x5r vs x7r

The main material is different media. Depending on the main polarization type of different media, the response speed and polarization rate of the electric field change are not the same. The capacity of the same volume is different, and the resulting capacitor dielectric loss, capacity stability and so on are different. Dielectric material in the capacity of the temperature stability can be divided into two categories, namely, Ⅰ class ceramic capacitors and Ⅱ class ceramic capacitors, NPO belongs

last year's Skylake six Daicouri processor release, Intel launched a 100-series chipset for the new LGA1151 interface, which is the H/B/Z 100 system motherboard. Kaby Lake Processor Although this year's Kaby Lake desktop processor does not change the interface, that is, the 100-series motherboard can still be upgraded seamlessly, but in order to fit its Optane nonvolatile storage technology (based on its solid-state hard disk, memory is also the end of this year and early next yea

temperature, and the capacity of some capacitors decreases by more than 70% when the temperature increases. The commonly used filter capacitor is the porcelain medium capacitor. Porcelain capacitor has three types: Ultra-stable (such as cog or NPO), stable (such as X7R), and general (such as Y5V or z5u. The Temperature Characteristics of capacitors of different media are shown in 4-9. From Figure 4-9, we can see that the capacity of the cog capacit

It is inSome ceramic film billet are covered with electrode Propeller Material, and then merged into an integral whole.,Encapsulated with Resin. It has the advantages of small size, large capacity, high Q value, high reliability and high temperature resistance. It also has the disadvantages of large capacity error and high temperature coefficient. It is generally

. Variable CapacitanceIt is composed of a group of fixed and a group of dynamic parts. Its capacity can change continuously with the rotation of the dynamic part. The two sets of variable capacitors are mounted together for coaxial rotation, which is called dual-connection. The variable capacitor has two kinds of media: Air and polystyrene. The variable capacitance of the air medium is large in size and has low loss. It is used in electronic tube radio. The Polystyrene medium variable capac

fknee is far greater than fbypass, and the serial inductance of 5nh is definitely not good. Computing:Ltot = xmax/(2PI × fknee) = (xmax × TR/PI) = 19.7ph;As mentioned above, the serial inductance of the common SMD capacitor is around 1.5nh, and the number of capacitors required is:N = (lserial/ltot) = 76. In addition, when the frequency drops to fbypass, it should also meet the board-level anti-DDoS requirements:Carray = (1/(2PI × fbypass × xmax) = 5.23 UF;Celement = carray/N = 69nf;Wow, it's r

Generally, the SMD capacitor refers to MLCC, that is, multilayer ceramic capacitors, also known as chip capacitor or chip capacity. Conventional SMD capacitors are divided into cog (NPO), X7R, Y5V, according to the imperial standard, their PIN packages usually have the following 12 models: 0201,0402, 0603,0805, 1206,1210, 1812,1825, 2225,301 2, 3035.
