Safety Precautions
● The filter may fail in a short-circuit mode (or open-circuit mode) when subjected to severe conditions
of electrical and/or environmental stresses beyond their specified rating. Burnout or glowing may result in
the worst case.
● Soldering Flux: Use rosin type or nonhalogen type flux.
● Cleaning Solvent: Use alcohol based solution. Consult with us before using any other type of cleaning agent.
● Avoid contact with static electricity.
● Filter characteristics may deteriorate if subjected to surge or other abnormal voltage.
● Excessive mechanical stress may damage the components. Handle with care.
● Store under temperatures ranging from Ð5 ¡C to +40 ¡C and relative humidity from 40 % to 60 %. Avoid
rapid changes of temperature and humidity.
● Use the components within one year of delivery.
● Before ordering, test sample components in your application to ensure proper function and compatibility.
