DA53 Series has a micro gap cut to an accuracy of several tens of microns in width for rapid response against induced lightning and electrostatic discharges.
Allows performing the AC withstanding voltage test.
This series are ideal for protecting power supplies against surge voltage.
■ Features
• Small size. (ø5.3mm
Length 10mm)
• Allows performing the AC withstanding voltage test.
• Used to protect power supplies.
• Quick response for surge voltage, and low limiting voltage.
• Small capacitance and excellent insulation resistance.
• Stable for repeated electrostatic test conditions and environmental fluctuation.
• No polarity.
• No dark effect.
