Product Information

Built around board-level selection and assembly

Electrical review

Check ripple current, ESR or impedance, leakage, surge and switching conditions.

Thermal review

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

PCB review

Confirm Ø6.3 × 8mm envelope, land pattern, height, polarity, clearance and reflow profile.

Why the SMD Format Matters

Compact automated assembly with clear footprint control

SMD aluminum electrolytic capacitors support automated PCB placement and compact power filtering. For this 680µF 6.3V option, nominal value and case size define the starting point, while ripple heating, impedance behavior, reflow exposure and operating life determine the final fit.

Best Fit for Buyers

Where this rating can enter a sourcing shortlist

OEM / EMS production

Use for high-capacitance compact DC-rail buffering when footprint, reflow, sample approval and repeatable packing must be controlled.

Distribution programs

Cross-reference capacitance, voltage, dimensions, temperature, endurance, polarity marking and reel requirements together.

Qualification Workflow

From circuit requirement to controlled supply

1. Define stress

Voltage, surge, ripple, frequency and temperature.

2. Confirm footprint

Diameter, height, land pattern, polarity and clearance.

3. Align reflow

Assembly process, peak exposure and handling conditions.

4. Review samples

Electrical behavior, fit, soldering and temperature rise.

5. Lock documents

Datasheet, drawing, inspection and packing references.

6. Repeat supply

Marking, reels, lot control and order requirements.

FAQ

Checks before sample approval

Is the same capacitance and voltage interchangeable?

No. Case size, footprint, polarity, ripple current, impedance, temperature and life also need review.

Can this part use automated placement?

The selected packing, land pattern and reflow conditions should be aligned with the assembly line.

Can marking and packaging be customized?

Customer-brand marking, labels, reels and cartons can be evaluated with the program requirements.

What should sample testing include?

Electrical behavior, fit, polarity, soldering quality, temperature rise and the agreed inspection criteria.
