ELF-18D450A

Common Mode Chokes Overview

The ELF-18D450A is a two-line common mode choke manufactured by Panasonic Electronic Components. It utilizes a powdered iron core and supports through-hole mounting. The component operates within a temperature range of -20°C to 105°C. It features a typical DC resistance (DCR) of 110mOhm and is rated for a current capacity of 2A.

Common Mode Chokes Feature Summary

• Utilizes a powdered iron core for low loss performance up to 3MHz
• Features monolithic construction with closed magnetic circuit design
• Provides effective common mode noise suppression for line filters

Common Mode Chokes Applications

• Notebook PC power supplies
• Desktop PC DC-DC converters
• Server high-current power supplies

Common Mode Chokes Procurement Notes

Verify the specific suffix against official Panasonic documentation, as variations such as ELF-18D450G or ELF-18D450C exist within the same series. Confirm that the required current rating and inductance specifications align with the target application before procurement. Ensure compatibility with through-hole assembly processes.

Common Mode Chokes Selection Notes

Select this component for applications requiring robust common mode filtering in compact power systems. The powdered iron core offers advantages in high-frequency noise attenuation. Consider the 2A current rating and thermal limits when designing for continuous operation in enclosed environments.

Common Mode Chokes Part Context

This part belongs to the ELF series of line filters designed for electronic equipment. It is distinct from other Panasonic components like the ECWF film capacitors or EEUFC aluminum electrolytic capacitors found in general catalogs. The series focuses on electromagnetic interference suppression for consumer electronics.
