GS4A021243JGT

GS4A021243JGT Description

The GS4A021243JGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a resistance value of 124KΩ and a ±5% absolute tolerance. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The SOIC-C series construction offers robust ceramic substrate reliability, while the gull-wing termination facilitates easy surface-mount assembly. With a maximum voltage rating of 100V and a power rating of 0.4W (0.1W per resistor), this network balances compactness with durability.

GS4A021243JGT Features

• Isolated Resistors: Four independent resistors (124KΩ each) prevent crosstalk, ideal for signal isolation.
• High Stability: ±50ppm/°C TCR and ±2% ratio tolerance ensure precision in voltage division and feedback circuits.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength.
• Surface-Mount Ready: Gull-wing leads (1.27mm pitch) and SOIC package (4.9mm x 5.99mm x 1.45mm) comply with automated PCB assembly.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, suited for industrial and automotive (non-PPAP) applications.
• High Voltage Tolerance: 100V maximum rating supports power supply and measurement circuits.

GS4A021243JGT Applications

• Precision Analog Circuits: Voltage dividers, gain networks, and feedback loops in instrumentation.
• Signal Conditioning: Isolation and impedance matching in sensor interfaces (e.g., thermocouples, strain gauges).
• Power Management: Current limiting and bias networks in DC/DC converters.
• Industrial Electronics: Control systems, PLCs, and motor drives requiring stable resistance under thermal stress.
• Test & Measurement Equipment: Calibration and reference circuits demanding low TCR and tight tolerance.

Conclusion of GS4A021243JGT

The GS4A021243JGT excels in applications requiring high precision, thermal stability, and compact form factor. Its ceramic substrate, isolated thin-film resistors, and wide operating range make it a superior choice over polymer-based networks in harsh environments. While not PPAP-certified for automotive use, it is ideal for industrial, medical, and test equipment where reliability and accuracy are critical. Engineers will appreciate its balance of performance, durability, and ease of integration into surface-mount designs.
