CHIP VARISTOR FEATURES
•
•
•
•
•
•
•
SMD type chip varistors are highly reliable in surface mount applications.
Wide operating voltage range.
Large withstanding surge current and energy at small size
Suitable for high speed signal line due to small capacitance
Excellent solderability and superior heat resistance
Ag base terminal electrodes with Ni + Sn-Pb electroplating
No asymmetrical degradation as with bismuth zinc oxide varistors
CHIP VARISTOR APPLICATIONS
Typical Applications:
Information and communication equipment
Signal line of cellular phones
Transient voltage protection for ICs and transistors
ESD and I/O protection
Overall telecommunication transient protection

HIGH SPEED TYPE CHIP VARISTORS
•
Typical ESD failure voltage for CMOS and/or Bi Polar is
≥200V.
• 15kV ESD pulse (air discharge) per IEC 1000-4-2.Level 4, generates <2OmJ of energy.
• Low capacitance (<200pF) is required for high-speed data transmission.
• Low leakage current(l
L
) is necessary for battery operated equipment.
