IHLP® Commercial Inductors, High Saturation Series
FEATURES
• Alternative IHLP parts with short 10 week lead
time
• Shielded construction
• Excellent DC/DC energy storage up to 1 MHz to
2 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
• 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)
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
(1) DC current (A) that will cause an approximate T of 40 °C
(2) DC current (A) that will cause L0 to drop approximately 20 %
(3) DC current (A) that will cause L0 to drop approximately 30 %
