メモ

When ordering, please specify packaging code: e.g.UA7902-ALD
Inductance is for the primary, measured on an Agilent/HP 4284 at 250 kHz, 0.1 Vrms, 0 Adc.
DC current that causes an inductance drop of 30% (typ) from its value without current.
DCR for secondary is for the windings connected in parallel.
Leakage inductance measured between pins 1 and 3 at 250 kHz, 0.1Vrms, 0 Adc with all secondary pins shorted.
Isolation (hipot) measured between windings for one minute.

終端処理:

RoHS-compliant. 260°C compatible. RoHS tin-silver-copper (95.5/3.8/0.7) over tin over nickel over phos bronze.

パッケージ:

D = 13″ machine ready reel. EIA-481 embossed plastic tape. 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 D.
