Remarks
※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, it’s 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.

Caution
・The above electrical characteristics are guaranteed with the condition that the impedance of the input voltage source is sufficiently low
as shown in section 10. Connecting an input inductance or using an input power supply with output inductance may cause an unstable
operation of this device. Please check the proper operation of this device with the peripheral circuits on your system.
・It is strongly recommended that on/off terminal should be used when you turn on/off this product. Characteristics may be affected
by turning input voltage on/off. Please check product operation on your application with turning input voltage on/off.
・This product has wide input voltage range, but , the large input voltage rapid change may cause the large output voltage change and
protection circuit malfunction. So, please check your input voltage specification in your product application.
・That the over-current protection circuit of a product operates according to the incoming current to an output capacitor at the time
of ON of this product it is. It is wished the following formula restricts the output current at the time of the product ON to a standard.
Start-up output possible current formula
Cout(mF) × Vout(V)
Io(START)
(A)=Iocp(A) - T(START(ms)
)
Where
Io(START):Start-up possible output current
Cout: Output Capacitance ,
Vout:Output Voltage
T(START):Startup Time ,
Iocp:OCP Threshold Current
Example about worst case calculation
T(START)=0.5(ms), Cout=2(mF), Iocp=20A(4.5V≦Vin<10V), 26A(10V≦Vin≦14V)

12.2 Cleaning
12.2.1 Please clean them to remove flux from them using the dipping, boiling, and vapor methods in isopropyl alcohol for up to 5 minutes.
Please inform us if you are to use aqueous or semi-aqueous cleaning or another methods.
Do not use ultrasonic cleaning because semiconductor device on the products, bonding wires may be broken by resonance.
12.2.2 After cleaning, please dry the products thoroughly. If you touch the products that have not been dried enough yet,
you need to take care because the marking of the products may get thin or blurred.
Do not measure electrical characteristics, until the products get dried enough.
12.2.3 If you use no-cleaning type flux and you don’t clean our products, you must confirm the reliability of the products fully in advance.
12.3 Storage
12.3.1 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.
12.3.2 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).
Note:
1. This datasheet is downloaded from the website of Murata Manufacturing co., ltd. Therefore, it’ s specifications are subject to change or our
products in it may be discontinued without advance notice. Please check with our sales representatives or product engineers before ordering.
2. This datasheet has only typical specifications because there is no space for detailed specifications. Therefore, please approve our product

12.4 Operational Environment and Operational Conditions
12.4.1 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).
12.4.2 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.
12.4.3 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.
12.5 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.
