Inductance is measured where applicable, with north primary windings connected in series (2 to 5, with 3 and 4 shorted). Notes: 2. Leakage inductance is measured on windings (2-5) with (3-4) and (7, 8, 9, 10, 11) shorted. 3. Optional Tape & Reel packaging can be ordered by adding a suffix at the end of the part number (i.e. R8301NLT) www.inrcore.com 1 N014.
