GQCB012491FBT Description

The GQCB012491FBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It features 23 resistors arranged in a BUS circuit design, each with a 2.49KΩ resistance, 1% tolerance, and a ±100ppm/°C temperature coefficient. Encased in a ceramic QSOP package, this 24-pin device offers 1W total power dissipation (0.05W per resistor) and operates within a wide temperature range of 70°C to 125°C. Its gull-wing termination and surface-mount design ensure reliable PCB integration, while the 100V maximum voltage rating enhances durability in high-voltage circuits.

GQCB012491FBT Features

• Precision & Stability: Thin-film technology ensures low noise and high accuracy (±1% tolerance, ±100ppm/°C).
• Robust Construction: Ceramic case and gull-wing leads provide mechanical strength and thermal resilience.
• Compact & Dense: 8.66mm × 6.02mm × 1.47mm footprint with 0.64mm pitch saves board space.
• High Power Handling: 1W total power (distributed across 23 resistors) suits power-sensitive designs.
• Automated Assembly Friendly: QSOP package and tube packaging streamline high-volume production.

GQCB012491FBT Applications

Ideal for precision analog and digital circuits, the GQCB012491FBT excels in:

• Signal Conditioning: Voltage dividers, DAC/ADC interfaces.
• Industrial Controls: PLCs, sensor arrays, and feedback networks.
• Telecom & Networking: Line termination, impedance matching.
• Test & Measurement Equipment: Calibration circuits, reference networks.
  Its non-automotive (PPAP No) and non-RoHS status may limit use in regulated sectors but makes it suitable for legacy or specialized industrial systems.
