- ※ Note: 1. When the input voltage is 230VAC, the PCB type (Blank-Type) model delivers EMI Class B  for both conducted emission and radiated emission for the power supply; When the input voltage is 110VAC, the PCB type (Blank Type) model delivers EMI Class B  for conducted emission and Class A for radiated emission for the power supply. It delivers Class A for conducted emission and radiated emission, when configured into ClassⅡ (no FG) system. 

   2. The enclosed type (-C/TF/SF type) models are not suitable for configuration within a ClassⅡ (without FG) system, but suggested  within a ClassⅠ(with FG) system. 

   3. Mounting Instruction for enclosed type.

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →
Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
