ORNA5-1T5

ORNA5-1T5 Description

The ORNA5-1T5 by Vishay is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerance and stability. Housed in an 8-pin SOIC package with gull-wing termination, this 4-resistor network features a 10KΩ/2KΩ resistance ratio with an exceptional ±0.1% tolerance and a low ±25ppm/°C temperature coefficient. Its molded epoxy construction ensures durability, while the surface-mount (SMD) design facilitates compact PCB integration. With a 0.4W total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a -55°C to +125°C range, derating up to 150°C. Packaged in tape and reel (T/R), it is optimized for automated assembly.
