Flow soldering

●

· We do not recommend fl ow soldering , because fl ow soldering may cause bridges between the electrodes.

<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 fl ux or halogen-free fl ux.

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 2 mode Noise Filters (hereafter called the fi lters) or pinch them with a hard tool (e.g. pli­ers and tweezers). Otherwise, their bodies may be chipped, affecting their performance. Excessive me chanical
stress may damage the fi lters. Handle with care.

4. Store the fi lters in a lo ca tion 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 fi lters within half a year after the date of the outgoing inspection indicated on the packages.
