1. Specify **tolerance** , **termination** and **packaging** codes: {_______ | ~~,______|~~ **DO5022P-105MLD Tolerance: M =** 20%, **K** = 10% (Table shows stock tolerances in bold.) 

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

**Packaging: D** = 13″ 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 D instead. 

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

3. Tolerances in bold are stocked for immediate shipment. 

4. SRF >13 MHz measured using Agilent/HP 8753D network analyzer; <13 MHz using Agilent/HP 4192A. 

5. DC current at which inductance drops the specified amount from its value without current. 

6. Current that causes a 40°C temperature rise from 25°C ambient. 

7. Electrical specifications at 25°C. 

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