■ Recommended Soldering Conditions
Recommendations and precautions are described below.
● Recommended soldering conditions for reflow
· Reflow soldering shall be performed a maximum of
two times.
· Please contact us for additional information when
used in conditions other than those specified.
· Please measure the temperature of the terminals
and study every kind of solder and printed circuit
board for solderability before actual use.

<Repair with hand soldering>
● Preheat with a blast of hot air or similar method. Use a soldering iron with a tip temperature of 350 °C or less. Solder
each electrode for 3 seconds or less.
● Never touch this product with the tip of a soldering iron.
Safety Precautions
The following are precautions for individual products. Please also refer to the precautions common to EMI Filters,
ESD Suppressors, Fuses, and MR Sensors shown on page EL113 of this catalog.
1. Chip EMI Filters (hereafter called the filters) cannot be mounted on a printed circuit board by flow soldering.
Mount them by reflow soldering.
2. Use rosin-based flux or halogen-free flux.
3. For cleaning, use an alcohol-based cleaning agent. Before using any other type, consult with our sales person
in advance.
4. Do not apply shock to the filters or pinch them with a hard tool (e.g. pliers and tweezers). Otherwise, their bodies
may be chipped, affecting their performance. Excessive mechanical stress may damage the filters. Handle
with care.
5. Avoid applying static electricity to the filters.
6. The performance of the filters deteriorates in a circuit that is susceptible to surges or other abnormal voltages.
Carefully check the circuit operations before use.
7. Store the filters in a location with a temperature ranging from –5 °C to +40 °C and a relative humidity of 40 % to 60 %,
where there are no rapid changes in temperature or humidity.
8. Use the filters within a year after the date of the outgoing inspection indicated on the packages.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.
