features
Applications: CTDD1210DF-SU3K-1 Series is specially
designed for applications where a group of polar power supplies
are isolated from the input power supply in a distributed power
suppy system on a circuit board. These products apply to:
• Where the voltage of the input power supply is fixed (voltage
variation ≤ ±10%)
• Where the isolation is necessary between input and output
(isolation voltage ≤3000VDC)
• Where the regulation of the output voltage and the output rip-
ple noise are not demanding such as: purely digital circuits,
ordinary low frequency analog circuits, and IGBT power
device driving circuits.
Efficiency: To 79%
Isolation: 3KVDC
Miscellaneous: No heatsink required. No external component
required. Internal SMD construction. Industry standard pinout.
Additional Information: Additional electrical & physical
information available upon request.
Samples available. See website for ordering information.
