RECOMMENDED CIRCUIT

All the CTDD3120DF-D1.5K-3 Series have been tested according to the following recommended testing circuit before

leaving factory. This series should be tested under load (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.
