TDK Varistors(SMD) AVF16 Series Specifications

Varistors(SMD)
For High-speed Differential Signal Line
AVF16 Series
A low-voltage varistor applicable in high frequencies has been manufactured by using TDK circuit and material technology.
FEATURES
• Chip size: 1608 (L1.6× W0.8mm), applicable in 2 Line-in 1 (2in1)
differential line.
• 2GHz or more of cutoff frequency in differential mode (Sdd21).
• Superior electrostatic absorption characteristics due to reduction
of varistor voltage.
• Meeting Electrostatic Discharge Test IEC61000-4-2, HBM
(human body model) contact 8kV.
APPLICATIONS
• Protective circuit for high-speed differential signal from static
electricity
• HDMI, USB, IEEE1394, etc.
