PRODUCT DATA SHEET P7600 Family HIGH POWER INDUCTOR Features Applications ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ High Current Low Loss, Low DCR Closed magnetic circuit Low Profile Lead-free (Pb-free) RoHS compliant Alloy powder core Helical rectangular wire DC-DC Converters Voltage Regulator Modules Distributed Power Servers Workstations Telecom equipment Notebook and handheld equipment DESCRIPTION The P7600 family comprises high-energy-density surface mount inductors. The family employs helical windings of rectangular wire, giving excellent DC resistance, thermal efficiency and high frequency performance. A distributed gap powder core is used, yielding stable inductances at very high currents with a closed magnetic current. ETALDOC 826/4 Page 1 of 3 Components are supplied with Pb-free terminations in tape and reel packaging, and are compliant with RoHS Directive 2002/95/EC, and suitable for lead-free and conventional placement and reflow.

Inductance measured at 100kHz, 100mV. 2. Rated current is the current at which the temperature rise is 45ºC. 3. Saturation current, Isat, is the DC current at which the zero-current inductance falls by 10%. For this family, inductance falls by around 25% for a current of 2x Isat. 4. Operating temperature -25ºC to +105ºC. 5. For non-standard inductance values, please contact Profec.
