Multilayer varistors (MLVs)
Controlled capacitance series
Features
ESD protection level acc. ISO 10605, IEC 61000-4-2
level 4
Bidirectional protection
Specified capacitance tolerance for additional EMI
filtering
Low insertion loss
Low leakage current
No signal distortion
RoHS-compatible
CT version suitable for lead-free soldering
Customer-specific types on request
Applications
For filtering purposes
at I/O ports (replacement of MLCC)
Design
Multilayer technology
Lack of plastic or epoxy encapsulation for
flammability rating better than UL 94 V-0
Termination (see “Soldering directions”):
CT and CA types with nickel barrier terminations
(AgNiSn), recommended for lead-free soldering,
and compatible with tin/lead solder.
V/I characteristics and derating curves
V/I and derating curves are attached to the data sheet.
The curves are sorted by V
RMS
and then by case size,
which is included in the type designation.
