■ Features
• Small size. (ø3.8mm Length 10mm)
• Allows performing the AC withstanding voltage test.
• Quick response for surge voltage, and low limiting voltage.
• Small capacitance and excellent insulation resistance.
• Stable for repeated electrostatic test conditions and environmental fluctuation.
• Axial taping available.
• No polarity.
• No dark effect.
• DA38 Series combined with varistor or a cement resistor can be used as surge-protecting elements in power supplies.
