GQCA0188R7JGT Description

The GQCA0188R7JGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 24-pin QSOP package integrates 12 isolated resistors, each rated at 88.7Ω with a 5% tolerance and a ±100ppm/°C temperature coefficient. The ceramic case ensures excellent thermal stability, while the gull-wing termination facilitates secure surface-mount assembly. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments. Packaged in a tube, it meets industrial standards but is not PPAP or automotive-qualified.

GQCA0188R7JGT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive circuits.
• Isolated Resistor Design (ISOL): Each of the 12 resistors operates independently, reducing crosstalk.
• Robust Ceramic Package: Enhances thermal dissipation and mechanical durability.
• Compact QSOP Form Factor: 8.66mm x 6.02mm x 1.47mm dimensions with tight tolerances (±0.1mm length/height, ±0.2mm depth) save PCB space.
• Wide Operating Range: Functions reliably from -70°C to +125°C with derated power up to 125°C.
• High Voltage Tolerance: Supports up to 100V, ideal for industrial power systems.

GQCA0188R7JGT Applications

• Signal Conditioning: Isolated resistor networks are critical in ADC/DAC circuits and sensor interfaces.
• Medical Equipment: Stable performance suits patient monitoring systems and diagnostic tools.
• Industrial Control Systems: Withstands harsh environments in PLC modules and motor drives.
• Test & Measurement: Low TCR (±100ppm/°C) ensures accuracy in calibration instruments.
• Telecommunications: Used in filter networks and impedance matching for RF modules.

Conclusion of GQCA0188R7JGT

The GQCA0188R7JGT excels in applications demanding precision, isolation, and thermal resilience. Its thin-film technology, ceramic construction, and gull-wing termination provide superior performance over generic thick-film networks. While not RoHS-compliant or automotive-grade, it is a cost-effective solution for industrial, medical, and telecom systems requiring stable resistance values under varying conditions. Engineers will appreciate its compact design, high voltage capability, and reliability in critical circuits.
