GQ0A027872FAT

GQ0A027872FAT Description

The GQ0A027872FAT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package integrates 10 isolated resistors, each with a 78.7KΩ resistance, 1% tolerance, and a ±50ppm/°C temperature coefficient. Encased in a ceramic substrate, it ensures superior thermal stability and durability. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a 70°C to 125°C derated power range, peaking at 125°C. Its gull-wing termination and 0.64mm pitch facilitate seamless surface-mount assembly, while the rectangular QSOP package (8.66mm x 6.02mm x 1.47mm) optimizes PCB space.

GQ0A027872FAT Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical circuits.
• Isolated Resistors (ISOL): Independent 78.7KΩ resistors minimize crosstalk in multi-channel designs.
• Ceramic Case: Enhances thermal dissipation and mechanical robustness.
• 1% Tolerance & ±50ppm/°C TCR: Ensures consistent performance under thermal stress.
• High Power Density: 1W total dissipation (0.1W/resistor) in a compact QSOP footprint.
• Gull-Wing SMD Termination: Simplifies automated PCB assembly.
• Wide Operating Range: -55°C to +125°C (full power up to 70°C).

GQ0A027872FAT Applications

Ideal for precision analog circuits, medical instrumentation, and industrial control systems where stability and isolation are critical. Its low TCR and tight tolerance make it suitable for:

• Voltage dividers in sensor interfaces.
• Feedback networks in op-amp circuits.
• Signal conditioning in data acquisition systems.
• Isolation barriers in communication modules.
  The non-automotive (PPAP No) and non-RoHS compliance may limit use in consumer electronics but aligns with niche industrial or legacy designs.

Conclusion of GQ0A027872FAT

The GQ0A027872FAT excels in high-reliability applications demanding precision, thermal resilience, and compact integration. Its ceramic thin-film construction, isolated resistor design, and QSOP packaging offer a competitive edge over polymer-based networks or lower-tolerance arrays. While unsuitable for automotive or RoHS-regulated projects, it remains a top choice for mission-critical analog systems requiring long-term stability. Engineers should verify unconfirmed part status with TT Electronics for production readiness.
