Key Features

• Capacitance & Voltage — 220 µF capacitance at a rated voltage of 16 V with ±20% tolerance, suitable for bulk filtering and energy storage in low-voltage power rails.
• Low Loss (tan δ) — Specified tan δ of 0.15 for controlled dissipation and stable performance under AC conditions.
• Ripple Current Handling — Rated ripple current of 500 mA at 120 Hz and 800 mA at 10 kHz, enabling use in both low- and high-frequency switching environments.
• Endurance & Temperature — 8000 hours life at 105°C with an operating temperature range of -40°C to 105°C for extended reliability in elevated-temperature applications.
• Mechanical & Mounting — Radial lead, can-style package with dimensions φ20 × 31 mm and lead spacing of 10 mm for through-hole assemblies.
• Leakage Current — Specified leakage current of 1508 µA after rated voltage application at 20°C (as provided).
• Automotive-Grade Reliability — AEC‑Q200 rated for applications requiring industry-recognized component stress screening.
• Packaging — Supplied in bulk (no terminal forming) / bag packing for high-volume assembly or inventory storage.

Typical Applications

• Switching Power Supplies — Bulk and decoupling capacitor for compact, low-voltage switching regulators where low impedance and ripple handling are required.
• Automotive Electronic Systems — Energy storage and filtering in automotive modules that require AEC‑Q200 qualified passive components.
• Power Filtering in Compact Assemblies — Space-conscious through-hole designs that need robust ripple tolerance and extended high-temperature endurance.

Unique Advantages

• Compact, high-capacitance radial can — φ20 × 31 mm package delivers 220 µF in a small footprint for space-limited board layouts.
• High-frequency ripple capability — 800 mA rating at 10 kHz supports switching-regulator environments and high-frequency decoupling.
• Long endurance at elevated temperature — 8000 hours at 105°C provides predictable lifetime behavior for sustained thermal stress.
• AEC‑Q200 qualification — Conforms to automotive stress-screening expectations for designs targeting vehicular applications.
• Low dissipation (tan δ = 0.15) — Reduced loss contributes to stable AC performance and thermal behavior in filtering roles.
• Radial lead format and standard lead spacing — 10 mm lead spacing and through-hole mounting simplify assembly and mechanical retention in rugged installations.
