product.
Please provide special attention when mounting chip
common mode choke coils 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.
PLT10H series should be used within 12 months.
Solderability should be checked if this period is

Bending
Mount Chip Common Mode Choke Coils in right
direction. Wrong direction, which is 90 degrees
rotated from right direction, causes not only open or
short circuit but also flames or other serious trouble.
Notice (Soldering and Mounting)
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.
Reliability decreases with improper soldering methods.
Please solder by the standard soldering conditions
shown in mounting information.
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
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.
