Ceramic Resonators (CERALOCK)Base Metal Electrode CERALOCK

This is a new CERALOCK which was constructed by utilizing base metal electrode technology.

Features

  1. Since precious metals (Palladium) are not used, a long-term stable supply is possible.
  2. The electrical characteristics and environmental resistances are equivalent to previous products.
  3. The same land pattern as previous products allow the component to be replaced without changing the design of a board.
    • *Except for some series.

Q&A

AThis is to prevent potential supply risks and price increases, by changing the material from the precious metal palladium to nickel.
AIt is not necessary. However, when changing the IC and or board layout, we recommend another IC matching evaluation be conducted.
AIt is not necessary unless the previous product falls under the CSCTE_V or CSTCE_V_A series. See below for changes.
