Wurth Elektronik WE-CMBNC Series Common Mode Choke, 10mH Inductance, 2A Maximum DC Current - 7448022010

This common mode choke is a through‑hole EMI suppression component designed for mains and signal‑line interference reduction in electronic assemblies. It uses a nanocrystalline core to provide magnetic coupling for differential noise attenuation while operating across a wide temperature range. The device is supplied in tray packaging with solder pad terminations and holds approvals that support use in regulated environments.

Features and Benefits:

• 10mH inductance reducing common‑mode noise levels
• 2A maximum DC current enabling moderate current handling
• 85mΩ maximum DCR minimising voltage drop and losses
• 250V AC choke voltage allowing line‑level applications
• -40°C to 125°C temperature range for elevated thermal endurance

Applications

• Suitable for EMI suppression on power input lines
• Ideal for industrial control interfaces requiring noise filtering
• Used with mains‑connected converters and power supplies
• Can be used for signal‑line interference mitigation in equipment
• Suitable for assemblies needing tray‑packaged components

What core material is used and how does it affect performance?

The component employs a nanocrystalline core which provides high permeability for effective common‑mode attenuation at the specified test frequency.

What test conditions define the stated inductance?

Inductance is measured at a test frequency of 10kHz, with a tolerance range of -30 to +50% around the nominal value.

How is the component mounted and terminated on the board?

It is a through‑hole device with four pins and solder pad termination intended for wave or manual soldering processes.

What approvals support use in regulated environments?

It holds ENEC, RoHS, REACH and VDE approvals indicating conformity with applicable safety and material restrictions.

How are size and packaging conveyed for handling and storage?

Physical envelope dimensions are 18mm length, 14mm depth and 22mm height, and units are supplied in tray and carton packaging.
