RECOMMENDED CIRCUIT
All the CTDD3120DF-T1K-3 Series have been tested according to the following recommended testing circuit before
leaving factory. This series should be tested under load. Never be tested under no load (See figure 1 & 2). If you want to
further decrease the input/output ripple, you can increase capacitance properly or choose capacitors with low ESR.
However, the capacitance should not be too high (See table 1). If you want to use the products in high EMI, please choose
our metal packaged products.
