1. When ordering, please specify **packaging** codes: 

| **PFL2510-472MEC** 

**Packaging: C** = 7″ machine-ready reel. EIA-481 embossed plastic tape (2000 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. Factory order only, not stocked (7500 parts per full reel). 

2. Inductance tested at 7.9 MHz, 0.1 Vrms using a Coilcraft SMD-A test fixture with an Agilent/HP 4286 impedance analyzer and Coilcraft-provided correlation pieces. 

3. DCR measured using a micro-ohmmeter. 

4. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. 

5. DC current that causes the specified inductance drop from its value without current. 

6. Current 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.
