RL-8250
HIGH CURRENT SMD
POWER INDUCTORS*
FEATURES
• Lowest height in this package footprint.
• Shielded construction.
• Lowest DCR/µH, in this package size.
• Handles high transient current spikes without saturation.
• Ultra low buzz noise, due to composite construction.
• Frequency up to 5MHz.
• Lead Free (Pb).
APPLICATIONS
Excellent for use in PDAs, notebook computers, desktop com-
puters, server applications, high current POL converters, low
profile high current power supplies, battery powered devices,
DC/DC converters in distributed power systems and Field
Programmable Gate Arrays.
GENERAL SPECIFICATIONS
• Operating Temperature: -55°C - +125°C.
• All test data is referenced to 25°C ambient.
• Heat Rated Current (Irms) will cause the coil temperature to
rise approximately 40°C above 25°C ambient without core loss.
• Saturation Current (Isat) will cause L0to drop approximately
20%.
• The part temperature (ambient + temp. rise) should not exceed
125°C under worst case operating conditions.
*Patented in China and Taiwan
