cost-effective solution.
