GQCB018251BT Description

The GQCB018251BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 23-resistor array features an 8.25KΩ resistance value per element with an ultra-tight 0.1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 24-pin QSOP ceramic package, it offers a compact 8.66mm × 6.02mm × 1.47mm footprint with gull-wing SMD termination for reliable surface-mount assembly. Rated for 1W total power dissipation (0.05W per resistor) and 100V maximum voltage, this network is ideal for precision analog and digital circuits requiring matched resistance values.

GQCB018251BT Features

• High Precision: 0.1% tolerance and ±100ppm/°C TCR for critical signal conditioning.
• Robust Construction: Ceramic case ensures durability and thermal stability.
• Space-Efficient: QSOP package (8.66mm × 6.02mm) with 0.64mm pitch for high-density PCB layouts.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Low-Power Design: 1/20W per resistor (1W total) minimizes heat buildup.
