Kyocera said it succeeded in developing the new CU02 series 01005 size multilayer ceramic capacitor (MLCCMultiple-layer capacitors interleave dielectric and electrode layers. This type of capacitor has increased current handling capacity, higher Q, and lower internal series resistance than conventional capacitors of the same size and capacitance.) with the world’s highest Q value in the high-frequencyThe number of complete cycles or vibrations per unit of time. Rate of alternation in an AC current. Expressed in cycles per second or hertz (Hz). band, for power amplifier circuits mainly used in smartphones and other telecommunications equipment.
The company started mass production of the new series this month.
Main Features as explained by Kyocera:
1. 01005 Size MLCCMultiple-layer capacitors interleave dielectric and electrode layers. This type of capacitor has increased current handling capacity, higher Q, and lower internal series resistance than conventional capacitors of the same size and capacitance. with world’s highest Q value
The development of this product focused on improving the Q value in the high-frequencyThe number of complete cycles or vibrations per unit of time. Rate of alternation in an AC current. Expressed in cycles per second or hertz (Hz). band (GHz band) used specifically for wireless communications. In the measurement of 01005 size MLCCs with capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. of 4pF and at a frequencyThe number of complete cycles or vibrations per unit of time. Rate of alternation in an AC current. Expressed in cycles per second or hertz (Hz). of 1GHz, the Q value has been improved roughly threefold compared with the company’s conventional products, to approximately 290, realizing the world’s highest value.
2. Broad product lineup with capacitances between 0.2 to 22pF, supporting a wide range of design specifications
To improve impedanceThe total opposition that a circuit offers to the flow of alternating current or any other varying current at a particular frequencyThe number of complete cycles or vibrations per unit of time. Rate of alternation in an AC current. Expressed in cycles per second or hertz (Hz).. It is a combination of resistance R and reactance X, measured in ohms. mismatches in high-frequencyThe number of complete cycles or vibrations per unit of time. Rate of alternation in an AC current. Expressed in cycles per second or hertz (Hz). circuits including power amplifiers for radio transmission, there is a need for the precise adjustment of impedances. This requires MLCCs with highly accurate, finely and evenly distributed capacitances. To meet this requirement, Kyocera offers a product lineup with capacitances between 0.2 to 22pF, with products in 0.1pF intervals for those with capacitances in the range of 0.2 to 10pF commonly used for circuit matching.
