Chip Inductors – 0402CS (1005)
Continuing in our long tradition of innovation and lead-
ership, 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.
