**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. Factory order only, not stocked (4000 parts per full reel). 

2. Inductance tested at 1 MHz, 0.1 Vrms, 0 Adc. 

3. DCR measured on a micro-ohmmeter. 

4. SRF measured using Agilent/HP 4395A or equivalent. 

5. DC current at which the inductance drops 30% (typ) from its value without current. Click for temperature derating information. 

6. Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Click for temperature derating information. 

7. Electrical specifications at 25°C. 

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