TDK Corporation has expanded its tecchnical supp
port tools fo
or MLCCs: T
The new DC
C Bias
Mode
el enables designers
d
to
o simulate D
DC bias cha
aracteristics
s of MLCCss, even whe
en the DC
bias applied to the
t MLCCs varies. Tha
anks to TDK
K’s advance
ed electronicc component model,
the ccapacitance
e in the simu
ulation chan
nges dynam
mically with a changing DC bias vo
oltage, an
indusstry first*. Until
U
now, the available simulation libraries only offered m
models for one
o specificc
DC b
bias voltage
e at a time. The
T new DC
C Bias Mod
del is availab
ble in the H
HSPICE, LTs
spice and
PSpiice formats for the mos
st commonlyy used circu
uit simulator software aand can be
down
nloaded free
e of charge from the T DK Productt Center at
product.tdk.com
m/en/technic
calsupport/tvvcl/general//mlcc.html.
With its existing technical support
s
toolss for MLCC
Cs, TDK alre
eady providees data tha
at enable
the ssimulation of
o frequency
y characterisstics. Becau
use the effe
ective capaccitance of highperm
mittivity MLC
CCs (Class 2) changess when a DC
C voltage is applied, thee accurate simulation
of the
ese MLCCss in circuits must also rreflect their behavior when DC biaas voltage is
s applied.
For tthis reason, TDK’s dynamic electro
ronic compo
onent model is designeed to simula
ate both the
frequ
uency and DC
D bias cha
aracteristicss of MLCCs. Used toge
ether with thhe DC Supe

el, which en
nables the ssimulation of

new MLCC tool enhanc
ces the accuuracy of circuit
