Inductance is one of the most important components in high-frequency analog circuits and signal processing for mobile phones, RFID, testing equipment, GPS, radar, Wi-Fi, satellite radio, and other applications. Generally, it can undertake several main functions including circuit tuning, impedance matching, high-pass and low-pass filters, and can also be used as RF throttling.
There are multiple options for an electronic engineer who chooses to use RF Induc
Magnetic Beads have high resistivity and magnetic permeability, which is equivalent to a series of resistance and inductance, but the resistance value and Inductance Value Change with frequency. It has better high-frequency filtering characteristics than ordinary inductor, and presents resistance at high frequencies, so it can maintain a high impedance within a very wide frequency range, thus improving the FM filtering effect.
Inductance can be used
DC_DC inductor Selection Guide
One: Inductance main parameter meaning
The following parameters should be considered in the selection of inductor for DC-DC peripheral: Inductance L, self-resonant frequency F0, internal resistance DCR, saturation current ISAT, effective current irms.
The larger the inductance l:l, the stronger the energy storage capacity, the smaller the ripple, the smaller the required filte
There are some applications for magnetic beads and inductors. Now let's make a brief summary of them.
In our circuit design, magnetic beads are mainly used to suppress high-frequency conducting interference signals, while inductance is mainly used to suppress low-frequency interference signals. When EMI suppression is performed on interference signals with a wide frequency band, multiple inductance or magnetic beads of different properties must be used at the same time.

You can see the "+" and "-" On the capacitor. This is the withstand range of the capacitor voltage. The smaller the value, the better the capacitance. In addition, the welding of capacitors should be clean and the cables should not be distorted. If the metal aluminum shell slice capacitor and yellow square ta capacitor is more, the gener
