EFH SERIES

High Frequency Multilayer Chip Inductors
EFH SERIES

FEATURES

  • The EFH series is designed for high frequency application up to GHz band circuit due to low inductance.
  • High SRF exhibits high Q value at high frequency.
  • Monolithic inorganic material construction for high reliability.
  • Excellent for high frequency RF applications such as cellular phones, pagers, PDAs, computer communications, etc..
