Multilayer varistors (MLVs)
Radio frequency series
Features
Ultra-low capacitance ratings down to 0.6 pF
Ultra-low DC leakage current
Low insertion loss
No signal attenuation
ESD protection acc. to IEC-61000-4-2 level 4
Extremely fast response
RoHS-compatible
Suitable for lead-free soldering
Applications
ESD protection in mobile phones, handheld devices
and wireless LAN/notebook and peripherals:
RF antennas
RF modules
High-speed data lines
