with heat shrink covering; or x =

without heat shrink covering).
= Tolerance of Inductance (M =
±20%;
K =
±10%).
= Inductance value in uH (i.e. 3R3 =3.3uH; 330 = 33uH; 331 = 330uH; 102 = 1000uH).
= Internal Control Code.
= Packaging Code (No code = Non Tape & Reel Packaging, i.e. Tray packaging).
2. Test frequency is specified as the frequency for measuring the inductance and Q value.
3. Operating temperature range: -40°C to +125°C.
4. 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.
