1. When ordering, please specify packaging code:
LPR6235-253PML
C
Packaging: C =7
″ machine-ready reel. EIA-481 embossed plastic
tape (350 parts per full reel).
B = Less than full reel. In tape, but not machine ready. To
have a leader and trailer added ($25 charge), use
code letter D instead.
D =13
″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (1500 parts per
full reel).
2. Inductance is measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP
4284A LCR meter or equivalent.
3. SRF measured using an Agilent/HP 4191A or equivalent.
4. DC current applied to L1, at which the inductance drops 10% from its
value without current.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
These shielded parts are only 3.5 mm high and 6 mm
square. The excellent coupling coefficient (k = 0.95)
makes them ideal for use in a variety of applications,
such as flyback converters and step-up pulse trans-
former applications.
The high
Isat and low DCR ratings of these low profile
parts provide high efficiency and excellent current han-
dling in a rugged, low cost design.
Custom inductance values and turn ratios may be avail-
able upon request.
