Toroidal Cores

Product catalog summary
Overview: This document provides technical specifications and details for TDK's toroidal cores used in switching power supplies. These cores are designed for applications such as transformers, inductors, choke coils, filters, and current sensors.
Specifications:
  • Ferrite materials available with initial permeability (µi) ranging from 5500 to 10000.
  • Insulation coatings available in epoxy and paraxylylene.
  • Dielectric breakdown voltage is a minimum of 1000Vd.c.
Applications: The toroidal cores are suitable for choke coils, filters, current sensors, EMI/RFI filters, and balun transformers.
Core Dimensions and Materials:
  • Various sizes from T14 to T44.5 with materials HS52, HS72, and HS10.
  • Dimensions are specified with tolerances, and effective parameters such as Ae (effective cross-sectional area) and AL-value (inductance factor) are provided.
Ordering Information: Cores can be ordered with specific dimensions and material codes. Epoxy-coated products require an 'E' suffix in the part number.
Key Data from Tables:
  • Dimensions and effective parameters for each core size are listed, including outer diameter (øA), inner diameter (øB), and thickness (C).
  • AL-values are provided for different materials, indicating the inductance factor at specified frequencies and voltages.
  • Weight and volume (Ve) of each core are also specified.

Toroidal Cores-1

TDKs toroidal cores are available in a number of sizes. Therefore, by selecting the ferrite material which corresponds to the application, it is possible to design stable transformers, inductors, etc. to cover a wide band range. FEATURES ҕSelection of core material to correspond to the application is possible as a result of standard ferrite materials with i=5500 to 10000. ՕEpoxy and paraxylylene insulation coating is available. APPLICATIONS Choke coils, filters, current sensors, EMI/RFI filters, balun trans-formers.
