※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.

13. Notice
13.1. 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.
13.2. 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.
13.3. Input / Output capacitor
When a inductance or a switch devise are connected to the input line, or when you use a power supply with
output inductance as the input voltage source, the input voltage of the DC-DC converter will be fluctuated.
By this input voltage fluctuation, the transient load response of the DC-DC converter may be deteriorated or
abnormal oscillation may occur. So please confirm normal operation on each application.
Please use external input capacitor in order to decrease inductance of input line.
13. 4. Wiring of input / output capacitor
In the case of input / output capacitor connection, in order to reduce electrical noise, please design PCBs
with consideration of the following item.
①.Please be sure to check normal operation on your system.
②.Please use low impedance capacitors with good high frequency characteristic.
③.Please shorten those leads of each capacitor as much as possible, and make sure the lead
Inductance low.
④.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.
⑤.Please design the print pattern of the main circuit as wide and short as possible.

13.5. This product should not be operated in parallel or in series.
13.6. Inrush current protection is not a feature of this product.
Please be careful that surge voltage caused by wiring indcutance etc. may make the product damage when input
voltage is applied suddenly to the product.
13.7. 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.

13.8. Cleaning
Please use no-cleaning type flux and do not wash this product.
13.9. Storage
13.9.1. 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
condenseon 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. If these are packed in a tape, please bake them before soldering at
60℃±5℃/168hour.
13.9.2. 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.
13.10.3. 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.
13.11. 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.
