GS7A036981GGT

GS7A036981GGT Description

The GS7A036981GGT from TT Electronics/IRC is a high-precision 7-resistor network designed for isolated circuit (ISOL) applications, housed in a 14-pin narrow SOIC ceramic package. This thin-film resistor network offers a 6.98KΩ resistance per element with a tight ±2% absolute tolerance and ±2% ratio tolerance, ensuring consistent performance in matched-resistance applications. The device operates across a wide temperature range (70°C to 125°C @ derated power) and maintains stability with a low ±25ppm/°C temperature coefficient (TCR). Its 0.1W power rating per resistor (0.7W total) and 100V maximum voltage rating make it suitable for precision analog and signal conditioning circuits.

GS7A036981GGT Features

• Ceramic SOIC Package: Robust rectangular ceramic case (8.66mm x 5.99mm x 1.45mm) with gull-wing leads for reliable surface-mount (SMD) assembly.
• High Stability: Thin-film technology ensures low noise, high accuracy, and long-term reliability.
• Isolated Resistors: 7 independent resistors (non-bussed) for flexible circuit design.
• Precision TCR: ±25ppm/°C ensures minimal resistance drift under thermal stress.
• Automotive & Industrial Compliance: While not PPAP or automotive-qualified, its wide operating range (-55°C to +125°C) suits harsh environments.
• Non-RoHS: May be preferred for legacy or high-reliability systems requiring leaded components.

GS7A036981GGT Applications

• Signal Conditioning: Ideal for amplifier gain networks, ADC/DAC reference dividers, and sensor calibration circuits.
• Medical & Test Equipment: Precision resistance matching for patient monitoring or lab instrumentation.
• Industrial Controls: Used in PLC analog I/O modules where isolation and stability are critical.
• Legacy Electronics: Suitable for military/aerospace systems requiring non-RoHS compliant parts.

Conclusion of GS7A036981GGT

The GS7A036981GGT excels in precision analog designs demanding low TCR, tight tolerance, and isolation. Its ceramic SOIC construction provides mechanical durability, while the thin-film resistors ensure repeatable performance. Though not RoHS-compliant, it remains a robust choice for high-reliability, industrial, and legacy applications where component longevity and accuracy are paramount. Engineers should evaluate its non-automotive status but can leverage its stable 6.98KΩ network for critical signal-path designs.
