Wurth Elektronik WE-CMB Series Common Mode Choke, 5mH Inductance, 250V AC Choke Voltage - 744823305
This common mode choke is designed to attenuate differential noise in through-hole installations and support AC mains applications. It is rated for operation across a wide temperature span and carries multiple safety approvals, making it suitable for regulatory-conscious designs that require a solder-pad 4-pin through-hole EMI filter component.
Features and Benefits:
• ±30% inductance tolerance enables predictable suppression performance
• 95mΩ low DCR reduces insertion loss during normal operation
• 2.5A maximum DC current supports moderate power lines
• Tested at 10kHz to verify impedance characteristics
• 125°C maximum operating temperature permits high-temperature deployment
• 95mΩ low DCR reduces insertion loss during normal operation
• 2.5A maximum DC current supports moderate power lines
