Overview
Murata Manufacturing Co., Ltd. has launched a surface mount type IEC 60384-14*1 Y1*2class 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. The mass production of the capacitor began in May 2017.
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.Electrical characteristics

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).
