!Caution/Notice
● Notice (Soldering and Mounting)
<Operating Environment>
Do not use products in a chemical atmosphere such as
chlorine gas, acid or sulfide gas.
Do not use products in the environment close to the
organic solvent.
<Storage and Handling Requirements>
1. Storage Period
NFM55P series should be used within 6 months, the
other series should be used within 12 months.
Solderability should be checked if this period is
exceeded.
2. Storage Conditions
(1) Storage temperature: -10 to +40˚C
Relative humidity: 30 to 70%
Avoid sudden changes in temperature and humidity.
(2) Do not store products in a chemical atmosphere
such as chlorine gas, acid or sulfide gas.
1. Cleaning
Failure and degradation of a product are caused by
the cleaning method. When you clean in conditions
that are not in mounting information, please contact
Murata engineering.
2. Soldering
Reliability decreases with improper soldering methods.
Please solder by the standard soldering conditions
shown in mounting information.
3. Other
Noise suppression levels resulting from Murata's EMI
suppression filters EMIFILr may vary, depending on
the circuits and ICs used, type of noise, mounting
pattern, mounting location, and other operating
conditions. Be sure to check and confirm in advance
the noise suppression effect of each filter, in actual
circuits, etc. before applying the filter in a commercial-
purpose equipment design.
1. Resin Coating
Using resin for coating/molding products may affect
the products performance.
So please pay careful attention in selecting resin.
Prior to use, please make the reliability evaluation with
the product mounted in your application set.
2. Caution for Use (NFW Series)
When you hold products with a tweezer, please hold
by the sides. Sharp materials, such as a pair of
tweezers, should not touch the winding portion to
prevent breaking the wire. Mechanical shock should
not be applied to the products mounted on the board
to prevent breaking the core.
Do not use products beyond the rated current and rated
voltage as this may create excessive heat and
deteriorate the insulation resistance.
• Self-heating
Please provide special attention when mounting chip
EMIFILr NFM_P series in close proximity to other
products that radiate heat.
The heat generated by other products may deteriorate
the insulation resistance and cause excessive heat in
this component.
