ORNA1003ZT5

ORNA1003ZT5 Description

The ORNA1003ZT5 from Vishay is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 4-resistor isolated network features a 100K Ohm resistance value with an exceptional 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Housed in an 8-pin SOIC package with gull-wing terminations, it offers 0.4W total power dissipation (0.1W per resistor) and operates reliably within a -55°C to +125°C range, derating up to 150°C. Its molded construction enhances durability, while the 100V maximum voltage rating makes it suitable for high-voltage isolation circuits.

ORNA1003ZT5 Features

• Precision Performance: Ultra-tight 0.1% tolerance and ±25ppm/°C TCR for stable operation in critical circuits.
• Robust Construction: Molded SOIC package ensures mechanical strength and thermal stability.
• High Power Handling: 0.4W total (0.1W per resistor) with derating up to 150°C.
• Isolated Design: 4-resistor network (ISOL circuit) for independent signal paths, reducing crosstalk.
• Surface-Mount Ready: Gull-wing terminals with 1.27mm pitch for easy PCB integration.
• Medical & Industrial Grade: Suitable for harsh environments, though non-automotive (PPAP: No).
