CECC40201-002KB – TBC

The CECC40201-002KB is a wirewound resistor conforming to a CECC 40201 style specification, indicating a standardized European component. The “W21” likely refers to the winding configuration or a specific manufacturing process within the unknown manufacturer’s internal designation, but without further documentation, its exact significance is indeterminate. The resistor has a nominal resistance value of 1.0 Ohm (1R0) with a tolerance of ±5%. Given the “WW” designation, the resistor is constructed using a wirewound element, suggesting suitability for applications requiring higher power dissipation or pulse handling capabilities compared to film resistors. The RoHS status is currently unknown, requiring verification to ensure compliance with Restriction of Hazardous Substances directives for applications within applicable jurisdictions. The absence of a known manufacturer necessitates careful consideration regarding sourcing and reliability, potentially requiring independent testing to validate performance characteristics.
