Suffix “K” for 10% tolerance
Custom designs are available to meet your specific requirements; please contact factory.
*Add “LF” suffix for RoHS requirement. Example: SMP1812-101KLF
Gowanda designates a component RoHS-compliant by adding “LF” (lead free) to the part number.
These LF components meet the ≤ .1% lead requirement and they are compatible with 260°C soldering processes.

NOTES:
• Operating Temperature Range:
-55°C to +125°C
• Current Rating is based on a 40°C temperature
rise at an ambient temperature of 85°C
• Saturation Current is the approximate value
that will reduce the initial inductance by 5%
