Environmental Conditions 4.1 Operating Temperature Range -10 o C ~ +70 o C 4.2 Storage Temperature Range -20 o C ~ +85 o C 4.3 Operating Humidity Range 10% ~ 85%(No water condenses in any cases.) 4.4 Storage Humidity Range 5% ~ 90%(No water condenses in any cases.) 3 5. Absolute Maximum Rating Item Unit Absolute Rating Remarks Maximum Input Voltage V +16 ON/OFF V +7 No voltage, no matter how instantaneous, shall be applied beyond the absolute maximum voltage rating to this product. If you apply any voltage over this limit the product characteristics will deteriorate or the product itself will be destroyed. Even though it may continue operating for a while after the over-voltage event, its life will likely be shortened significantly. Reliability and life of the module may degrade similarly if the maximum operating voltage rating is continuously exceeded. This product is designed to operate within the maximum operating voltage rating specification. 6. Characteristics 6.1 Electrical Characteristics (Ta=25 o C) Value Item Symbol Condition Min. Typ. Max.

15 Mounting Condition PCB Land Pattern Recommendation 2.5 1pin Area prohibits wirings other than land. There are wiring coppers or through-hole via at the bottom side of the DC-DC converter. When you design your PCBs, please be careful not to short the circuit of the DC-DC converter or PCBs.

16 Case surface temperature Recommendable Condition of Soldering Re-flow Soldering Please solder under the following condition. Method : Infrared ray re-flow soldering. Soldering temperatture : Case surface temperature 260 o C Max. Soldering time (Over 250 o C) : 20 seconds max (Case surface temperature) (Over 220 o C) : 30~75 seconds (Case surface temperature) Preheating Times : 60 ~150 seconds(150~200 o C) : 1time 20 seconds max. 260 Max ~150 seconds 30~75 seconds Colling curve 2~3 /seconds Soldering time Do not vibrate for the products on reflow. Please need to take care temperature control because mounted parts may come off if the product are left under the high temperature. Do not reflow DC-DC converter as follows, because DC-DC converter may fall down from a substrate during reflowing Substrate DC-DC Converter Recondition the soldering after re-flow Perform within 4 seconds while the temperature of soldering iron is 380 max., andit s power is 30W or less. Don t put the edge of soldering iron and solder on the pin of product, but put on the end of solder land.

17 14. Notice Both input-side and output side, please make the wiring loop between plus and minus as small as possible. The influence of leakage inductance can be reduced Please design the print pattern of the main circuit as wide and short as possible Please do not use a connector or a socket for connection with your board of this product. Electrical performance may be deteriorated the influence of contact resistance. Please be sure to mount this product with solder Be sure to provide an appropriate fail-safe function on your product to prevent a second damage that may be caused by the abnormal function or the failure of our product Inrush current protection is not a feature of this product Please connect the input terminal with proper polarity. If you connect wrong polarity, the DC-DC Converter may be broken. In the case of the DC-DC Converter is damaged, abnormal input current may flow in, and abnormal overheat of the DC-DC Converter, or some damage of your products may occur. Please use a diode and a fuse to as following figure. fuse + + diode IN OUT + Load - - Please select diode and fuse after confirming the operation Cleaning Please use no-cleaning type flux and do not wash this product Storage Please store the products in room where the temperature / humidity is stable direct sunlight cannot come in and use the products within 6 months after delivery. Avoid damp heated places or such places where there are large temperature changes, because water may condense on the products, the characteristics may be reduced in quality, and / or be degraded in the solder-ability. If you store the products for a long time (more than 1 year), use caution because the products may be degraded in the solder-ability and / or rusty. Please confirm solder-ability and characteristics for the products regularly 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).

18 14. 9 Operational Environment and Operational Conditions 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) 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 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 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. 18! Note 1. Murata recommends that customers ensure that the evaluation and testing of these devices are completed with this product actually assembled on their product. 2.
