1. When ordering, please specify

packaging code:

1812DPS-473MLC

Packaging: C = 7

″ machine-ready reel. EIA-481 embossed plastic

tape (600 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 C instead.

D = 13

″ machine-ready reel. EIA-481 embossed plastic

tape (2200 parts per full reel).

2. Per winding. Tested at 100 kHz, 0.1 Vrms, 0 Adc.

3. Q measured at 1 MHz.

4. DC current at which the inductance drops 10% (typ) from its value

without current.

5. Current that causes a 40°C temperature rise from 25°C ambient.

6. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
