Description
EE19 Horizontal & Vertical High Frequency Ferrite Transformer
Product Overview
Furthermore, our EE19 Transformer includes both horizontal and vertical versions of high-frequency ferrite transformers. This series adopts low-loss manganese-zinc ferrite core, featuring ultra-compact mini size, competitive cost and stable long-term operation reliability.
In addition, this classic EE type ferrite transformer supports large output current, which fits power conversion circuits and EMI line filtering applications perfectly. We manufacture two pin layout options (horizontal & vertical) to match diverse PCB layout design demands.
Two temperature grades of polyurethane enameled wire are optional: 155℃ and 180℃ heat-resistant types, which can adapt various high-temperature working environments. The EE19 Transformer is fully compatible with mainstream flyback switching power supply circuits, small inverters and miniature UPS equipment.
