necessary for AC currents. PCB layout, trace thickness and width, air-flow, and

proximity of other heat generating components will affect the temperature rise. It

is recommended that the temperature of the part not exceed 125°C under worst

case operating conditions verified in the end application.

Packaging

• Supplied in tape and reel packaging, 2600 per reel

B p-p = K*L*∆I, B p-p(mT), K: (K factor from table), L: (Inductance in uH),

∆I (Peak to peak ripple current in Amps).

SD53 = Product code and size; -xxx = Inductance value in uH;

R = decimal point; If no R is present, third character = # of zeros.

-R suffix = RoHS compliant
