Product Information

High-voltage ceramic capacitor engineering

Evaluate the electric field, dielectric behavior and physical spacing together

This 15kV 472M high-voltage ceramic capacitor is a 0.0047µF (4.7nF) selection starting point. Final approval must identify whether the stated voltage is DC, AC or impulse-related and must align dielectric class, capacitance tolerance, frequency, temperature, lead geometry, coating and insulation clearances.

Voltage duty

Define continuous, peak, pulse and transient voltage, waveform, repetition rate and required design margin.

Dielectric behavior

Confirm dielectric class, capacitance change with voltage and temperature, loss, frequency response and aging behavior.

Physical insulation

Review body size, lead spacing, lead length, coating, creepage, clearance, potting and surrounding conductive parts.

Why headline voltage is not enough

15kV components can face very different electrical stress

A ceramic capacitor used on a steady DC bias is not automatically suitable for repetitive pulses, high-frequency AC or high-energy discharge. Electric-field distribution, partial-discharge risk, corona environment, dielectric heating, dv/dt, lead inductance and mounting geometry can change the result even when the printed voltage and capacitance match.

Bias and filtering

Review continuous voltage, ripple, frequency, temperature and capacitance change under applied bias.

Pulse and discharge circuits

Define peak voltage, pulse width, repetition rate, stored energy, dv/dt and damping conditions.

Replacement qualification

Cross-reference the original dielectric, outline, lead spacing, coating, voltage definition and test conditions—not the marking alone.

Qualification workflow

Six checks before approving a high-voltage ceramic capacitor

1. Classify the waveform

DC, AC, pulse or mixed duty; continuous, peak and transient levels; frequency and repetition rate.

2. Confirm the dielectric

Dielectric class, tolerance, temperature behavior, voltage coefficient, loss and aging requirements.

3. Check energy and heating

Stored energy, discharge path, dv/dt, reactive current, dielectric loss and permitted temperature rise.

4. Lock the geometry

Body diameter and thickness, lead spacing and length, coating, mounting orientation and clearance.

5. Approve samples

Capacitance, tolerance, insulation behavior, dissipation, fit, soldering and application stress testing.

6. Control repeat supply

Selected series, drawing, marking, lead form, inspection, packing, traceability and change requirements.

Layout and safety review

Clearance, coating and mounting are part of the electrical design

Creepage and clearance

Determine spacing from the equipment voltage, pollution degree, insulation system, altitude and applicable safety design.

Coating and environment

Review humidity, contamination, potting or conformal coating, sharp conductors and corona-prone geometry.

Lead and soldering stress

Avoid forcing lead spacing, bending too close to the body or transferring mechanical load into the ceramic element.

Discharge protection

Provide safe discharge, current limiting and access control appropriate to the stored energy and equipment architecture.

Ordering information

Send the waveform and insulation constraints with the RFQ

A complete request lets engineering review the real high-voltage duty instead of approving from the 15kV 472M marking alone.

Electrical waveformDC, AC or pulse; continuous and peak voltage; frequency, pulse width, repetition and transients

Capacitance requirement4.7nF nominal starting point, tolerance, dielectric behavior and permitted drift

Mechanical interfaceBody envelope, lead spacing and length, lead form, mounting and soldering process

Insulation environmentCreepage, clearance, altitude, humidity, contamination, potting and surrounding conductors

Commercial programSample, order and annual quantities, marking, packing, documentation and delivery needs

Documents and approval basis

Release against the selected series and its test conditions

Request the current controlled datasheet, dimensional drawing, dielectric information, voltage definition and test method, lead-form reference, packing specification and order-specific compliance records.

Final approval basis: controlled datasheet, controlled drawing, quotation and approved sample. The marking 15kV 472M alone does not establish suitability for AC, pulse or safety-critical service.

Frequently asked questions

Questions to resolve before sample approval

Does 15kV mean the same thing for DC, AC and pulse operation?

No. The voltage definition, waveform, frequency, duration, repetition and test conditions must match the selected series.

What does 472M indicate?

The existing product record identifies 0.0047µF (4.7nF) and an M tolerance class; confirm the controlled datasheet and marking convention before release.

Can two capacitors with the same marking be interchangeable?

Not automatically. Dielectric, body size, lead spacing, coating, voltage definition, loss and pulse behavior may differ.

What should sample testing include?

Check capacitance, tolerance, insulation behavior, loss, physical fit, soldering and performance under the actual voltage waveform and environment.

Can the lead spacing be changed?

Lead form and spacing may be reviewed, but mechanical changes require an approved drawing and must preserve electrical clearances and ceramic integrity.

What determines MOQ and lead time?

The selected series, voltage duty, geometry, lead form, quantity, testing, marking, documentation and packing determine the result.
