OU & OUM Film Ceramic Resistors

Ohmite OU and OUM Film Ceramic Resistors are cost-effective composite film resistors suitable for replacing ceramic composition resistors, which are required in many pulse applications. These resistors are available in through-hole axial or SMD MELF package types to suit different board designs. Both kinds of resistors have 1W power ratings, 15KV maximum permissible surge voltage, 33Ω to 22KΩ resistance range, ±10%, ±20% resistance tolerance, and E-6 / E-12 available resistance ratings. The OU resistor has a 300V maximum working voltage, and the OUM resistor has a 400V maximum working voltage. Ohmite OU and OUM Film Ceramic Resistors conform to ANSI/AAMI EC53:2013/ IEC 60601-2-27:2011.
