CU Types Medium Voltage MLV Multilayer SMD Metal Oxide Varistor MOV 3225 4032 270V 360V 430V 470V 510V 560V 620V 680V
SMD varistors, which are alsoknown as CU varistors, are ceramicsemiconductor components forsurge current protection in consumer, industrial, automotive andtelecom applications. SMD varistorsare encapsulated componentsdesigned for SMD mounting andare electrically equivalent to the 07D leaded disk varistors (diskdiameter 7 mm) in case size 3225 and 10D (disk diameter 10 mm)in case size 4032.The varistors cover a voltage rangefrom 14 to 385 V DC and are designed for surge currents of between 1250 and 2500 A at a standard pulseof 8/20 μs.
The medium voltage varistors is designed to protect electronic equipmentagainst high voltage surges in the medium voltage region. They offer excellent transientenergy absorption due to improved energy volume distribution and power dissipation.
- Three model sizes available - 3255, 4032and 2220 (available on request)
- Leadless chip form - zero inductancefacilitating extremely fast response time totransient surgesn
- Broad range of current and energy handlingcapabilities
- +125 °C Continuous operating temperature
- Tolerant of common water cleaningprocedures and humidity (climatic category55/125/56)
- Available in tape and reel packaging forautomatic pick-and-place
- SMD mountable varistors,suitable for lead-free soldering
- Bidirectional protection in asingle componentz High surge current capability to IEC 61000-4-5 for the telecomseries
- Jump start and load dumpprotection to ISO 7637, pulse 5for automotive series
- Construction--> Disk varistor element with thermoplast encapsulation (flame-retardantto UL 94 V-0) in case sizes 3225and 4032.
