ORNA5000BT1

ORNA5000BT1 Description

The ORNA5000BT1 from Vishay is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-pin SOIC (Small Outline Integrated Circuit) device features four isolated 500Ω resistors with an exceptional tolerance of ±0.1% and a low temperature coefficient of ±25ppm/°C, ensuring stable performance across a wide operating temperature range of -55°C to +125°C. The molded epoxy case provides robust protection, while the gull-wing termination enables reliable surface-mount (SMD) assembly. Packaged in tape and reel (T/R), it is optimized for automated PCB production. With a maximum voltage rating of 100V and a total power dissipation of 0.4W (0.1W per resistor), this network is ideal for precision analog and digital circuits.
