Introducing the Eaton Electronics Coupled Inductors with part number CTX20-1A-R. Designed for high-performance electronic applications, these inductors are RoHS compliant and manufactured in China (COO: CN). Packaged on a reel for efficient surface-mount assembly, they are ideal for use in power conversion, noise filtering, and isolation applications.
Key Features
High-quality surface mount magnetics suitable as single or coupled inductors or 1:1 transformers providing electrical isolation between windings
Constructed around high-frequency, low-loss core materials for optimal performance
Versatile inductance configurations via series or parallel connections
Secure 4-terminal mounting for reliable installation
