!Caution/Notice
1. About the Rated Current
Do not use products beyond the rated current as this
may create excessive heat and deteriorate the
insulation resistance.
2. About the Excessive Surge Current
Excessive surge current ( pulse current or rush
current) than specified rated current applied to the
product may cause a critical failure, such as an open
circuit, burnout caused by excessive temperature
rise. Please contact us in advance in case of
applying the surge current.
● Soldering and Mounting
• Self-heating
Please provide special attention when mounting chip
ferrite beads BLM_AX/P/K/S 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.
● Rating
● Storage and Operating Conditions
● 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
BLM15E/15H/15G series should be used within 12
months, the other series should be used within 6
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.
● Handling
• 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.
