Abstract
A chip type choke coil component comprises a coil 11 wound from insulated conductive wire 112. The insulation at each end portion 111 of the wire is removed to form respective terminals and a core 12 of fixed length is arranged to closely comply with the insulated conductor coil 11 to provide coil components with various different effective number of turns. The insulated conductive wire 112 comprises a conductive core 113 with an insulating coating 114, each of which may have various cross sectional shapes (square, circular, rectangular, or elliptical) and/or dimensions to influence the resulting componentâ s operational characteristics. The length of the wire ends used in forming terminals 111 may be varied to modify the said characteristics. The core 12 width and height and that of the corresponding coil 11 may be varied. The core 12 may include an elongate member with a square cross section with curved surfaces forming fillet regions such that the core can be easily inserted into a coil 11 in a close, friction fitting manner and the core material may be varied. The chip coil component arrangements may provide adaptable, easy to use, miniature, high frequency components with at least one fixed dimension and different operational characteristics.
