3. Countermeasure against spike ripples
4. EMI/RFI filters
5. DC/DC converters
6. IP and OP devices

Product Features：

1、Common mode inductors are designed to suppress electromagnetic interference. They are used primarily to filter out 'common mode' noise in electrical circuits.

2、Power choke coils usually have a coil of wire wound around the core of a magnet.

3、Common Mode Inductors are used extensively in power supplies, data lines, and communication systems to improve the signal integrity.

4、High enough impedance to the common mode signals and low to the differential signals (Differential mode signals pass on with nearly no attenuation).

5、Available as surface mount or through-hole options depending on application needs.

6、Performing, capable of removing AC frequency noise, preventing AC frequency interference, protecting voltage spikes, and suppressing voltage fluctuations, improving redundancy.

7、Common mode inductors generally developed to comply with industry specifications regarding safety and performance, making them versatile enough to pair with a range of electronic devices.
