When ordering, please specify **termination** and **packaging** codes: | ~~——_~~ **DO5010H-105MLD** - **Termination: L** = RoHS compliant tin-silver over copper. **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. Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge). - **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. 2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4284A LCR meter or equivalent. 3. SRF measured using Agilent/HP 8753D network analyzer. 4. DC current at which the inductance drops 10% (typ) from its value without current. 5. Current that causes a 40°C temperature rise from 25°C ambient. 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering. **US** +1-847-639-6400 sales@coilcraft.com **UK** +44-1236-730595 sales@coilcraft-europe.com **Taiwan** +886-2-2264 3646 sales@coilcraft.com.tw **China** +86-21-6218 8074 sales@coilcraft.com.cn **Singapore** + 65-6484 8412 sales@coilcraft.com.sg Document 284-1 Revised 12/29/21 © Coilcraft Inc. 2021 This product may not be used in medical or high risk applications without prior Coilcraft approval.
