GQCA021001DBT

GQCA021001DBT Description

The GQCA021001DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP package features 12 isolated 1KΩ resistors with a tight tolerance of ±0.5% and a low temperature coefficient of ±50ppm/°C, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) assembly, while the 0.1W (1/10W) power rating per resistor (1W total) and 100V maximum voltage rating make it suitable for precision analog and digital circuits. Packaged in a tube, this non-automotive, non-PPAP-compliant component is ideal for prototyping and low-to-medium volume production.

GQCA021001DBT Features

• High Precision: ±0.5% tolerance and ±50ppm/°C TCR ensure minimal drift.
• Robust Construction: Ceramic substrate enhances thermal stability and durability.
• Compact Design: 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances.
• Isolated Resistors: 12 independent 1KΩ resistors (ISOL circuit designator) for flexible circuit design.
• Surface-Mount Ready: Gull-wing terminals with 0.64mm pitch for easy PCB integration.
• Wide Operating Range: Derated power up to 125°C, suitable for industrial environments.
• Non-RoHS: May be preferred for legacy or specialized applications requiring non-compliant materials.

GQCA021001DBT Applications

• Precision Voltage Dividers: Ideal for ADC/DAC reference circuits due to low TCR and tight tolerance.
• Signal Conditioning: Used in sensor interfaces and instrumentation amplifiers.
• Industrial Controls: Reliable performance in PLCs, motor drives, and power management systems.
• Medical Electronics: Stable resistance in diagnostic equipment where accuracy is critical.
• Telecom Infrastructure: Suitable for RF matching networks and filter circuits.
