1. When ordering, please specify **termination** and **packaging** code: 

## | **SER8052-103MED** 

**Termination: E =** RoHS tin-silver over tin over nickel over phos bronze (pins 1 and 2); Matte tin over nickel over phos bronze (pin 3). **Special order: T** = RoHS tin-silver-copper over copper (95.5/4/0.5) or **S** = non-RoHS tin-lead (63/37). 

**Packaging: C** = 7″ machine-ready reel. EIA-481 embossed plastic tape (250 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(1000 parts per full reel). 

2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A or equivalent. 

3. DCR measured on a micro-ohmmeter. 

4. SRF measured using an Agilent/HP 8753D network analyzer and an Agilent/HP 16193A test fixture. 

5. DC current at 25°C that causes the specified inductance drop 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.
