Leakage inductance is measured at primary terminals with all secondaries shorted. 3.Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the ���� part number (i.e. PA0648NL becomes PA0648NLT). Pulse complies to industry ���� ����� ���� standard tape and reel specification EIA481. ���� ����������� ����� ���� ��������� 4.The "NL" suffix indicates an RoHS-compliant part number. Non-NL suffixed parts are ��� ���� ����� !��"�# $%$� not necessarily RoHS compliant, but are electrically and mechanically equivalent to � � NL versions. If a part number does not have the "NL" suffix, but an RoHS compliant version is required, please contact Pulse for availability. �������������������� �� � � 5.The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range. ����� Inches Dimensions: Weight . . . . . . . . . . . . . .0.60 grams ����� mm Tape & Reel . . . . . . . . . . . .400/reel ��� Unless otherwise specified, Tube . . . . . . . . . . . . . . . . . .50/tube .010 all tolerances are ± 0,25 ��������� For More Information: ���������� Pulse Worldwide Pulse Pulse China Headquarters Pulse North China Pulse South Asia Pulse North Asia Headquarters Europe B402, Shenzhen Academy of Room 1503 150 Kampong Ampat No. 26 12220 World Trade Dr. Einsteinstrasse 1 Aerospace Technology Building XinYin Building #07-01/02 Kao Ching Rd.
