Notes:
1. Ordering Information: RIS7532A - bbbaFc.
RIS7532A = Product Type.
= Tolerance of Inductance (M =
± 20%).
a
bbb
F
= Inductance value in uH (i.e. 151 = 0.15uH; 152 = 1.5uH).
c
2. Inductance is tested at 100mVrms, 100kHz .
= Internal Control Code.
= Packaging Code (T = Tape & Reel Packaging in 13 inch Reel).
3. Saturation current, Isat, indicates the value of DC current when the inductance is 30% (typical) lower than its
initial value at an ambient temperature of 25°C.
4. Heating current, Irms, is the current required to raise the component temperature by approximately 40
o
C. The
heating current is determined by mounting the component on a typical PCB and applying current for 30 minutes.
5. Operating temperature range: -40
o
C to +125
o
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.
