High-Q RF Wirewound Chip Inductors
These high-frequency, high-Q chip inductors feature a monolithic ceramic or ferrite body wound with wire for optimal performance. They are compact and supplied on tape and reel, making them ideal for high-volume RF applications. Ceramic core types (0402, 0603, and most 0805) have a nickel barrier with gold plating, while ferrite core types (0805 size, 470 nH and higher) feature 100% tin plating. Most inductance values between those listed are available upon request.
