Actual use (0.548 μH hollow coil, high frequency low inductance)
1. RF category: Bluetooth module, WiFi antenna matching inductor, RF filter, high-frequency choke coil;
2. Switching power supply high-frequency loop: fast charging power supply, high-frequency Buck-Boost circuit, resonant circuit (resonant circuit within tens of MHz);
3. EMI filtering: USB-PD fast charging, high-frequency interference suppression at the adapter input, filtering out dozens of MHz high-frequency noise;
4. Wireless charging auxiliary coil, RF transmission circuit, LC oscillation circuit;
5. High-frequency power amplifier, RF signal coupling, not suitable for low-frequency 50Hz industrial frequency circuit (low frequency needs a large inductance, hollow coil can not do it).

The product parameters of this series can be customized according to customer requirements, welcome to consult and customize according to drawings and samples.
