GS4A027320JFT Description

The GS4A027320JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features thin-film technology, delivering a resistance value of 732Ω with an absolute tolerance of ±5% and a ratio tolerance of ±1%. Its ±50ppm/°C temperature coefficient ensures minimal resistance drift across the operating temperature range of 70°C to 125°C, making it suitable for demanding environments. The SOIC-C series construction offers 0.1W (1/10W) power rating per resistor (0.4W total), with a maximum voltage rating of 100V. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances durability and thermal performance.

GS4A027320JFT Features

• Isolated Circuit Design (ISOL): Ensures independent resistor performance, reducing crosstalk.
• High Stability: ±50ppm/°C TCR and 5% tolerance provide reliable performance in temperature-sensitive applications.
• Robust Construction: Ceramic case and SOIC package offer superior thermal and mechanical resilience.
• Precision Thin Film: Delivers consistent resistance values with low noise and high accuracy.
• Compact Footprint: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Wide Voltage Range: Supports up to 100V, ideal for industrial and automotive (non-AEC-Q200) applications.

GS4A027320JFT Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers and feedback networks in op-amp circuits.
• Industrial Control Systems: Isolated resistor arrays for PLCs and sensor interfaces.
• Test & Measurement Equipment: Stable reference resistors for calibration and instrumentation.
