GQCB011780GBT

GQCB011780GBT Description

The GQCB011780GBT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 24-pin QSOP package integrates 23 resistors with a 178Ω resistance value, offering a tight 2% tolerance and a low ±100ppm/°C temperature coefficient. Encased in a ceramic housing, it ensures superior thermal stability and durability. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in high-density PCB designs. Its gull-wing termination and surface-mount (SMD) configuration facilitate automated assembly, while the tube packaging protects components during handling and storage.

GQCB011780GBT Features

• Precision Thin Film Technology: Delivers stable performance with minimal drift over temperature fluctuations.
• High Power Handling: 1W total dissipation (1/20W per resistor) ensures robustness in power-sensitive applications.
• Wide Temperature Range: Operates from 70°C to 125°C, suitable for industrial and automotive environments (though not PPAP or Automotive qualified).
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances enable space-efficient designs.
• Low TCR: ±100ppm/°C ensures consistent resistance across thermal variations.
• Non-RoHS Compliant: Ideal for legacy systems or applications exempt from RoHS restrictions.
