GQ0A028451DAT

GQ0A028451DAT Description

The GQ0A028451DAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP package features 10 isolated resistors, each with a 8.45KΩ resistance and a tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case style and gull-wing termination provide robust mechanical stability and reliable surface-mount compatibility. With a ±50ppm/°C temperature coefficient, this network maintains stable performance across a wide operating range of 70°C to 125°C, making it suitable for environments with thermal fluctuations.

GQ0A028451DAT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• High Power Handling: 1W total power rating (0.1W per resistor) with a 100V maximum voltage rating, ideal for power distribution networks.
• Compact & Robust Design: 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances ensure consistent PCB integration.
• Isolated Resistors (ISOL): Independent resistors reduce crosstalk, critical for multi-channel systems.
• Wide Temperature Range: Operates reliably up to 125°C, suited for industrial and automotive-adjacent applications (though not PPAP/automotive certified).
• QSOP Package: 0.64mm terminal pitch enables high-density board layouts.

GQ0A028451DAT Applications

• Signal Processing: Precision voltage dividers in ADC/DAC circuits.
• Medical Electronics: Isolation networks in patient monitoring equipment.
• Test & Measurement: Calibration resistors for lab instruments requiring low drift.
• Industrial Controls: Feedback networks in motor drives or power supplies.
• Communications: Impedance matching in RF modules (non-RoHS compliant; verify environmental regulations).

Conclusion of GQ0A028451DAT

The GQ0A028451DAT excels in applications demanding high precision, thermal stability, and compact form factors. Its isolated thin-film resistors, tight tolerances, and robust ceramic construction distinguish it from generic arrays, though designers should note its non-RoHS compliance and unconfirmed status for critical projects. Ideal for engineers prioritizing accuracy in harsh environments, this network balances performance with practical SMD manufacturability.
