Product Overview
The RCR series are discharge path resistors, specifically designed as surge-resistant, insulated fixed resistors with excellent surge characteristics and stable performance across a wide resistance range, even in high humidity environments. These resistors are suitable for automatic surface mounting and are used in applications such as TVs, copiers, LBP, switching power supplies, and AC adapters. Certain models are certified to UL1676, c-UL (CSA-C22.2 No.1-M94) discharge resistor standards and EN62368-1 G.10 standards. They comply with EU RoHS directives, with lead in glass exempt from RoHS. These resistors are designed for high voltage applications.
