Wurth Elektronik WE-CMB Series Common Mode Choke, 4mH Inductance, 1.5A Maximum DC Current - 744821240

This common mode choke is a through-hole EMI suppression component designed to reduce differential noise in AC and DC applications. It operates across a wide temperature range and is suitable for installations requiring solder-pad termination and four-pin connection. The component meets several industry approvals and is intended for use where moderate current handling and noise attenuation are required.

Features and Benefits:

• ±30% inductance tolerance provides predictable filtering performance
• 4mH inductance improves high-frequency common-mode attenuation
• 1.5A maximum DC current supports moderate-power circuits
• 250V AC choke voltage enables use on mains-level lines
• Maximum operating temperature 125°C allows elevated-temperature operation

Applications

• Suitable for EMI suppression on power input lines
• Ideal for mains-interfaced filtering modules
• Used with control electronics requiring noise reduction
• Suitable for retrofit suppression in industrial equipment
• Can be used for filtering in consumer appliances

What pin configuration does it use?

It uses a four-pin layout with solder-pad termination for through-hole mounting.

What is the measured DC resistance limit?

The maximum DC resistance is specified as 240Ω.

Which environmental approvals does it carry?

It holds VDE, ENEC, RoHS and REACH compliance approvals.

What frequency was used for inductance testing?

Inductance was characterised at a test frequency of 10kHz.

What are the allowable operating temperatures?

The component is rated for use from -40°C up to 125°C.
