Transformer & Inductor Tools

Our web-based proprietary tools help you find the parts to optimize your designs, streamlining your search for the best solution. This search is often complex. Our tools will help simplify the process.

Think of us as a design partner: If you've got questions, we're happy to work through them with you quickly and thoroughly.

DC-DC Optimizer

This complete converter application tool finds the most efficient inductor solutions and analyzes their performance to optimize your Buck, Boost and Buck-boost converters.

Power Inductor Finder and Analyzer

Identify the best power inductors for your specified parameters and review AC and DC losses, temperature rise, L vs. current, self-heating curves and more. Or if you already know your part number(s), skip the search and move directly to the performance analysis.

RF Inductor/Choke Finder and Analyzer

This powerful tool identifies the best RF inductors and chokes for your defined parameters. Search for L @ Frequency or Z @ Frequency for specific application conditions. Or skip the search function and proceed directly to performance analysis for known part number(s).

EMI Power Choke Impedance Finder

Identify the choke with the impedance chracteristic for your frequency range. Find a choke based on your defined parameters or directly compare performance of selected part numbers.

Common Mode Choke Finder and Analyzer

Find the best off-the-shelf common mode chokes for your required impedance, attenuation, or inductance. Or skip the search function and proceed directly to performance analysis for specific off-the-shelf part number(s)

Coupled Inductor Finder and Analyzer

Identify the best coupled inductors for your specified parameters. Display AC and DC losses, temperature rise, L vs current, self-heating curves and more. Or skip the search function and jump right into performance analysis for part number(s) you already know.

Current Transformer Finder

Match off-the-shelf current sense transformers to your application. See a list of suitable current transformers with a recommended terminating resistor.

Wirewound Ferrite Bead Finder and Analyzer

Display lists of off-the-shelf wirewound ferrite beads to meet your impedance@Frequency and current rating requirements. See performance curves including Impedance and inductance vs. Frequency.

DCR @ Temperature Tool

Coilcraft’s DCR @ Temperature Tool calculates the temperature-adjusted DCR for any standard Coilcraft inductor.  

Reference Design Inductor Finder

Your inductor choices should not be limited to those chosen by the IC companies. This tool finds all the latest and greatest inductors suitable for the published reference design you're using.
