IF International Flathead™ Transformers

Signal Transformer / Bel IF International Flathead™ Transformers implement unique insulating techniques to meet international safety requirements. These transformers feature 115V/230V dual primaries, 4000Vrms Hipot dielectric strength, dual secondaries in series or parallel, and Class B insulation system. Bel Signal Transformer IF transformers are UL-recognized to UL506 / UL5085-2, UL1446 (E66312) certified, CSA certified to C22.2 #66.1, and VDE certified to VDE 0805 / EN 60950. These transformers are ideal for low-power applications requiring reduced magnetic radiation and minimum height.
