20120025930 | PROGRAMMABLE ANTIFUSE MATRIX FOR MODULE DECOUPLING - An adapter couples a module to a circuit board. The adapter comprises a decoupling capacitor, which has a first capacitor plate and a second capacitor plate separated by an insulating dielectric, located within the adapter. A voltage pin and a ground pin within the adapter traverse through the decoupling capacitor in order to make voltage and ground connections between the module and the circuit board. A first fusible ring, which is adjacent to the first capacitor plate, encircles the voltage pin, and a second fusible ring, which is adjacent to the second capacitor plate, encircles the ground pin. When the first and second fusible rings are fused to their respective capacitor plates, the decoupling capacitor provides the module with decoupling capacitance protection from stray alternating current voltage, and also provides the module with power/ground sources to compensate for current/ground spikes. | 02-02-2012 |
20120188742 | IMPLEMENTING SURFACE MOUNT COMPONENTS WITH SYMMETRIC REFERENCE BALANCE - A method and structure are provided for implementing surface mount components with symmetric reference balance. A first reference and an incoming signal are received in a surface mounted device (SMD) package and a second reference and the outgoing signal are output from the SMD package. A capacitor structure is defined within the SMD package between the first reference and the second reference. The capacitor structure includes a balanced impedance structure between the first reference and the second reference. A component connected between the received incoming signal and output signal is generally centrally located within the capacitor structure. | 07-26-2012 |
20130048371 | IMPLEMENTING ADJUSTABLE SIZE FERRITE CORE FOR EMI CABLE NOISE SUPPRESSION - A method and structures for implementing an adjustable size ferrite core for electromagnetic interference (EMI) cable noise suppression. A plurality of ferrite core segments are mated together defining an adjustable size cable receiving cavity. Each of the ferrite core segments includes an inner wall portion with mating fingers extending along adjoining edges. The mating fingers are selectively positioned together to select a size of the adjustable cable receiving cavity. | 02-28-2013 |
20130333928 | IMPLEMENTING FEED-THROUGH AND DOMAIN ISOLATION USING FERRITE AND CONTAINMENT BARRIERS - Methods and structures are provided for implementing feed-through and domain isolation using ferrite and containment barriers. A vertical isolator is provided between a first domain and a second domain on a printed circuit board with signals passing between the first domain and the second domain. The vertical isolator is placed over a domain separation gap between the first and second domains in the printed circuit board, the vertical isolator having a vertical isolation barrier between a first vertical plate coupled to the first domain and a second vertical plate coupled to the second domain. The vertical isolation barrier is formed of a unitary ferrite block or a non-conductive magnetic absorber material. A plurality of capacitance feed-through plates and a dielectric material are provided within the vertical isolator. | 12-19-2013 |
