Recommendations and precautions are described below.
<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
● Never touch this product with the tip of a soldering iron.
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. When possible, do not mount Chip Bead Array (hereafter called the bead arrays) by fl ow soldering. It is highly
2. Use rosin-based fl ux or halogen-free fl ux.
3. For cleaning, use an alcohol-based cleaning agent. Before using any other type, consult with our sales person
4. Do not apply shock to the bead arrays or pinch them with a hard tool (e.g. pliers and tweezers). Otherwise, their bodies
5. Store the bead arrays in a location with a temperature ranging from –5 °C to +40 °C and a relative humidity of 40 % to
6. Use the bead arrays within half a year after the date of the out go ing inspection indicated on the packages.
