Input External capacitor It is recommended to connect a low-impedance electrolytic capacitor of 40μF or more at Vin terminal. Smaller input capacitor may leads to an unstable operation of this product caused by input voltage fluctuation. Please check the proper operation of it on your product when smaller input capacitor is used. Using ceramic capacitors as input capacitor may cause an increase of output voltage, because input ripple current flows through the external input capacitor and wiring resistance. This phenomenon is affected by the position of external capacitors, the value of external capacitors and voltage difference between Vin and Vout. Using low-impedance electrolytic capacitor will ease this problem. Please check the proper operation of it on your product when ceramic input capacitor is used. MPDRX30*S Rw×Irpl appears as additional output ripple voltage. Vin Vout Cin Ripple current Rw Wiring resistance 7.9. Output External capacitor Ceramic capacitors are recommended as output external capacitor. Using ceramic capacitors, small output variation and small ripple voltage are realized. Output capacitor should be within 200μF to 2000μF. Output capacitor shall be placed near the output terminal. When using plural capacitors, please make sure to place a capacitor of at least 200μF near the output terminal, and place other capacitors near the load. When using LC output filter, please make sure to place a capacitor of at least 200μF near the output terminal. Note: 1. This datasheet is downloaded from the website of Murata Manufacturing co., ltd.

Please do not store this product in places such as : A dusty place, a place exposed directly to sea breeze, or in an atmosphere containing corrosive gas (Cl2,NH3,SO2,NOX and so on). 13.10. Operational Environment and Operational Conditions 13.10.1. Operational Environment The products are not waterproof, chemical-proof or rust-proof. In order to prevent leakage of electricity and abnormal temperature increase of the products, do not use the products under the following circumstances: (1) in an atmosphere containing corrosive gas (Cl2, NH3, SO2, NOX and so on). (2) in a dusty place. (3) in a place exposed to direct sunlight. (4) in such a place where water splashes or in such a humid place where water condenses. (5) in a place exposed to sea breeze. (6) in any other places similar to the above (1)through (5). 13.10.2. Operational Conditions Please use the products within specified values (power supply, temperature, input, output and load condition, and so on). Input voltage drop for line impedance, so please make sure that input voltage is included in specified values. If you use the products over the specified values, it may break the products, reduce the quality, and even if the products can endure the condition for short time, it may cause degradation of the reliability. Also please take care that the external voltage over output voltage of DC-DC Converter does not applies to output of this DC-DC Converter. Note: 1.
