KYOTO, Japan--(BUSINESS WIRE)--Murata Manufacturing Co., Ltd. (TOKYO:6981) (ISIN:JP3914400001) has launched a surface mount type IEC 60384-14*1 Y1*2 class safety certified ceramic capacitor for low-profile power supplies. This capacitor is ideal for all AC-DC switching power supplies where a low-profile is sought for compact AV equipment, LED illumination, or 1U*3 rack mounted equipment.
Detail
Safety certified capacitors are placed at a power
line input side in order to eliminate noise that builds up primarily in
commercial AC power lines.
Safety certified capacitors are usually
of the lead type, but the mounted height above the board surface is a
problem because it hinders efforts to make low-profile devices and it
limits component layout. In addition, because lead type capacitors are
through-hole mounted, the lead wires are exposed on the underside of the
circuit board. A fixed amount of insulating distance between the exposed
lead wires and the metal components of the device is required by safety
standards, so this complicates spatial layout within a device. The new
Murata capacitor uses a structure of plate-shaped terminals on a
disc-shaped ceramic dielectric placed within a plastic mold to reduce
the terminal thickness that is present with lead type capacitors, and
this results in a mounted height of 2.5mm or less for the product.
Furthermore, the component format enables reflow surface mount, and
there is no longer a need to assure insulating distance at the underside
of the board. This advances profile reduction for power supply devices
subject to size limitations in compact AV equipment, LED illumination
and 1U rack mounted equipment, for which spatial design has been
difficult.

Explanation of terms |

*1. IEC 60384-14: | An international standard that regulates the withstanding pressure and combustion resistance of capacitors connected to commercial power supplies, from the standpoint of preventing fires and electric shock from electrical leakage. | |
*2. Y1: | A subclass of capacitors classified by insulation type in the standard mentioned above. Y1 subclass capacitors have the highest performance requirements. | |
*3. 1U: | A unit that expresses the height of a device such as a server or storage unit that is stored in a 19 inch rack placed in a data center or other location. A device with a height equivalent to a single stage is said to have height of 1U, and a device with height equivalent to two stages has a height of 2U. The height of 1U is generally held to be “1U = 1.75 inch” by the computer industry related Electronic Industries Alliance (EIA). | |
