Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.10V , 0.0Adc

K-factor: Used to determine B for core loss (see graph). B = K

K: (K-factor from table), L: (inductance in μH), ΔI (peak-to-peak ripple current in amps).

Part Number Definition: SDH2812-xxx-R

ΔI. B (Gauss),

rms

p-p

: DC current for an approximate temperature rise of 40°C without core loss. Derating is

rms

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

other heat generating components will affect the temperature rise. It is recommended the part

temperature not exceed 125°C under worst case operating conditions verified in the end

application.

• SDH2812 = Product code and size

• xxx= Inductance value in μH, R = decimal point,

If no R is present then 3^rddigit equals number of zeros.

• “-R” suffix = RoHS compliant

: Peak current for approximately 30% rolloff at +25°C.
