ORNTA1002AT3

ORNTA1002AT3 Description

The ORNTA1002AT3 from Vishay is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 8-pin SOIC packaged device features four isolated 10 kΩ resistors with an exceptional ±0.1% tolerance and a low ±25 ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (-55°C to +125°C). With a 0.4W total power rating (100 mW per resistor) and a 100V maximum voltage rating, it is ideal for precision analog circuits requiring tight resistance matching and minimal drift. The molded, gull-wing termination design enhances reliability in automated assembly processes, while compliance with EU RoHS standards ensures environmental safety.

ORNTA1002AT3 Features

• Precision Thin Film Technology: Delivers ±0.1% tolerance and ±25 ppm/°C TCR for ultra-stable performance.
• Isolated Circuit Design (ISOL): Four independent resistors minimize crosstalk in high-impedance applications.
• Robust Construction: Molded SOIC package with 1.27 mm terminal pitch ensures mechanical durability and ease of soldering.
• Wide Operating Range: Functions reliably from -55°C to +125°C, with derated power up to 150°C.
• Surface-Mount Compatibility: Gull-wing leads facilitate high-speed PCB assembly (tape-and-reel packaging available).
• Low Power Dissipation: 100 mW per resistor (400 mW total) balances performance with thermal management.

ORNTA1002AT3 Applications

This resistor network excels in precision instrumentation, medical devices, and industrial control systems where low drift and high accuracy are critical. Key applications include:

• Analog signal conditioning (DAC/ADC reference dividers, gain networks).
• Feedback networks in op-amp circuits and voltage regulators.
• Sensor calibration (strain gauges, RTDs, and bridge circuits).
• Test & measurement equipment requiring matched resistance values.
• Automotive and aerospace electronics (excluding safety-critical systems, as it is not PPAP/AEC-Q200 qualified).

Conclusion of ORNTA1002AT3

The ORNTA1002AT3 stands out for its exceptional precision, isolation, and thermal stability, making it a superior choice over standard thick-film networks. Its compact SOIC-8 footprint, thin-film construction, and tight tolerances cater to high-reliability designs in industrial, medical, and test equipment. While not automotive-grade, its RoHS compliance and robust performance ensure suitability for commercial and professional applications demanding long-term accuracy. Engineers seeking low-drift, high-density resistor networks will find this Vishay model an optimal solution.
