When ordering, please specify termination, and packaging codes: Core material Ferrite Terminations RoHS compliant tin-silver (96.5/3.5) over copper (leads), GA3416-CLD electroplated gold (<50 in) over nickel over phos bronze (additional Termination: L = RoHS compliant tin-silver (96.5/3.5) over copper mounting pads). Other terminations available at additional cost. (leads), gold over nickel over phos bronze (additional Weight 7.8 g mounting pads. Special order: T = RoHS tin-silver-copper (95.5/4/0.5) Ambient temperature 40C to +125C with Irms current or S = non-RoHS tin-lead (63/37). Maximum part temperature +165C (ambient + temp rise) Packaging: D = 13 machine-ready reel. EIA-481 embossed plastic tape (200 parts per full reel). Quantities less than Storage temperature Component: 40C to +165C full reel available: in tape (not machine ready) or Tape and reel packaging: 40C to +80C with leader and trailer ( 25 charge). Resistance to soldering heat Max three 40 second reflows at B = Less than full reel. In an effort to simplify our part +260C, parts cooled to room temperature between cycles numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30C / change the last letter of your part number from B to D. 85% relative humidity) 2. Maximum power into specified load that causes a 40C temperature Packaging 200/13 reel Plastic tape: 32 mm wide, 0.4 mm thick, rise. Measured at 1 kHz with a 14.4 Vdc supply for the 2-Ohm load 20 mm pocket spacing, 12.95 mm pocket depth and a 21 Vdc supply for the 4-Ohm load. Refer to Output Power table for typical output conditions. Tested using the TAS5414A Evaluation PCB washing Tested to MIL-STD-202 Method 215 plus an additional Board from Texas Instruments. aqueous wash. See Doc787 PCB Washing.pdf. 3. Inductance measured at 500 kHz, 0.5 Vrms, 0 Adc using an Agilent/ HP 4284A impedance analyzer. 4. DCR measured on a micro-ohmmeter. 5. SRF measured using Agilent/HP 8753D network analyzer. 6. Total harmonic distortion + noise measured at 23 W into a 2 -Ohm or 4-Ohm load at 1 kHz with a 21 Vdc supply. 7. DC current at 25C that causes the specified inductance drop from its value without current. 8. Current applied to both windings at the same time that causes the specified temperature rise from 25C ambient. This information is for reference only and does not represent absolute maximum ratings. 9. Electrical specifications at 25C. Refer to Doc 362 Soldering Surface Mount Components before soldering.
