The present invention relates to a circuit protection device and a method of manufacturing the same. The circuit protection device includes a common mode noise filter having a plurality of sheets, each of the sheets being formed to optionally include a coil pattern, an internal electrode, a hole filled with a conductive material, and a hole filled with a magnetic material; and an electrostatic discharge (ESD) protection device having a plurality of sheets, each of the sheets being formed to optionally include an internal electrode and a hole filled with an ESD protection material.

Circuit protection device and method of manufacturing the same

Provided is an electromagnetic interference shielding gasket, which includes an elastomer, a soldering prevention part disposed in at least one region of a side surface and a bottom surface of the elastomer, and an electrode disposed on the bottom surface of the elastomer. Even when solder cream for attaching the EMI shielding gasket to a printed circuit board is pushed from the bottom surface of the EMI shielding gasket by its surface tension and solder-rising, the solder cream stays in the soldering prevention part without moving upward along the side surface of the EMI shielding gasket. Accordingly, the reliability of soldering can be ensured without sacrificing elastic resilient force of the EMI shielding gasket.

EMI shielding gasket

Provided is an electromagnetic interference shielding gasket including an elastomer, and an electrode partially inserted and fixed in the elastomer, and bent along a side surface and a bottom surface of the elastomer. The electrode may be fixed through an adhesive tape to the bottom surface of the elastomer. Coupling force between the elastomer and the electrode is improved, and thus, a removal of the elastomer from the electrode after a mounting process is prevented.

In one embodiment, a circuit protection device includes a common mode noise filter having a plurality of sheets, each of the sheets being formed to optionally include a coil pattern, an internal electrode, a hole filled with a conductive material, and a hole filled with a magnetic material; and an electrostatic discharge (ESD) protection device having a plurality of sheets, each of the sheets being formed to optionally include an internal electrode and a hole filled with an ESD protection material.

The present invention relates to piezoelectric vibrators such as a resonator used as a timing element, discriminator, filter or the like, and fabricating methods thereof. The piezoelectric vibrators of the present invention may be fabricated by forming a piezoelectric body of piezoelectric sheets, of which the thickness is controlled, and simultaneously sintering the sheets along with cover layers, on which grooves are formed. Also, the piezoelectric vibrator of the present invention is fabricated by laminating the piezoelectric sheets, of which the thickness is controlled, providing internal electrodes between the sheets, and forming external electrodes insulated from the internal electrodes.

Piezoelectric vibrator and fabricating method thereof

The invention relates to a low inductance multilayer chip and a method for fabricating the same, the multilayer chip including a plurality of internal electrode layers where the internal electrodes of the predetermined layers are electrically connected to reverse the current directions flowing in the internal electrodes of neighboring layers to thereby offset inductance and performing stable operations at high frequency.
