Shielded Power Inductors – VER2923 Document 834-1 Document 834-1 Revised 02/15/12 Core material Ferrite Terminations RoHS compliant tin-silver over copper. Other termina- tions available at additional cost. Weight 37 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 +85°C. Packaging: –40°C to +80°C Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C / 85% relative humidity) Failures in Time (FIT) / Mean Time Between Failures (MTBF) 38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332 Packaging 25 parts per tray PCB washing Only pure water or alcohol recommended Part Inductance1 DCR (mOhms)2 SRF typ3 Isat (A)4 Irms (A)5 number ±10% (µH) nom max (MHz) 10% drop 20% drop 30% drop 20°C rise 40°C rise VER2923-332KL 3.3 2.3 2.6 40 95.0 104 108 19 26 1. Inductance tested at 300 kHz, 0.1 Vrms on Agilent/HP 4192A. 2. DCR measured on a Keithley 580 micro-ohmmeter or equivalent. 3. SRF measured on an Agilent/HP 8753ES network analyzer. 4. DC current at which the inductance drops the specified amount from its value without cur- rent. 5. Current that causes the specified temperature rise of the winding from 25°C ambient. Temperature rise of the core is usually less than that of the winding. When Irms is greater than Isat, Isat is the more critical specification and Irms is shown in gray type. 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
- Designed for high current power supply applications with saturation current ratings to over 100 Amps
- Ideal for use in Class-D applications
- Flat wire windings provide extremely low DC and AC resistance
- Vertical mounting provides a small footprint Caution: This series is not intended for use in high vibration environments. We advise using additional means of securing the part to the circuit board to ensure its adhesion.
