TDK AVR-L Voltage Protection Chip Varistors
TDK AVR-L Voltage Protection Chip Varistors have no polarity due to symmetrical current-voltage characteristics equivalent to Zener diodes. The AVR-L Varistors offer exceptional electrostatic absorption capability with a response equal to, or better than, Zener diodes. These varistors maintain symmetrical current-voltage characteristics (even after electrostatic absorption) and are available in a 6.8V to 90V range.
Features
- No polarity due to symmetrical current-voltage characteristics
- Equivalent to an anode common type Zener diode
- Excellent electrostatic absorption capability
- Keeps symmetrical current-voltage characteristics even after electrostatic absorption
- Inner electrode lamination structure
- 27V to 90V range of varistor voltages available
- Low capacitance (from 1.1pF) items available
- 0402, 0603, 1005, 1608, 2012 chip sizes available
- Insulation resistance of 10RDC (MΩ) [3Vrms] minimum
- Excellent mount reliability
