ORNA1002ZT5

ORNA1002ZT5 Description

The ORNA1002ZT5 from Vishay is a high-precision thin-film resistor network designed for demanding surface-mount (SMD) applications. This 4-resistor isolated network features a 10 kΩ resistance per element with an ultra-tight ±0.1% tolerance and a low ±25 ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +150°C derated power range. Encased in a molded epoxy SOIC-8 package with gull-wing leads, it offers 0.4W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it ideal for precision analog and digital circuits. Packaged in tape and reel (T/R), it supports automated assembly processes.

ORNA1002ZT5 Features

• High Precision: 0.1% tolerance and ±25 ppm/°C TCR for stable performance in temperature-sensitive applications.
• Robust Construction: Molded epoxy case ensures durability and moisture resistance.
• Isolated Design: 4 independent resistors in an 8-pin SOIC, allowing flexible circuit integration.
• Surface-Mount Ready: Gull-wing termination (1.27mm pitch) for reliable PCB soldering.
• Wide Operating Range: -70°C to +150°C (derated) and 125°C maximum continuous operating temperature.
• Thin-Film Technology: Delivers low noise and high stability compared to thick-film alternatives.

ORNA1002ZT5 Applications

This resistor network excels in precision instrumentation, medical devices, industrial control systems, and automotive electronics (though not PPAP/automotive-qualified). Its low TCR and tight tolerance make it ideal for:

• Voltage dividers and sensor calibration circuits.
• ADC/DAC reference networks requiring minimal drift.
• Signal conditioning in test/measurement equipment.
• Isolated feedback networks in power supplies.

Conclusion of ORNA1002ZT5

The ORNA1002ZT5 stands out for its exceptional accuracy, thermal stability, and compact SOIC-8 footprint, making it a superior choice for engineers prioritizing long-term reliability in precision analog designs. While not RoHS-compliant, its thin-film construction and isolated resistor configuration offer performance advantages over standard arrays, particularly in high-accuracy DC and low-frequency applications. For space-constrained, high-reliability systems, this Vishay network delivers consistent results under varying environmental conditions.
