Y5U is generally used in high temperature products. Y5V is generally more than 1000PF capacity of normal material
The temperature characteristics of each safety capacitor are different, and the corresponding temperature change rate is also different at the class temperature.
Y capacitor Y5U,Y5V,Y5P respectively represent E characteristic, F characteristic, B characteristic material.
It refers to the temperature range of -25 degrees ~ +125 degrees, the temperature change rate of different materials is different, so in different environments to use the same product on the material requirements are not the same. Different products require different materials.
Y5V&Z5U Material series
Y5V (2F4)(Z5U): the third type of dielectric, with high dielectric constant, is often used for the production of large specific capacity, high nominal capacity of safety capacitor products, but its capacity stability is worse than X7R, capacity, loss is sensitive to temperature, voltage and other test conditions.
Temperature characteristic: -30° to 85° -82% < Tolerance change < +22% Aging characteristic 5% for 10 years
Y5U, Y5V and Y5P are ceramic capacitors and belong to Class III, with an effective operating temperature range of -30~+85℃, but can be further subdivided into different grades.
The temperature compensation performance of Y5P is the best, the capacitance variation range of the whole temperature range is ±10%.
Y5U is not compensable for temperature changes, and the capacitance range is +22%/-56% over the full temperature range.
Y5V is not compensable for temperature changes, and the capacitance range is +30%/-80% over the full temperature range.
NPO (COG): A Class of dielectric (class-1), the most stable electrical performance, basically does not change with the change of temperature, voltage and time, suitable for high stability requirements of safety capacitor. In fact, we often talk about precision capacitance, is this kind, because the capacitance of other materials with a large error with temperature change.
NPO material safety capacitance temperature characteristic and 55 ° ~ + 125 ° | | capacitance values change < 30 PPM / ° C for one over one million (PPM).
>> X7R material series
X7R (2X1): a second-class dielectric with stable electrical performance and no significant change in performance when temperature, voltage and time change. It is suitable for the full frequency discrimination circuit with separate, coupling bypass and low requirement for capacity stability. Because X7R is a strong dielectric, it is possible to build a larger capacitance than the NPO medium.
X7R material condenser temperature characteristic and 55 ° ~ + 125 ° | | capacitance values change < 10 years was less than 1% 15% aging characteristics
Safety capacitor material
X5R material series
X5R: Type II dielectric, similar to X7R
