Product Categories

• Parametric Search: A site-wide tool allowing users to sort, filter, and compare all Coilcraft products to find the ideal component.
• Power Inductors: Available in various structures, sizes, and inductance values for diverse power applications. Features the XGL Family known for low DC resistance and low AC losses in DC-DC converters.
• RF Inductors: Includes ceramic-core, ferrite-core, air core, conical inductors, broadband bias chokes, and RFID coils for radio frequency circuits.
• Transformers: Designed for applications like power conversion, capacitor charging, gate drive, Power over Ethernet (PoE), current sensing, ultrasonic sensing, and data-line isolation.
• EMI/POC/Chokes: Features EMI common mode chokes and wirewound ferrite beads designed to minimize electromagnetic interference and suppress noise effectively.

Design Tools & Analyzers

Coilcraft provides a suite of specialized online tools to simplify component selection and analysis:

• DC-DC Optimizer: Finds the most efficient inductor solutions for Buck, Boost, and Buck-Boost converters. Uses measured inductor data (not just theory) to visualize and compare efficiency, total loss vs. load current, IL waveforms, L vs. I, and temperature rise (ΔT) across different inductors for optimal design. Analyzes all inductance values.
• Power Inductor Finder and Analyzer: Identifies suitable power inductors based on Lnom (nominal inductance) or L @ I (inductance at specific current). Allows analysis and comparison of AC/DC losses, temperature rise, L vs. current, and self-heating curves. Users can also directly analyze known part numbers.
• RF Inductor/Choke Finder and Analyzer: Searches for RF inductors and chokes based on L @ Frequency or Z @ Frequency. Enables quick analysis and comparison, displaying performance curves like L, Q, Z, and ESR versus frequency. Direct analysis of known part numbers is available.
• Common Mode Choke Finder and Analyzer: Finds off-the-shelf common mode chokes based on required impedance, attenuation, or inductance. Allows comparison and displays common/differential mode impedance and attenuation vs. frequency curves. Supports direct part number analysis.
• Coupled Inductor Finder and Analyzer: Identifies multi-winding inductors suitable as transformers or coupled inductors (e.g., for SEPIC, ZETA). Analyzes total AC/DC losses, temperature rise, L vs. current, and self-heating. Supports direct part number analysis.
