FERRINOX toroids provide high inductance values minimum volume. magnetic circuit with airgap offers minimum leakage inductance optimal coupling. uniform cross section area along magnetic path allows operation maximum flux density therefore preventing local saturation supplementary losses.
APPLICATIONS
toroids used wide range applications including noise transformers, converter transformer, pulse transformers, delay lines, ground fault interruptor. suppression, chokes, wide band
Material selection noise suppression facilitated addition cut-off frequency data permeability versus frequency curves.
