R Type Silicon Transformer Core

The feature of toroidal core

·Smaller size

·Lighter weight

·Less magnetic leakage

·Better over-load capacity

·Low temperature rise

·Easier design and mount

Toroidal core application:

·Power transformer

·Inductor

·Instrument transformer

·Audio transformer

·Voltage regulators

·Ballast

Two series of toroidal core

·A series

A round core wound by automatic machines with one continuous tape of CRGO silicon steel and annealed in a tunnel furnace under the protection of inert gases.

Material thickness: 0.30mm,  0.27mm,  0.23mm, 0.10mm,  0.08mm and 0.05mm

·B series

B series core commonly used as a replacement of EI and other toroidal transformers with lower magnetic loss requirement.

Material thickness: 0.30mm, 0.27mm, 0.23mm
