GS4B032940FDT Description

The GS4B032940FDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor array features a 294 Ohm resistance value per element with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a ceramic SOIC-8 package, it offers a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its compact dimensions (4.9mm x 5.99mm x 1.45mm) save board space.

GS4B032940FDT Features

• High Precision: 1% tolerance and ±25ppm/°C TCR for reliable signal conditioning.
• Robust Construction: Ceramic substrate enhances thermal stability and durability.
• Space-Efficient: SOIC-8 package with gull-wing leads optimizes PCB layout.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C.
• Low Power Dissipation: 0.05W per resistor minimizes heat buildup in dense designs.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, similar variants are available for harsh environments.

GS4B032940FDT Applications

Ideal for:

• Voltage Divider Networks: Precision attenuation in sensor interfaces.
• ADC/DAC Circuits: Stable reference resistors for data converters.
• Bus Termination: Matched impedance in high-speed digital systems (e.g., SPI, I²C).
• Medical Electronics: Low-drift performance for diagnostic equipment.
• Industrial Controls: Reliable operation in PLCs and motor drives.

Conclusion of GS4B032940FDT

The GS4B032940FDT excels in applications requiring tight tolerance, low thermal drift, and compact form factors. Its ceramic SOIC package and thin-film technology provide superior performance over carbon or thick-film alternatives, particularly in precision analog and high-frequency circuits. While not RoHS-compliant, it remains a cost-effective solution for prototyping and industrial use. Engineers should verify compatibility for automotive or high-reliability systems, as this model is unconfirmed for such applications.
