GQCB0139R2FT

GQCB0139R2FT Description

The GQCB0139R2FT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It features 23 resistors in a 24-pin QSOP package with a 39.2Ω resistance value, 1% tolerance, and a ±100ppm/°C temperature coefficient. Encased in a ceramic substrate, this surface-mount (SMD) component offers excellent thermal stability and reliability, with a maximum operating temperature of 125°C and a derated power range of 70°C to 125°C. The gull-wing termination ensures secure PCB mounting, while the 0.05W (1/20) power rating per resistor and 1W total power rating make it suitable for compact, high-density designs.

GQCB0139R2FT Features

• Precision Thin Film Technology: Delivers stable performance with low noise and high accuracy (±1%).
• Robust Ceramic Case: Enhances thermal dissipation and mechanical durability.
• High Voltage Rating: Supports up to 100V, ideal for industrial and instrumentation applications.
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm height/length, ±0.2mm depth) for space-constrained layouts.
• BUS Circuit Designator: Optimized for bus line termination, voltage division, and pull-up/down circuits.
• Non-Automotive (PPAP No): Suitable for commercial and industrial use where PPAP compliance is not required.

GQCB0139R2FT Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage dividers in data acquisition systems.
• Termination Networks: For high-speed digital buses (e.g., DDR, PCIe) to reduce reflections.
• Embedded Systems: Pull-up/down resistors in microcontrollers and FPGAs.
• Test & Measurement Equipment: Stable reference circuits due to low TCR (±100ppm/°C).
• Medical Electronics: Reliable performance in diagnostic devices where consistency is critical.
