Overview
With the rapid development of technology, electronic products are showing a trend of miniaturization. The traditional leaded varistor has been unable to meet the requirements of AC power line.For low-power LED lighting, high-voltage linear driverand AC direct driver solution become a trend, where chip varistor is the main lightning protection component. SVMH series are produced with multilayer technology, can be used in 110V or 220V AC power line for voltage surge suppression.
Background
- Based on miniaturization trend of varistor for AC power supply
- Chip varistor for AC power supply is strongly demanded in high-end LED lighting and power adapter.
- To replace traditional leaded varistor in situations with height limit.
Features
- SMD type,suitable for high density mounting
- Compared with SDVL series, chip varistor applications expand to AC power lines
- High surge current suppression capability
- High surge energy absorbing capability
Applications
- Low-power LED lighting
- Ultra-thin adapter
- Situations with height limit.
