1. When ordering, please specify packaging code:
CU8838-ALD
Packaging: D = 13″ machine-ready reel. EIA‑481 embossed plastic
tape (500 parts per full reel). Quantities less than fullreel 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 to D.
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft
SMD­‑A fixture in an Agilent/HP 4284A LCR meter.
3. SRF measured using an Agilent/HP4291A impedance analyzer and aCoilcraft 16193 fixture.
4. DC current at 25°C that causes the specified inductance drop from its
value without current. Click for temperature derating information.
5. Current that causes the specified temperature rise from 25°C ambient.
This information is for reference only and does not represent absolutemaximum ratings. Click for temperature derating information.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
