• Long Life & Wide Temperature Range — Rated for 10000 hours at 105 °C and specified operating range from −40 °C to 105 °C for extended reliability in elevated-temperature environments.
• Package & Mounting — Compact radial can, size φ16 × 15 mm with lead spacing 7.5 mm (±0.5 mm), mounting via radial leads for through-hole assemblies.
• Packaging Options & Production Status — Available in bulk (no terminal forming) and bag packing; status: mass production. RoHS compliant.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple reduction on DC power rails where 63 V rating and 270 µF capacitance are required.
• Decoupling for power converters — Supports switching supplies and DC–DC converters with high ripple current handling and low impedance characteristics.
• General-purpose electronic equipment — Suitable for consumer, industrial and instrumentation circuits requiring compact, long-life electrolytic capacitance.

Unique Advantages

• Extended endurance at elevated temperature — 10000 hour rating at 105 °C helps ensure longevity in designs exposed to high operating temperatures.
• Broad ripple-frequency capability — Specified ripple current values for both low and high frequencies enable reliable performance across switching and line-frequency environments.
• Compact radial form factor — φ16 × 15 mm can and 7.5 mm lead spacing offer a space-efficient through-hole solution for power and filter stages.
• Predictable dissipation and leakage — Measured tan δ and leakage current figures support accurate thermal and loss budgeting in designs.
• Production-ready supply — Mass production status and standard packaging options (bulk/bag) simplify procurement and assembly planning.
