1. Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.25 Vrms, 0.0 Adc,
+25 °C.
2. Full Load Inductance (FLL): Test parameters: 100 kHz, 0.25 Vrms, Isat, +25 °C.
3. Irms: 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.. Isat : Peak current for approximately 20% rolloff at +25 °C.
5. K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * I.
Bp-p :(Gauss), K: (K-factor from table), L: (Inductance in μH), I (Peak to peak
ripple current in amps).
6. Part Number Definition: HCMA1707-yyy-R
- HCMA1707 = Product code and siz
yyy= Inductance value in uH, R = decimal point,
if no R is present then third character = number of zeros.
-“-R” suffix = RoHS compliant

wwllyy R
All soldering surfaces coplanar within 0.10 millimeters.
Part marking: HCMA1707; A = Automotive grade, XXX = initial inductance in µH, R = decimal point;
if no R is present, last digit equals number of zeros.
wwllyy = date code, R = revision level
