Notes:
1. Ordering Information: SIS1212a - bbbRc.
SIS1212 = Product Type.
= Tolerance of Inductance (M =
±20%).
a
= Inductance value in uH (i.e. 470 = 47uH; 471 = 470uH; 102 = 1000uH).
bbb
R
= Internal Control Code.
= Packaging Code (T = Tape & Reel Packaging in 13 inch Reel).
c
2. Inductance is tested at 0.25Vrms, 100kHz.
3. Saturation current, Isat, is the current at which the inductance of the component drops by 10% typical.

Notes:
4. Rated current, Irated, is the current required to raise the component temperature by approximately 40°C.
5. Operating temperature range: -40°C to +125°C.
6. 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.
