Wurth Elektronik WE-CMB Series Common Mode Choke, 1mH Inductance, 3A Current - 744822301
This common mode choke is an EMI filter component designed to suppress differential and common-mode noise in AC and DC circuits. It is a radial-mounted, four-pin device intended for through-hole soldering and operation across a broad temperature range. Constructed with a manganese‑zinc core, it is suitable for applications requiring moderate inductance and continuous currents up to the rating shown.
Features and Benefits:
• Low resistance minimises insertion loss for higher efficiency
• Rated for 3A continuous current to handle moderate loads
• ±30% inductance tolerance permits predictable filtering at 50Hz
• Withstands up to 125°C for demanding thermal environments
• Solder termination supports robust mechanical and electrical connections
• Rated for 3A continuous current to handle moderate loads
• ±30% inductance tolerance permits predictable filtering at 50Hz
• Withstands up to 125°C for demanding thermal environments
• Solder termination supports robust mechanical and electrical connections
Applications
• Suitable for mains EMI suppression in power supplies
• Used with AC lines up to 250V AC for noise reduction
• Ideal for filtering in industrial control equipment
• Can be used for general-purpose suppression in consumer electronics
• Appropriate for designs requiring radial mounting and 4‑pin connections
• Used with AC lines up to 250V AC for noise reduction
• Ideal for filtering in industrial control equipment
• Can be used for general-purpose suppression in consumer electronics
• Appropriate for designs requiring radial mounting and 4‑pin connections
What lead spacing does it require for PCB layout?
The component uses a 7.7mm lead pitch suited to radial through‑hole layouts.
How does core material affect performance and frequency behaviour?
The manganese‑zinc core provides high permeability suitable for low‑frequency suppression around the specified test frequency.
What are the Terminal and mechanical Interface details?
The part uses solderable leads of 0.7mm diameter and a radial mounting style for secure board attachment.
What are the environmental operating limits for continuous use?
It is specified to operate between -40°C and 125°C for a wide range of ambient conditions.
