IHLP® Commercial Inductors, High Saturation Series
DESIGN SUPPORT TOOLS click logo to get started
Notes
• All test data is referenced to 25 °C ambient
• Operating temperature range -55 °C to +125 °C
• The part temperature (ambient + temp. rise) should not exceed
125 °C under worst case operating conditions. Circuit design,
component placement, PWB trace size and thickness, airflow
and other cooling provisions all affect the part temperature. Part
temperature should be verified in the end application.
• Rated operating voltage (across inductor) = 75 V
(1) DC current (A) that will cause an approximate ΔT of 40 °C
(2) DC current (A) that will cause L0 to drop approximately 20 %
FEATURES
• Lowest height (1.8 mm) in this package footprint
• Shielded construction
• Excellent DC/DC energy storage up to 5 MHz.
Filter inductor applications up to SRF (see
Standard Electrical Specifications table)
• Lowest DCR/μH, in this package size
• Handles high transient current spikes without
saturation
• Ultra low buzz noise, due to composite construction
• IHLP design. PATENT(S): www.vishay.com/patents
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
• PDA / notebook / desktop / server applications
• High current POL converters
• Low profile, high current power supplies
• Battery powered devices
• DC/DC converters in distributed power systems
• DC/DC converter for Field Programmable Gate Array
(FPGA)
