DESCRIPTION

The P7640 family comprises of very high

current shielded power choke coil in low profile size.

The P7640 family is compliant with RoHS Directive

2002/95/EC and suitable for lead-free and convention

placement and reflow.

The products self-leaded construction consist of ferrite

core and helical coil from enamel-coated copper wire.

The range covers inductance values from 0.085µH to 0.22µH,

and provides compact solutions for high power

applications with saturation currents ranging between

33 A to 70 A.

Notes:

a) Operating Temp. : -40°C to +125°C

b) Heat Rated Current (Irms, A) will cause the coil temperature rise approximately ∆t of 40°C without core loss

c) Saturation Current (Isat, A) will cause L0 to drop 20% typical

d) Part Temperature (Ambient+Temp.Rise): Should not exceed 125°C under worst case operating conditions.

CHARACTERISTIC CURVES

a) The inductance vs. current and temperature characteristic curves presented are typical values

b) The inductance vs. current curves are generated by measuring inductors at 25ºC ambient temperature.

c) Temperature rise is measured at an ambient temperature of 25ºC. A current is applied for 8 minutes and temperature is measured

when the point of the components temperature is stable using an infrared thermometer directed at the bottom surface of the

component. No forced air cooling is applied.

d) Temperature response need to be verified in specific applications and can only be carried out by the customer
