Verification note: Values stated by the attached applicable LORIDA series file take priority over older website text. Confirmed title ratings are retained. When the exact series, case option, ripple value, lifetime, or compliance record is not identified, the controlled datasheet, drawing, quotation, and approved sample govern.

Product Information

Radial construction built around electrical and mechanical fit

This page is a selection starting point for polarized radial aluminum electrolytic capacitors. Approval must combine the electrical rating with case diameter, height, lead spacing, polarity, temperature, ripple duty and required service life.

Confirmed on this page

Radial through-hole construction and the product-family information shown in the specification table.

Still series-dependent

Case size, lead pitch, tolerance, ripple current, ESR or impedance, leakage, temperature range and endurance.

Send for review

Original part or datasheet, circuit position, mechanical envelope, life target, quantity and compliance needs.

Radial selection priorities

Electrical match

Confirm rated voltage, surge conditions, capacitance tolerance, ripple waveform and frequency-dependent ESR or impedance.

PCB fit

Lock case diameter × height, lead spacing, lead diameter, polarity marking and available board clearance against the controlled drawing.

Thermal and life target

State ambient temperature, self-heating, duty cycle and expected service life. Do not approve lifetime from a nominal temperature rating alone.

Replacement projects

Provide the original datasheet and clear product photos. Electrical similarity does not guarantee mechanical or endurance equivalence.

Typical evaluation points

Auxiliary power

Review voltage margin, ripple, board temperature and start-up conditions.

Filtering and smoothing

Check ripple current, frequency, impedance and heat rise in the real circuit.

Control electronics

Confirm leakage, tolerance, lifetime and available PCB space.

Maintenance replacement

Match polarity, footprint, height and all critical electrical limits.

Qualification path for repeat supply

Requirement review: align the circuit, ratings, environment and mechanical limits.
Series matching: compare controlled series data and available case options.
Sample approval: record the approved part, drawing and test criteria.
Order control: keep marking, packing, inspection and change-control requirements aligned.

Ordering information

A complete RFQ lets engineering and sales review the same requirement set without repeated clarification. Include the original part or datasheet for replacement work.

Application
Circuit position and operating function

Electrical limits
Capacitance, voltage, surge, ripple and frequency

Mechanical envelope
Diameter, height, lead spacing and clearance

Environment
Temperature, duty cycle and expected life

Qualification
Samples, drawings, inspection and compliance needs

Commercial program
Sample, order and annual quantities plus packing needs

Documents and release basis

Request the current controlled datasheet, outline drawing, applicable inspection information, packing reference and order-specific compliance records for the selected series.

Final approval basis: controlled datasheet, controlled drawing, quotation and approved sample. Values shown on an older web page do not override the current controlled series file.

Frequently asked questions

Can two radial capacitors with the same capacitance and voltage be interchanged?

No. Case size, lead spacing, tolerance, ripple current, ESR or impedance, leakage, temperature range and endurance must also be checked.

What should I send for a cross-reference?

Send the original datasheet or part number, product photos, circuit position, mechanical limits, operating temperature, ripple conditions and required lifetime.

Can samples be reviewed before a volume order?

Yes. Sample approval should record the selected series, dimensions, marking and agreed qualification criteria before repeat supply.

Can this page approve use in safety-critical equipment?

No. Automotive, medical, safety-critical and regulated applications require application-specific engineering review and the applicable controlled documentation.
