GQCA0228R0JGT Description

The GQCA0228R0JGT 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 with a 28Ω resistance value and a 5% tolerance, ensuring consistent performance across demanding environments. The ceramic case style and gull-wing termination enable robust surface-mount (SMD) integration, while the ±50ppm/°C temperature coefficient guarantees minimal resistance drift over the -70°C to +125°C operating range. With a 100V maximum voltage rating and 0.1W power dissipation per resistor, this network is ideal for circuits requiring electrical isolation (ISOL) and compact form factors.

GQCA0228R0JGT Features

• Precision Thin Film Technology: Delivers stable resistance with low noise and high accuracy (±5%).
• Isolated Resistor Network: 12 independent resistors in a single QSOP package, reducing PCB footprint.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power.
• Robust Construction: Ceramic substrate enhances thermal stability and mechanical durability.
• High Voltage Tolerance: Supports up to 100V, suitable for industrial and automotive-grade designs (though not PPAP/automotive-certified).
• Surface-Mount Gull Wing Terminals: Ensures secure PCB attachment with a 0.64mm pitch for high-density layouts.
• Non-RoHS Compliant: May be preferred for legacy or specialized applications requiring specific material properties.
