GQCB0138R3JDT Description

The GQCB0138R3JDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 23-resistor array features a 38.3 Ohm resistance value with a 5% tolerance and a ±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 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for high-density PCB designs. The gull-wing termination and surface-mount (SMD) design facilitate easy assembly, while the rectangular ceramic case ensures durability and thermal stability.

GQCB0138R3JDT Features

• High-Density Integration: 23 resistors in a compact QSOP package (8.66mm x 6.02mm x 1.47mm) save board space.
• Precision Thin-Film Technology: Delivers low noise and high accuracy (±5% tolerance) for signal conditioning and voltage division.
• Robust Construction: Ceramic substrate enhances thermal performance and reliability in harsh environments.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power handling.
• Automated Assembly Friendly: Gull-wing leads and 0.64mm terminal pitch ensure compatibility with pick-and-place systems.
• Non-Automotive Grade: Ideal for industrial, telecom, and instrumentation applications where PPAP compliance is not required.
