GQ0A0130R9DDT Description

The GQ0A0130R9DDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP package integrates 10 isolated resistors, each with a 30.9Ω resistance value and a tight ±0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The device operates over a wide temperature range of 70°C to 125°C with a ±100ppm/°C temperature coefficient, maintaining stable performance under thermal stress. Its ceramic case and gull-wing termination provide robust mechanical and electrical reliability in surface-mount (SMD) applications, while the 100V maximum voltage rating and 1W total power dissipation (0.1W per resistor) make it suitable for moderate-power designs.

GQ0A0130R9DDT Features

• Precision Thin-Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• Isolated Resistor Network (ISOL): Each of the 10 resistors is electrically isolated, enabling flexible circuit design.
• High Power Density: 1W total power rating in a compact 8.66mm × 6.02mm × 1.47mm QSOP package.
• Wide Operating Range: Reliable performance from -55°C to +125°C (derated above 70°C).
• Strict Tolerance & TCR: ±0.5% resistance accuracy and ±100ppm/°C thermal drift ensure long-term consistency.
• Robust Construction: Ceramic substrate and gull-wing leads enhance durability in harsh environments.
