1. When ordering, please specify packaging code:
UA8013-ALD
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Quantities less than full reel available: in tape (not machine ready) or with
leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes.
When ordering, simply change the last letter of your part number from B to D.
2. Inductance measured at 100 kHz, 1.0 Vrms, 0 Adc using an Agilent/HP 4284A impedance analyzer.
3. DCR is for each winding, measured on a micro-ohmmeter.
4. SRF measured using Agilent/HP 8753D network analyzer.
5. DC current (typical) at which the inductance drops the specified amount from its value without current.
6. Current applied to windings at the same time that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
