Dipped Radial Ceramic Capacitors
Mid Voltage FK Series
FEATURES
• Due to the technological progress in creating thinner layers of
ceramic dielectric and achieving multilayer lamination, this
product provides large electrostatic capacity.
• It maintains a high level of reliability under specified environ-
mental conditions.
• Its residual inductance is small and it provides good frequency
characteristics.
• The leads are formed with a "kink" to achieve consistent
insertion heights and facilitate the release of gases during
soldering for dramatically improved solderability.
• Also available are products that meet taping specifications for
automatic insertions, which contribute to reducing on-board
costs.
