Product Information

Screw Terminal Capacitor Engineering

Built for high-energy bus service and bolted connections

This 2200µF / 250V screw-terminal aluminum electrolytic capacitor is a selection starting point for industrial power conversion and energy-storage duty. Final release must coordinate electrical stress, ripple heating, can dimensions, terminal interface, mounting, ventilation and service-life requirements.

Electrical duty

Confirm working voltage, surge, discharge cycle, ripple spectrum, fault conditions and the required capacitance window.

Thermal duty

Evaluate ambient, cooling path, self-heating, duty cycle, nearby heat sources and the application life target.

Mechanical and safety

Match can size, terminal spacing, polarity, mounting method, vent clearance, insulation and connection hardware.

Why the format matters

High-current connections need more than a matching headline rating

Screw-terminal construction supports robust busbar or cable connections in high-energy equipment. The same capacitance and voltage do not guarantee interchangeability: ripple capability, ESR, thermal resistance, surge behavior, can geometry, terminal layout, mounting, venting and approved tightening conditions must be reviewed together.

Drives and inverters

Review DC-bus voltage, regeneration, harmonic ripple, load cycle, enclosure temperature and cooling.

Industrial power supplies

Check hold-up demand, charge current, surge events, parallel-bank sharing and protection strategy.

Replacement programs

Cross-reference the original datasheet, outline drawing, terminal pattern and installation constraints before approval.

Qualification workflow

Six checks from circuit requirement to repeat supply

1. Define the bus

Working voltage, surge, discharge profile, ripple waveform, frequency and fault limits.

2. Calculate heating

Ripple by frequency, ESR or impedance, ambient, cooling and temperature-rise allowance.

3. Lock the outline

Diameter, height, terminal spacing, polarity, stud type, mounting and vent clearance.

4. Align installation

Busbar or cable interface, insulation, creepage, hardware and tightening instructions from the controlled drawing.

5. Approve samples

Capacitance, leakage, ripple heating, mechanical fit, connection stability and discharge behavior.

6. Control supply

Series, drawing, marking, inspection, packing, lot traceability and change requirements.

Installation and safety

Plan connection, clearance, ventilation and discharge before release

Terminal connection

Use the approved hardware and tightening value from the controlled drawing; do not infer torque from appearance.

Polarity and spacing

Confirm terminal identification, creepage and clearance, insulation barriers and busbar geometry.

Vent and mounting

Keep the pressure-relief area unobstructed and follow the approved mounting orientation and restraint method.

Stored energy

Provide discharge, lockout and verification measures appropriate to the equipment and capacitor bank.

Ordering information

Send engineering and commercial requirements together

A complete RFQ lets engineering and sales review the same application without repeated clarification.

Documents and approval basis

Release against controlled evidence

Request the current controlled datasheet, outline drawing, terminal and mounting details, installation instructions, inspection reference and order-specific compliance records for the selected series.

Final approval basis: controlled datasheet, controlled drawing, quotation and approved sample. Capacitance and voltage alone are not sufficient for release.
