Document 198-1 Chip Inductors – 0402CS Series (1005) Continuing in our long tradition of innovation and leadership, Coilcraft introduced the industry’s first 0402 wirewound inductor. This series shares all of the characteristics of Coilcraft’s other ceramic inductors: exceptionally high Q factors, especially at use frequencies; outstanding self-resonant frequency; tight inductance tolerance; and excellent batch-to-batch consistency.
