: For Power line
(ZnO:Zinc Oxide)
(ST:Strontium Titanate)
(Small capacitance)
(High capacitance)
n Construction
n Features
l Multilayer monolithic construction of ceramics
l Excellent solderability and superior heat resistance
l Large withstanding surge current and energy
capabilities at small size
l Series EZJZ
l Multilayer varistor of Zinc oxide ceramics
suppresses pulse noise (ESD, burst-noise) and
protects equipment from transient surges.
l This Varistor is suitable for high-speed signal lines
due to small capacitance.
l Series EZJS
l Multilayer varistor of Strontium Titanate ceramics
suppresses the pulse noise, especially high frequency noise(ESD, burst-noise) and protects the
equipment from the transient surge.
l This Varistor is suitable for low-frequency signal
circuit(power and audio signal line) due to large
capacitance.
