2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4263B LCR meter or equivalent. 

## 1. When ordering, please specify **termination** and **packaging** codes: | ~~———_~~ **SER1410-202MED** 

   3. DCR measured on a Keithley 580 micro-ohmmeter or equivalent. 

- **Termination: E** = RoHS compliant tin-silver-over copper. Special order: **T** = RoHS tin-silver-copper over copper (95.5/4/0.5) or **S** = non-RoHS tin-lead (63/37). 

   4. SRF measured using an Agilent/HP 4395A network analyzer and an Agilent/HP 16193A test fixture. 

   5. Typical dc current at 25°C that causes the specified inductance drop from its value without current. Click for temperature derating information. 

- **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). 

   6. Typical 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. 

- **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. 

7. Electrical specifications at 25°C. 

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