Coilcraft New EMI Power Choke Impedance Finder Tool
- Find off-the-shelf, high-current, high-impedance inductors forvarious types of EMI filters, such as LC low-pass filters, “Pi” filters, “T” filters, and others
- Quickly analyze and compare one or more part numbers of your choice
- Review performance curves at your desired frequency, including L vs. F and Z vs. F
Coilcraft’s EMI Power Choke Impedance Finder is a powerful search and analysis tool for finding the optimal off-the-shelf inductors/chokes for different types of EMI filters (e.g., LC low-pass filters, “Pi” filters, “T” filters, etc.) to greatly suppress unwanted EMI noise. It helps to optimize the design of an input EMI filter or a second stage output filter for switching power supplies, as well as many other applications requiring noise reduction.
The Z @ Frequency search option allows you to find inductors that perform at your desired frequency in one simple step. The search results identify inductors suitable for the impedance requirement at a single frequency or a range of frequencies, while also displaying a full range of performance information, including Impedance vs. Frequency and Inductance vs. Frequency.
If you have already has identified suitable Coilcraft part numbers, you can skip the search function and proceed directly to the Analyze & Compare tab for performance analysis.
