PCN SERIES

Product catalog summary

Overview: The document provides detailed specifications and options for PCN series composition resistors, highlighting their high energy and voltage capabilities, non-inductive nature, and wide range of applications. These resistors are made from carbon and ceramic granules, offering pulse capabilities superior to wirewound or film resistors.

Specifications: PCN resistors come with standard tolerances of 10% and 20%, with 5% available. They can be customized in rod or disk sizes up to 5” in diameter and 18” long. The resistors are suitable for applications such as snubber circuits, lightning surge, grounding resistors, RFI suppression, and dummy loads. They comply with various standards including UL, IEEE, and EN.

Performance: The resistors have a maximum continuous voltage determined by the formula E= (PR)1/2, not exceeding the maximum working voltage. Peak pulse voltage and joule ratings depend on resistance, pulse waveform, and duration. Expanded resistance ranges and increased ratings are available upon consultation.

Options: Options include special coatings for oil immersion, Group A screening per Mil-R-39008, custom sizes, expanded resistance ranges, and increased voltage/dielectric/joule ratings. End caps, lug terminals, and mounting clips are also available.

Derating and Temperature: The resistors are designed to operate within a temperature range of -55°C to +125°C, with some models extending to +230°C. Derating is applied based on ambient temperature, with specific guidelines provided for different temperature ranges.

Figures and Diagrams: The document includes diagrams illustrating axial lead, surface mount, and rod configurations, along with a derating curve showing the relationship between ambient temperature and rated power.

Part Number Designation: The part number system includes codes for RCD type, options, tolerance, packaging, resistance, and termination. The resistors are RoHS compliant and compatible with 260°C.
