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
μH the R indicates a
decimal point and the remaining digits indicate the
inductance in
μH. For values 10μH and above, the first
two digits indicate the inductance in
μH 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
μH)
1R2
Example: SPD74R-105M (1,000
μH)
