GS4B023570FBT

GS4B023570FBT Description

The GS4B023570FBT from TT Electronics/IRC is a high-precision 7-resistor thin-film network designed for surface-mount applications. Encased in a ceramic SOIC-8 package, it offers a 357Ω resistance per element with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this gull-wing-terminated array is ideal for space-constrained, high-reliability circuits. Its ceramic substrate enhances thermal performance, while the thin-film technology guarantees low noise and high accuracy.

GS4B023570FBT Features

• Precision Network: 7 resistors, each 357Ω ±1%, with ±50ppm/°C TCR for minimal drift.
• Robust Construction: Ceramic SOIC-8 case with rectangular profile (4.9mm x 5.99mm x 1.45mm ±0.1mm) and gull-wing leads for secure SMD mounting.
• High-Temperature Operation: Derated power up to 125°C, suitable for harsh environments.
• Low-Power Design: 0.05W/resistor (0.4W total) balances performance and energy efficiency.
• Automotive-Grade Alternatives: While not PPAP-certified, its ceramic core and thin-film tech make it a candidate for industrial/telecom applications.
• Non-RoHS Compliance: Note: Contains restricted materials; verify compatibility with environmental regulations.

GS4B023570FBT Applications

• Signal Conditioning: Precision voltage dividers in sensor interfaces or ADC/DAC circuits.
• Bus Termination: BUS-designated for impedance matching in high-speed digital systems (e.g., memory buses).
• Industrial Electronics: PLC modules, power supplies, and test equipment requiring stable resistance networks.
• Telecom Infrastructure: Line drivers, filter networks, and RF front-end circuits benefiting from low TCR.
• Aerospace & Defense: Avionics and military-grade hardware where ceramic durability is critical.

Conclusion of GS4B023570FBT

The GS4B023570FBT excels in precision analog and mixed-signal designs, combining thin-film accuracy, ceramic reliability, and compact SMD form factor. Its 1% tolerance and low TCR outperform carbon-based networks, while the SOIC-8 package ensures compatibility with automated assembly. Though not RoHS-compliant, it remains a robust choice for industrial, telecom, and high-temperature applications demanding long-term stability. Engineers should evaluate alternative RoHS-compliant models for eco-sensitive projects.
