Input External capacitor It is recommended to connect a low-impedance electrolytic capacitor of 20μF 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 Vin Cin Vout Ripple current Rw×Irpl appears as additional output ripple voltage. 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 100μF to 1000μF. Output capacitor shall be placed near the output terminal. When using plural capacitors, please make sure to place a capacitor of at least 100μF 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 100μF near the output terminal. Note: 1. This datasheet is downloaded from the website of Murata Manufacturing co., ltd.

Notice 14. 1 Both input-side and output side, please make the wiring loop between plus and minus as small as possible. The influence of a leakage inductance can be reduced. 14. 2 Please make the power line pattern as wide and short as possible. 14. 3 This product should not be operated in parallel or in series. 14. 4 Please do not use a connector or a socket to connect this product to your product. The electric characteristics may be deteriorated by the influence of contact resistance. 14. 5 Be sure to provide an appropriate fail-safe function on your product to prevent secondary damage that may be caused due to abnormal functional or failure of this product. 14. 6 Inrush current protection is not a feature of this product. 14. 7 Please connect the input terminals with the correct polarity. If an error in polarity connection is made this product may be damaged. If this product is damaged internally, an elevated input current may flow, and so this product may exhibit an abnormal temperature rise, or your product may be damaged. Please add a diode and fuse per the following diagram to protect them. fuse + + + diode IN - OUT Load - ※Please select diode and fuse after confirming the operation of your product. 14. 8 Cleaning Please use no-cleaning type flux and do not wash this product. 14. 9 Storage Please store the products in room where the temperature/humidity is stable and direct sunlight cannot come in, and use the products within 6 months after delivery. Please avoid damp and heat or such places where the temperature greatly changes, as water may condense on this product, and the quality of characteristics may be reduced, and/or be the solderability may be degraded. If this product needs to be stored for a long time (more than 1 year), this product may be degraded in solderability and/or corroded. Please test the solderability of this product regularly. Baking before reflow process is unnecessary to store the products under 30℃,60%RH or less up to 6 months. In case the storage condition is over above mentioned, if these are unpacked condition, please bake them at 125℃±5℃/24hour. 14. 10 Please do not store the products in the places such as in a dusty place, in a place exposed directly to sea breeze, in an atmosphere containing corrosive gas (Cl2,NH3,SO2,NOX and so on).

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). 14.11.2 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. 14.11.3 Note prior to use If you apply high static electricity, over rated voltage or reverse voltage to the products, it may cause defects in the products or degrade the reliability. Please avoid the following items: (1) over rating power supply, reverse power supply or not-enough connection of 0 V(DC) line. (2) electrostatic discharge by production line and/or operator. (3) electrified product by electrostatic induction. Do not give an excessive mechanical shock.. If you drop the products on the floor, etc., it may occur a crack to the core of inductors and monolithic ceramic capacitors. Do not give a strong shock such as a drop in handling. 14. 12 Transportation If you transport the products, please pack them so that the package will not be damaged by mechanical vibration or mechanical shock, and please educate and guide a carrier to prevent rough handling. If you transport the products to overseas (in particular, by sea), it is expected that the transportation environment will be the worst, so please pack the products, in the package designed on the consideration of mechanical strength, vibration-resistant and humidity-resistant. The package of the products which Murata sells in Japan, may not resist over seas transport. Please consult us if you are to use the Murata package of the products sold in Japan for transport to overseas. ! Note １.
