GS4A021151DBT Description

The GS4A021151DBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying conditions. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a resistance value of 1.15 kΩ and an absolute tolerance of ±0.5%, ensuring exceptional accuracy. The network operates over a wide temperature range of -55°C to +125°C, with a derated power range of 70°C to 125°C, making it suitable for environments with thermal fluctuations. Its ±50 ppm/°C temperature coefficient guarantees minimal resistance drift, while the 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) ensure reliable operation in low-power circuits.

GS4A021151DBT Features

• Precision Performance: Tight tolerance (±0.5%) and low TCR (±50 ppm/°C) for stable operation.
• Robust Construction: Ceramic substrate and gull-wing termination enhance durability and solderability.
• Isolated Design: Four independent resistors in an SOIC package, ideal for space-constrained layouts.
• High-Temperature Suitability: Operates up to 125°C, with derating up to 125°C.
• Surface-Mount Compatibility: SOIC-8 package (4.9mm x 5.99mm x 1.45mm) with 1.27mm terminal pitch for easy PCB integration.
• Non-Automotive/Non-PPAP: Suitable for industrial and commercial applications where PPAP compliance is not required.

GS4A021151DBT Applications

This resistor network excels in precision analog and digital circuits, including:

• Signal conditioning in sensor interfaces and data acquisition systems.
• Voltage division and impedance matching in communication equipment.
• Feedback networks for op-amps and ADCs/DACs.
• Medical instrumentation requiring stable, low-drift resistance.
• Industrial control systems where temperature resilience is critical.

Conclusion of GS4A021151DBT

The GS4A021151DBT combines high precision, thermal stability, and compact design, making it a superior choice for engineers needing reliable resistor networks in harsh environments. Its isolated thin-film resistors, ceramic construction, and tight tolerances set it apart from generic arrays, particularly in applications demanding long-term accuracy. While not automotive-grade, its performance suits industrial, medical, and telecom systems where consistency under thermal stress is paramount.
