GQ0A0156R2DT

GQ0A0156R2DT Description

The GQ0A0156R2DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 10 isolated resistors, each with a 56.2 Ω resistance, a tight 0.5% tolerance, and a low ±100ppm/°C temperature coefficient. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. Its gull-wing termination ensures secure surface-mount (SMD) assembly, while the 0.64mm terminal pitch accommodates high-density PCB layouts.

GQ0A0156R2DT Features

• Precision Performance: Thin-film technology delivers 0.5% tolerance and ±100ppm/°C TCR for stable operation across 70°C to 125°C.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength, ideal for harsh environments.
• High Power Handling: 1W total dissipation (0.1W per resistor) supports power-sensitive designs.
• Isolated Design: 10 independent resistors (ISOL circuit designator) prevent crosstalk in multi-channel systems.
• Compact & Dense: 8.66mm length, 6.02mm depth, and 1.47mm height enable space-efficient layouts in QSOP packages.
• Industry-Standard Compliance: EAR99 ECCN and non-RoHS status (note for legacy or exempted applications).
