Mechanical Configuration
Units designed for surface
mounting; ferrite core and ferrite sleeve
Operating temperature range
–55°C to +125°C
Application Frequency Range
Values 1.2µH to 10µH to 1.0 MHz Min.
Values above 10µH to 300 kHz Min.
Current Rating at 25°C Ambient
The maximum DC
current that will cause a 40°C maximum temperature rise
and where the inductance will not decrease by more than
10% from its zero DC value
Marking
For values lower than 10 H the R indicates a
decimal point and the remaining digits indicate the
inductance in H. For values 10 H and above, the first two
digits indicate the inductance in H and the third digit
indicates the number of trailing zeros where a zero
indicates that there are no trailing zeros.
Example: SPD73R-122M (1.2 H)
1R2
Example: SPD74R-105M (1,000 H)
