Frequently Asked Questions (FAQ)
Q1: What is a self-healing metallized electrode pulse capacitor?
It is a type of capacitor where the dielectric film is coated with a microscopic metal layer. If a localized electrical breakdown occurs, the metal layer around the breakdown point evaporates instantly due to the arc heat, isolating the fault and restoring the capacitor's functionality.
Q2: What are the primary applications of these pulse capacitors?
They are widely used in demanding high-energy applications including Magnetizers/Demagnetizers, medical equipment, high-voltage impulse generators, high-power pulse power supplies, high-energy accelerators, thermonuclear reaction test devices, and intense laser systems.
Q3: Can the dimensions and electrical specifications be customized?
Yes, our PKMJ series pulse capacitors are custom-made upon request. We can adjust the rated voltage, capacitance range, peak current, inductance, and overall dimensions to match your specific system requirements.
Q4: What is the operating temperature range for these capacitors?
The standard operating temperature range is -20°C to +65°C. For specialized high-temperature applications, custom designs supporting operating temperatures of ≥85°C are available.
Q5: Why is a metal housing used instead of plastic?
The fully-sealed metal housing provides superior structural integrity, reliable non-inductive winding core protection, excellent moisture proofing, and enhanced heat dissipation, which ensures a long lifetime and high reliability under extreme conditions.
