■ 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.

Flow soldering
●
· Flow soldering may cause this product to come off because the adhesiveness of the product element is low.
Please consult our sales representative in advance about flow soldering.
<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 common precautions for Noise Suppression
Device shown on this catalog.
1. Use rosin-based flux or halogen-free flux.
2. For cleaning, use an alcohol-based cleaning agent. Before using any other type, consult with our sales person
in advance.
3. Do not apply shock to Chip Bead Cores (hereafter called the bead cores) 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 bead cores. Handle with care.
4. Store the bead cores 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.
5. Use the bead cores within a year (EXC3B Type: within half 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.
