IHLM-2525CZ-01

Vishay Dale

Molded, Low Profile, High Current Inductors

FEATURES

• Lowest molded height (3.0 mm) in this package

footprint

• Shielded construction

• Frequency range up to 5.0 MHz

• Lowest DCR/µH, in this package size

• Handles high transient current spikes without saturation

• Ultra low buzz noise, due to composite construction

• Encapsulated body offers improved environmental

protection and moisture resistance

Manufactured under one or more of the following:

US Patents; 6,198,375/6,204,744/6,449,829/6,460,244.

Several foreign patents, and other patents pending.

• Higher dielectric withstanding voltage vs. IHLP

• Flame retardant encapsulant (UL 94 V-0)

• Corrosion resistant package

All test data is referenced to 25 °C ambient

Operating temperature range - 55 °C to + 125 °C

DC current (A) that will cause an approximate ΔT of 40 °C

DC current (A) that will cause L₀to drop approximately 20 %

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.
