Product Information

Built around board-level selection and assembly

This 820µF / 6.3V SMD aluminum electrolytic capacitor is a board-level selection starting point for compact filtering and local energy support. Final approval must align electrical stress, thermal rise, footprint, polarity, reflow exposure and the required service life.

Electrical review

Confirm working voltage, surge, ripple current by frequency, ESR or impedance, leakage and transient duty.

Thermal review

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

PCB and assembly review

Match case diameter and height, land pattern, polarity, placement clearance, reel format and reflow profile.

Why the SMD format changes the selection process

Surface-mount aluminum electrolytic capacitors support automated placement and compact power filtering, but the same capacitance and voltage do not guarantee interchangeability. Case code, terminal geometry, polarity marking, ripple heating, impedance behavior, permitted reflow conditions and endurance must be reviewed together.

Power rails and converters

Review ripple spectrum, switching conditions, load steps, board temperature and available cooling.

OEM and EMS assembly

Control land pattern, polarity orientation, placement height, reflow exposure, reel packing and lot traceability.

Replacement and distribution

Cross-reference the original datasheet and physical package; never approve a substitute from the headline rating alone.

Qualification workflow

Define circuit stress: working voltage, surge, ripple waveform, frequency and transient conditions.
Lock the footprint: case dimensions, land pattern, polarity, height and nearby-component clearance.
Align assembly: placement method, reel orientation, reflow profile, handling and cleaning conditions.
Review thermal life: ambient, board temperature, self-heating, duty cycle and service-life target.
Approve samples: electrical behavior, fit, soldering, polarity, temperature rise and inspection criteria.
Control repeat supply: selected series, drawing, marking, packing, inspection and change requirements.

Ordering information

Send the complete application requirement so engineering and sales can review the same specification without repeated clarification.

Documents and approval basis

Request the current controlled datasheet, package drawing, recommended land pattern, reflow guidance, packing reference and order-specific compliance records for the selected series.

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