Nanocrystalline Cores Common Mode Choke Core Product Description
A common mode choke core (CMC) is a type of inductor core that is used to suppress electromagnetic interference (EMI) in electronic circuits. It is designed to filter out noise that is common to both signal lines, such as those found in a twisted pair cable, while allowing differential signals to pass through unimpeded.
Nanocrystalline material with high and stable temperature characteristics is suitable for the radio noise and line noise filters of various inverter devices, switching mode power supplies and signal lines.
For EMI-noise suppression in switched mode power supplies, frequency inverters and many other applications, nano-crystalline 1K107 cores offer significant advantages in volume and magnetic properties.
The common mode choke core is an effective way to reduce electromagnetic interference in electronic circuits, and it is commonly used in applications such as power supplies, communication systems, and audio equipment.
Nanocrystalline Cores Emc Common Mode Choke Core Feature
- High inductance with a low number of turns and small winding capacities
- Broadband insertion loss curve with good damping performance over a wide frequency band
- Small choke size for volume and weight optimized solutions
- Excellent impedance character
- Low magnetostriction result in low noise components
Common Mode Choke Core Application
A common mode choke core is a type of inductor that is specifically designed to suppress common mode noise in electronic circuits. It consists of a ferromagnetic core with two windings wound around it in opposite directions, and is used to filter out unwanted signals that can cause interference in electronic equipment.
Here are some applications of common mode choke cores:
● EMC filters / Automotive parts
● Switch-mode power supplies / Solar inverters
● Frequency converter / Wind generators
● Home appliances / UPS / Welding equipments
