B66414W EFD 15/8/5 coil formers from EPCOS are constructed from GRF thermosetting plastic and feature 8 squared pins. They meet the UL 94 V-0 standard and have an insulation class of IEC 60085:H with a maximum operating temperature of +180°C. These coil formers meet the IEC 60068-2-20 standard for solderability and resistance to soldering heat.
B66414B coil formers from EPCOS have 8-pins and feature J terminals. These coil formers are constructed from black GFR Liquid Crystal Polymer. They meet the UL 94 V-0 standard and have an insulation class of IEC 60085:F with a maximum operating temperature of +155°C. These coil formers meet the IEC 60068-2-58 standard for solderability and resistance to soldering heat.
Both varieties of coil former are suitable for use with EPCOS B66413 series transformer ferrite cores and the B66414 yoke.
