GQCA021240DCT Description

The GQCA021240DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 124Ω resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case construction provides superior thermal stability, supporting operation across a wide temperature range of 70°C to 125°C with a ±50ppm/°C temperature coefficient. Rated for 100V maximum voltage and 0.1W power dissipation per resistor (1W total), this surface-mount network is ideal for space-constrained designs requiring reliable performance in harsh environments.

GQCA021240DCT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• Isolated Resistor Configuration (ISOL): Each of the 12 resistors operates independently, enhancing design flexibility.
• Robust Ceramic Package: Ensures mechanical durability and efficient heat dissipation.
• Gull Wing Termination: Facilitates reliable surface-mount assembly with a 0.64mm terminal pitch for high-density PCB layouts.
• Strict Tolerances: ±0.1mm length/height and ±0.2mm depth tolerances ensure consistent manufacturability.
• Non-Automotive, Non-PPAP: Suitable for industrial and commercial applications where PPAP compliance is not required.
