See Doc787_PCB_Washing.pdf. ## 1. When ordering, specify **tolerance** , **termination** and **packaging** codes: , ~~_~~ | ~~_»~~ ~~**_** ___1~~ **DO3316T-474MLD** **Tolerance: M =** 20%, **K** = 10% (Table shows stock tolerances in bold.) **Termination: L** = RoHS compliant tin-silver-copper over copper. Special order: **S** = non-RoHS tin-lead (63/37). **Packaging: D** = 13″ machine-ready reel. EIA-481 embossed plastic tape (750 parts per full reel). 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, 0 Adc. 3. Tolerances in bold are stocked for immediate shipment. 4. SRF measured using Agilent/HP 8753D network analyzer. 5. DC current at 25°C that causes an inductance drop of 10% (typ) from its value without current. Click for temperature derating information. 6. Current that causes a 40°C 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.
