The following are precautions for individual products. Please also refer to the precautions common to EMI Filters,
Fuses, and Sensors(MR Elements) shown on page EX2 of this catalog.
1. With regard to fl ow soldering, consult with our sales person in advance.
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 per son
4. Do not apply shock to Chip Bead Cores (hereafter called the bead cores) or pinch them with a hard tool (e.g.
5. Store the bead cores in a location with a temperature ranging from -5 °C to +40 °C and a rel a tive humidity of
6. Use the bead cores within a year (EXC3B Type: within half a year) after the date of the out go ing in spec tion
