= Tolerance of Inductance (M =
±20%,
N = +40%/-20%).
= Inductance value in uH (i.e. 3R5 = 3.5uH; 330 = 33uH; 331 = 330uH).
= Internal Control Code.
= Packaging Code (T = Tape & Reel Packaging in 13 inch Reel).
2. Test frequency is specified as the frequency for measuring the inductance.
3. Rated DC current is the saturation current or the heating current depending on which value is lower.
4. Isat: the saturation current indicates the value of DC current when the inductance is 25% lower than its initial value.
5. Heating current: is the value of current when the temperature rising

Notes:
7. The part temperature (ambient temperature + temperature rise) should not exceed the upper limit of the
operating temperature under worst case operating conditions. Circuit design, component placement, PWB
trace size and thickness, airflow and other cooling provisions all affect the part temperature. Part
temperature should be verified in the end application.
8. All dimensions are specified in inches with higher precedence in mm.
