Product Description
High Surge Type Multilayer Chip Varistor 2220 5650 5750 85V 4500A
Designed for surge current suppression in communication equipment, this high-performance multilayer chip varistor provides reliable overvoltage protection with nanosecond response times.
Product Overview
Zinc oxide varistors are polycrystalline semiconductor ceramic elements made primarily from zinc oxide with various metal oxide additives. These voltage-limiting protection devices connect in parallel with protected circuit elements, rapidly clamping transient overvoltages to safe levels within nanoseconds to prevent circuit damage from lightning strikes, electrostatic discharge, or operational transients.
Key Features
- SMD compact design saves space and simplifies production
- Nanosecond response time meets diverse circuit protection requirements
- Superior surge suppression capacity compared to TVS devices
- Stable high-temperature performance with no derating at 125°C
- Low leakage current (IL < 10μA)
- Bidirectional non-polar protection with low clamping voltage
- UL94V-0 flammability rating compliance
- RoHS environmental standards compliance
Applications
- Automotive electronics: control units, electro-hydraulic brakes, ABS/ESP systems, sunroof and window controls
- Industrial instrumentation, control systems, measurement equipment, security cameras, electronic meters
- 5G communication base stations, network equipment, network interfaces, protector control boards
- ESD protection for audio/video I/O ports, high-speed data lines (HDMI, USB 3.0, IEEE 1394), RF antennas and modules
- Compliance with IEC 61000-4-5 surge protection, IEC 61000-4-4 EFT protection, and IEC 61000-4-2 ESD protection (Level 4)
