: 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.

Part Number Definition: RL1218-yyy-R
- RL1218 = Product code and size
- yyy= Inductance value in μH, R = decimal point,
if no R is present then third character = number of zeros.
- “-R” suffix = RoHS compliant
