GQ0A034300DT Description

The GQ0A034300DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding circuit isolation and signal conditioning applications. This 10-resistor array features a 430Ω resistance value with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 20-pin QSOP package with gull-wing terminations, it offers a compact 8.66mm × 6.02mm × 1.47mm (L×D×H) footprint, making it ideal for space-constrained surface-mount (SMD) designs. The ceramic case provides robust thermal and mechanical stability, while the 100V maximum voltage rating and 1W total power dissipation (0.1W per resistor) suit medium-power applications.

GQ0A034300DT Features

• Precision Performance: Thin-film technology delivers ±0.5% tolerance and ±25ppm/°C TCR for minimal drift in critical circuits.
• Robust Construction: Ceramic substrate enhances thermal conductivity and durability under thermal stress.
• High-Density Integration: 10 isolated resistors in a QSOP-20 package optimize PCB space.
• Reliable Termination: Gull-wing leads ensure secure soldering and mechanical stability.
• Wide Operating Range: Rated for 125°C max temperature and 100V isolation, suitable for industrial environments.
• Non-Automotive: Compliant with EAR99 (ECCN) but not PPAP-certified, ideal for non-automotive precision electronics.

GQ0A034300DT Applications
