D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (175 parts per full reel). Quantities less than full
reel available: in tape (not machine ready) or withleader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our partnumbering system, Coilcraft is eliminating the needfor multiple packaging codes. When ordering, simply
change the last letter of your part number from B toD.
2. Inductance is for the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc.
3. DCR for the secondary is with both windings connected in parallel.
4. Leakage inductance measured between pins 1 and 3 with all other pins
shorted.
5. Turns ratio is with the secondary windings connected in parallel.
6. Peak primary current drawn at minimum input voltage.
7. Output is with the secondary windings connected in parallel.
8. Auxiliary winding 6.8 V, 0.02 A.
9. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
