GQ0A0363R4CCT

GQ0A0363R4CCT Description

The GQ0A0363R4CCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter-Small Outline Package) device features 10 isolated resistors, each with a 63.4 Ω resistance and an ultra-tight ±0.25% tolerance. The network operates over a wide temperature range of -70°C to +125°C, with a ±25ppm/°C temperature coefficient, ensuring stable performance in fluctuating thermal conditions. Encased in a ceramic package, it offers superior durability and thermal dissipation, making it ideal for high-reliability environments. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this component is engineered for precision analog and digital circuits.

GQ0A0363R4CCT Features

• High Precision: ±0.25% tolerance and ±25ppm/°C TCR for critical signal conditioning.
• Robust Construction: Ceramic case with gull-wing terminations for reliable surface-mount assembly.
• Isolated Resistors: 10 independent resistors (63.4 Ω each) in a QSOP-20 package, reducing crosstalk.
• Wide Operating Range: Stable performance from -70°C to +125°C, suitable for industrial and automotive-grade designs (though not PPAP-certified).
• Thin-Film Technology: Delivers low noise and high stability compared to thick-film alternatives.
• Compact Dimensions: 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length).

GQ0A0363R4CCT Applications

This resistor network excels in:

• Precision Voltage Dividers: Ideal for ADC/DAC reference circuits due to its low TCR and tight tolerance.
• Medical Equipment: High isolation and stability suit patient monitoring systems.
• Industrial Control Systems: Withstands harsh environments (e.g., PLCs, motor drives).
• Telecommunications: Low-noise signal processing in RF and baseband circuits.
• Test & Measurement: Calibration and sensor interfaces requiring minimal drift.

Conclusion of GQ0A0363R4CCT

The GQ0A0363R4CCT stands out for its precision, isolation, and rugged ceramic packaging, offering engineers a reliable solution for high-accuracy circuits. While not automotive-qualified, its wide temperature range and thin-film technology make it a top choice for industrial, medical, and telecom applications. Its QSOP-20 footprint balances space efficiency with performance, though designers should note its non-RoHS compliance. For systems demanding stable resistance under thermal stress, this network delivers exceptional value.
