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

: Peak current for approximately 20% rolloff at +25°C.
5. K-factor: Used to determine B

6. Part Number Definition: HCMA1707-yyy-R
- HCMA1707 = Product code and size
- yyy= Inductance value in uH, R = decimal point,
if no R is present then third character = number of zeros.
- “-R” suffix = RoHS compliant
