RECOMMENDED CIRCUIT
All the CTDD2709SF-T1K-1 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). 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 2). If you want to use the products in high EMI, please choose our metal packaged
products.
