GQCA021820CCT

GQCA021820CCT Description

The GQCA021820CCT 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 182Ω resistance value and an exceptional ±0.25% tolerance. Encased in a ceramic package, it offers superior thermal stability and reliability, with a ±50ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the 0.1W (1/10W) power rating per resistor and 1W total power rating make it suitable for precision circuits requiring consistent performance under load.

GQCA021820CCT Features

• High Precision: ±0.25% tolerance and ±50ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical durability.
• Isolated Resistors: 12 independent resistors (ISOL circuit designator) prevent crosstalk in multi-channel systems.
• Compact & Reliable: QSOP package (8.66mm × 6.02mm × 1.47mm) with ±0.1mm dimensional tolerances for high-density PCB layouts.
• Wide Voltage Range: Supports up to 100V maximum voltage, ideal for industrial and instrumentation use.
• Stable Performance: Thin-film technology delivers low noise and long-term stability compared to thick-film alternatives.
