GQ8A012740BT

GQ8A012740BT Description

The GQ8A012740BT from TT Electronics/IRC is a high-precision, thin-film resistor network designed for demanding isolation circuit applications. This 8-resistor array features a 274Ω resistance per element with an ultra-tight 0.1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. Housed in a ceramic QSOP-16 package with gull-wing terminations, it offers 0.75W (3/4W) total power dissipation (0.1W per resistor) and a 100V maximum voltage rating. Its isolated (ISOL) circuit design and surface-mount (SMD) compatibility make it ideal for compact, high-reliability designs.

GQ8A012740BT Features

• Precision Performance: 0.1% tolerance and ±100ppm/°C TCR for stable operation in temperature-sensitive environments.
• Robust Construction: Ceramic case ensures durability and thermal stability, with a 1.47mm low profile for space-constrained PCBs.
• High Power Handling: 0.75W total power rating (0.1W per resistor) derated up to 125°C.
• Isolated Design: Independent resistors (ISOL configuration) prevent crosstalk in critical signal paths.
• Surface-Mount Ready: QSOP-16 package with 0.64mm pitch gull-wing leads for automated assembly.
• Non-Automotive: Suitable for industrial, medical, and telecom applications requiring precision without PPAP compliance.

GQ8A012740BT Applications

• Isolation Circuits: Ideal for signal conditioning in ADC/DAC interfaces, sensor bridges, and medical instrumentation.
