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. Design, Specifications are subject to change without notice. Ask factory for technical specifications before purchase and/or use.
