GQCA031870GFT

GQCA031870GFT Description

The GQCA031870GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. It features 12 isolated resistors, each with a 187Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. Encased in a ceramic QSOP package, this 24-pin SMD component offers excellent thermal stability with a ±25ppm/°C temperature coefficient and operates reliably across a wide temperature range of 70°C to 125°C. With a 0.1W power rating per resistor (1W total) and a 100V maximum voltage rating, it is engineered for durability in compact, high-density PCB layouts.

GQCA031870GFT Features

• Isolated Resistor Network: 12 resistors with independent isolation (ISOL), reducing crosstalk in sensitive analog/digital circuits.
• Precision Thin-Film Technology: Delivers low noise and high stability, ideal for signal conditioning and voltage division.
• Robust Ceramic QSOP Package: Provides superior thermal dissipation and mechanical strength compared to plastic alternatives.
• Gull Wing Termination: Ensures reliable surface-mount (SMD) soldering with a 0.64mm pitch for high-density designs.
• Extended Temperature Range: Operates at derated power up to 125°C, suitable for industrial and automotive-adjacent environments (though not PPAP/AEC-Q200 certified).
• Non-RoHS Compliant: May be preferred for legacy or specialized applications requiring leaded soldering processes.

GQCA031870GFT Applications

This resistor network excels in:

1. Analog Signal Processing: Precision dividers, feedback networks in op-amp circuits.
2. Industrial Controls: Isolated sensor interfaces, PLCs, and power management systems.
3. Test & Measurement Equipment: Calibration circuits, load banks, and instrumentation amplifiers.
4. Telecom Infrastructure: Line termination, impedance matching in high-frequency modules.
5. Legacy Military/Aerospace: Non-RoHS compliance aligns with certain MIL-SPEC requirements.
