Wire-wound inductance Wide range of inductance (mH~H), high inductance precision, low loss, low cost; Compared with the winding inductor, the laminated inductor is small in size, the magnetic circuit is closed, and will not interfere with the surrounding components. The laminated integrated structure, high reliability, good heat resistance, good weldability, and regular shape are suitable for automatic surface installation and production. The shortcomings are high cost and small inductance.
The difference is that the heat dissipation of the laminated layer is better, and the ESR value is smaller. But the current resistance is smaller than the winding. The heat dissipation of the winding is not as good as that of the lamination, and the ESR value is higher, but the current resistance will be greater.
In general, laminated inductors are not visible linesThe laminated inductor has good heat dissipation and smaller ESR value, but the current resistance is smaller than that of the wound inductor. Lower cost than wound inductors. The heat dissipation of wound inductors is not as good as that of laminated inductors, but the current resistance is large and the ESR value is higher.
First of all, when laminated inductors are used instead of wound inductors, the parameters of laminated inductors are better and higher than those of wound inductors. Secondly, pay attention to the difference between laminated inductors and wound inductors. The difference between laminated inductors and wound inductors is that the laminated inductors have better heat dissipation and lower ESR value. But the current resistance is smaller than the winding. The heat dissipation of the winding is not as good as that of the lamination, and the ESR value is higher, but the current resistance will be greater.
1, X7R lamination accuracy : It is a strong dielectric lamination accuracy , so it can manufacture capacitors with greater capacity lamination accuracy than NPO media. X5R: has a high dielectric constant lamination accuracy , often used in the production of specific volumeLarge capacity capacitor products with high nominal capacity. The chip capacitor has two dimensional representation methods, one is expressed in inches, and the other is expressed in millimeters.
2, X5R: has a high dielectric constant, often used in the production of large capacity capacitors with large specific capacity and high nominal capacity. Application Different X7R: The performance of the capacitor is relatively stable, with the change of temperature and voltage time, its unique performance change is not significant, belongs to the type of stable capacitor material, used in the straight separation, coupling, by-pass, filter circuit and high reliability requirements of the high frequency circuit.
3,X5R, X7R and X7S all refer to the filling material characteristics of ceramic capacitors, which are common to all capacitor manufacturers. The X7R capacitor is known as a temperature-stable ceramic capacitor. When the temperature is -55℃ to 125℃, its capacity changes by 15%, and the capacity is moderately lower. X5R This material capacity can be made larger, capacitive stability can also be, suitable for making large capacity capacitors, suitable for making large capacity capacitors. X7S is generally used to withstand relatively high voltage capacitors.
4, X5R and X7R temperature coefficient /-15%. The chip capacitance temperature coefficient refers to the unit temperature within a certain ambient temperature rangeThe influence of degree change on capacitor capacity change. There are two kinds of temperature coefficients. The capacitance of a capacitor with a positive temperature coefficient increases with the increase of temperature, whereas the capacitance of a capacitor with a negative temperature coefficient decreases with the increase of temperature. The lower the temperature coefficient, the more stable the capacitor.
