Ringing is caused on the signal waveform.
Such ringing contains several hundred MHz harmonic components and generates noise.
Signal waveform (100nsec/div, 2V/div) Expand (10nsec/div, 2V/div) Spectrum
Comparing initial waveform, ringing is suppressed a little.
However there still remains high level waveform distortion.
Signal waveform (100nsec/div, 2V/div) Expand (10nsec/div, 2V/div) Spectrum
BLM18R has excellent performance for noise suppression and waveform distortion suppression.
BLM18R suppresses drastically not only spectrum level in more than 100MHz range but waveform distortion.

Chip Ferrite Bead !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: 15 to 85%
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
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.
!Caution
Notice
2. Handling of a Substrate
After mounting products on a substrate, do not apply
any stress to the product caused by bending or
twisting to the substrate when cropping the substrate,
inserting and removing a connector from the substrate
or tightening screw to the substrate.
Excessive mechanical stress may cause cracking in
the Product.

2. Solder Paste Printing and Adhesive Application
When reflow soldering the chip ferrite beads, the printing
must be conducted in accordance with the following
cream solder printing conditions.
If too much solder is applied, the chip will be prone to
damage by mechanical and thermal stress from the PCB
and may crack.
Standard land dimensions should be used for resist and
copper foil patterns.
When flow soldering the chip ferrite beads, apply the
adhesive in accordance with the following conditions.
If too much adhesive is applied, then it may overflow into
the land or termination areas and yield poor solderability.
In contrast, if insufficient adhesive is applied, or if the
adhesive is not sufficiently hardened, then the chip may
become detached during flow soldering process.

3. Standard Soldering Conditions
(1) Soldering Methods
Use flow and reflow soldering methods only.
Use standard soldering conditions when soldering chip
ferrite beads.
In cases where several different parts are soldered, each
having different soldering conditions, use those
conditions requiring the least heat and minimum time.
Solder: Use Sn-3.0Ag-0.5Cu solder. Use of Sn-Zn based
solder will deteriorate performance of products.
If using BLA series with Sn-Zn based solder,
please contact Murata in advance.
Flux:
o Use Rosin-based flux.
In case of using RA type solder, products should be
cleaned completely with no residual flux.
o Do not use strong acidic flux (with chlorine content
exceeding 0.20wt%)
o Do not use water-soluble flux.
For additional mounting methods, please contact Murata.
!Note Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc.
