SMD Device
1 Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.10Vrms, 0.0Adc
2Irms: DC current for an approximate temperature rise of 40°C without core loss. Derating is
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.
3Isat: Peak current for approximately 30% rolloff at +25°C.
4 K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * ΔI. Bp-p (Gauss),
K: (K-factor from table), L: (inductance in
μH), ΔI (peak-to-peak ripple current in amps).
5 Part Number Definition: SDH2812-xxx-R
SDH2812 = Product code and size
xxx= Inductance value in
μH, R = decimal point,
If no R is present then 3
rd digit equals number of zeros.
“-R” suffix = RoHS compliant
