ORNTA2003AT1

ORNTA2003AT1 Description

The ORNTA2003AT1 from Vishay is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 4-resistor ISOL (isolated) configuration offers a 200K Ohm resistance per element with an ultra-tight 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -55°C to +125°C. Housed in an 8-pin SOIC package with gull-wing terminations, it features a molded epoxy case for durability and reliable performance in harsh environments. Compliant with EU RoHS, it is supplied in tape and reel (T/R) packaging for automated assembly efficiency.

ORNTA2003AT1 Features

• Precision Performance: 0.1% tolerance and ±25ppm/°C TCR for critical analog/digital signal conditioning.
• Robust Construction: Molded epoxy case enhances mechanical strength and moisture resistance.
• High Voltage Handling: Supports up to 100V maximum voltage rating per resistor.
• Power Efficiency: 0.4W total power rating (0.1W per resistor) with derating up to 150°C.
• Compact & Reliable: 4.9mm x 6mm footprint and 1.55mm profile ideal for space-constrained PCBs.
• Automation-Ready: Gull-wing terminations and 1.27mm pitch ensure compatibility with pick-and-place systems.

ORNTA2003AT1 Applications

• Precision Instrumentation: Used in medical devices, test equipment, and data acquisition systems where accuracy is paramount.
• Industrial Controls: Ideal for PLC modules, sensor interfaces, and feedback networks due to its stability under thermal stress.
• Communication Systems: Enhances signal integrity in RF amplifiers, filters, and ADC/DAC circuits.
• Automotive & Aerospace (non-AECQ): Suitable for avionics and industrial-grade automotive subsystems (non-PPAP).

Conclusion of ORNTA2003AT1

The ORNTA2003AT1 stands out for its exceptional precision, compact form factor, and rugged epoxy encapsulation, making it a superior choice over generic thick-film networks. Its low TCR and high voltage tolerance cater to mission-critical designs, while the SOIC-8 package ensures broad compatibility. Engineers seeking long-term reliability in harsh environments will find this resistor network indispensable for high-accuracy analog circuits and industrial electronics.
