Multilayer varistors (MLVs)
Low capacitance series
Features
ESD protection level acc. ISO 10605, IEC 61000-4-2
Level 4
Bidirectional protection
Low capacitance
Low insertion loss
Low leakage current
No signal distortion
RoHS-compatible
Suitable for lead-free soldering
PSpice simulation models available
Customer-specific types on request
Applications
ESD protection of data lines e.g. in notebooks and
portable devices
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.
