  • EMI suppression device
    Patent number: 7038899
    Abstract: An electromagnetic interference (EMI) suppression device includes a case, a common mode noise reduction element, a plurality of conductive pillars and at least one differential mode noise reduction element. The case includes a housing that can accommodate the common mode noise reduction element and a plurality of foot portions that protrude from the housing. A plurality of conductive pillars penetrate the case to form two separate portions, a mount for receiving differential mode noise reduction elements and a connection pad, and the EMI suppression device is mounted onto a printed circuit board via the connection pad.
    Type: Grant
    Filed: July 9, 2003
    Date of Patent: May 2, 2006
    Assignee: Delta Electronics, Inc.
    Inventors: Han-cheng Hsu, Wen-te Ko
  • Filtering induction device
    Patent number: 7026903
    Abstract: A filtering induction device is provided to improve the filter effect via the increase of an insertion loss resulting from stray capacitance. The induction device includes at least one core structure, and first and second flat coils that interlacing with each other. The first flat coil is used as an inductor, and the second flat coil is used as an electrode belonging to a capacitor formed between the circles of the first flat coil.
