Panasonic will start mass production of the new power choke coil October 2013, with a monthly production capacity of 7 million pieces.
Features of the New Power Choke Coil for Automotive Applications
When disconnecting the inverter, the energy, stored in the choke coils, returns to the condensers of the filter of the power rectifier, bypassing the primary circuit of the TRM.
Innovative wire-winding and production techniques produce 1210 case size choke coils with 8GHz cut-off for common-mode noise reduction in flat-screen TVs and other high-definition applications
However, reducing the size of the wire-wound inductor (functioning as a choke coil to prevent or limit AC while allowing DC to flow) increases resistance and reduces the efficiency of the DC-DC converter.
Using new precise winding technology Murata can deliver a low cost common mode choke coil that meets the performance needs of Universal Serial Bus (USB), FireWire/IEEE 1394, Low-Voltage Differential Signaling (LVDS) and other high-speed digital interfaces.
The second series, DLP31D is also small (1206 size), but utilizes Murata's innovative Film Technology to produce a two-pair common mode choke coil array.
The new high-speed interfaces such as IEEE1394 (Firewire), USB, and LVDS are ideal for this surface mount common mode choke coil.
He concluded, “IndustrialCOOP recently added new lines of power supply systems and equipment to its directory in effort to bring users a broader range of energy savings solutions such as connectors, receptacles, lithium polymer & lithium ion battery charger, circuit breakers, electrical supplies, AC & DC outputs, AC, DC & surge protected power supplies, cable knock-outs, choke coils, fuses, transformer shelf & load center as well as various types of generators such as gas, natural gas, diesel and LPG.
Toko's products include voltage regulators, choke coils, inductors, inverters and converters, white LED drivers, LC and other filters interface modules, and wireless LAN modules.
Murata offers a variety of coils, including choke coils with low DC resistance intended for power supply circuits, general-purpose chip coils suitable for voltage increases, and high-frequency chip coils that provide low-loss and high-Q characteristics at high-frequencies.
The contract is the purchase of equipment (case cylindrical winding machine, a toroidal winding machine, with guide microplasma, vacuum pressure impregnation station, electric furnace, a test device for an output choke apparatus for testing / control characteristics (inductance) choke coils depending on the frequency, used for precision cutting coiled sheet tester) and put them into production.

Equivalent Size Parts -- Ideal for DC-DC Converter Choke Coils in Ultra-Thin Portable Electronics
Consequently, strong demands are being made on choke coils to provide higher rated current, take up less PCB real estate, and stay under the component height limits imposed by other essential ICs.
