1. When ordering, please specify

tolerance and packaging codes:

1812FS-105JLC

Tolerance:

J = 5% K = 10%

(Table shows stock tolerances in bold.)

Packaging:

C = 7

″ machine-ready reel. EIA-481 embossed plastic

tape (600 parts per full reel).

B = Less than full reel. On tape, but not machine ready.

To have a leader and a 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. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft

SMD-A fixture in an Agilent/HP 4263B impedance analyzer.

3. Tolerances in bold are stocked for immediate shipment.

4. Q measured at 1 MHz on an Agilent/HP 4291A with an Agilent/

HP 16193 test fixture.

5. DCR measured on a micro-ohmmeter and a Coilcraft CCF840 test

fixture.

6. SRF measured using an Agilent/HP 8753D network analyzer and a

Coilcraft SMD-D test fixture.

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

without current.

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

9. Electrical specifications at 25°C.

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