Inductance measured at 500 kHz, 0.1 Vrms,

0 Adc on an Agilent/HP 4284A LCR meter or

equivalent. 2. DCR measured on a Keithley 580 micro- ohmmeter or equivalent. 3. SRF measured using an Agilent/HP 4395A network analyzer and an Agilent/HP 16092A test fixture. 4. DC current at which the inductance drops the specified amount from its value without current. 5. Current that causes a the specified tempera- ture rise from 25°C ambient. 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Com- ponents” before soldering.

  • Perfect for high current, low voltage power supply applications
  • Extremely low DCR; Current handling to >100 Amps
  • Higher inductance values than other SER series – up to 33 µH Core material Ferrite Core and winding loss See www.coilcraft.com/coreloss Terminations RoHS compliant tin-silver over copper. Other terminations available at additional cost. Weight SER2814L – 27.5 g; SER2814H – 28.7 g; SER2817H – 34.7 g Ambient temperature –40°C to +85°C with Irms current, +85°C to +125°C with derated current Storage temperature Component: –40°C to +125°C. Tray packaging: –40°C to +80°C Resistance to soldering heat Max three 40 second reflows at +260°C, parts cooled to room temperature between cycles Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C / 85% relative humidity) Mean Time Between Failures (MTBF) 26,315,789 hours Packaging 25 pieces per tray PCB washing Only pure water or alcohol recommended Caution: This series is not intended for use in high vibration or mechanical shock environments. We advise using additional means of secur - ing the part to the circuit board to ensure its adhesion. Consider our SER2900 series, which offers nearly identical electrical charac- teristics and incorporates a third mount pad for better stability and board adhesion.
