## 1. Please specify **termination** and **packaging** codes:
**SER1052-572MLD**
- **Termination: L** = RoHS compliant tin-silver over copper (pins 1 and 2); matte tin over nickel over phos bronze (pin 3). Special order:
- **T** = RoHS tin-silver-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 (200 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 (700 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 4395A network analyzer and an Agilent/HP 16193A test fixture.
5. DC current at which the inductance drops the specified amount 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.
