Description
EE19 Horizontal & Vertical High Frequency Ferrite Transformer
Product Overview
EE19 series horizontal and vertical high frequency transformers adopt low-loss manganese-zinc ferrite core, compact mini size design with competitive cost and stable long-term reliability.
This EE type ferrite transformer supports large output current, widely applied for power conversion circuit and EMI line filtering. We supply both horizontal and vertical pin layout versions to match different PCB layout demands. Two grades of polyurethane enameled wire (155℃ / 180℃ heat-resistant) are optional to adapt various high-temperature working environments. Compatible with multiple switching power supply circuits, inverters and small UPS equipment.
