注释

When ordering, please specify packaging code: e.g. LPHR8045-223MEC
Inductance is for the primary, measured with the windings connected in parallel at 100 kHz, 0.1 Vrms, 0 Adc.
DCR is measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
Isolation (hipot) is measured from primary to secondary for one minute.
Leakage inductance is for the primary winding, measured with the secondary winding shorted.

包装:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (250 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (1000 parts per full reel).
