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.
• DA53 Series combined with varistor or a cement resistor can be used as surge-protecting elements in power supplies.
