Hipot: 4000VAC between primary to secondary and windings to core. 3 8. Recommended Fuse : Series: Littelfuse p/n 313 1.5HXP, 1.5A 250V, slow blow, ¼ x 1 ¼ or, Cooper Bussmann p/n BKMDL-1½ , 1.5A 250V, ¼ x 1 ¼ Parallel: Littelfuse p/n 313 3HXP, 3A 250V, slow blow, ¼ x 1 ¼ or, Cooper Bussmann p/n BKMDL-3, 3A 250V, ¼ x 1 ¼ Construction: Dual bobbin construction with an insulated shroud, both made of a high temperature material that exceeds UL flammability requirements. Safety: Since the dual bobbin construction effectively reduces capacitance, electrostatic shielding is not required.
