CER SERIES | Controlled ESR
43
TDK’s CER multilayer ceramic chip capacitor series offers the unique
additional function of controlling the ESR (equivalent series resistance) value
as desired without affecting ESL (equivalent series inductance). This function
enables control of voltage change, which can occur between the power
source and the CPU, by controlling the impedance of the capacitors located
around the CPU.
The relatively low ESR value of standard MLCCs can be too low in
cases where the MLCC has replaced a Tantalum capacitors. Designer can
avoid the additional resistor typically used to solve this problem by utilizing
CER Series capacitors. This can contribute to cost saving due to less cost
during production. The mounting method of the CER Series is the same as
products with two terminals, which makes replacement of existing products
with CER chip capacitor very easy.

Features:
 Design allows for ESR to be controlled using unique
internal structure without affecting ESL
 Control of voltage variations eliminates effects on the
stability of current signals and impact on other circuits
 Same mounting method as 2-terminal components
 Flatness of impedance characteristics is enhanced
through additional resistance components, reducing the
number of components by 50%
