Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 200 V rated voltage, suitable for high-voltage bulk capacitance requirements.
• Frequency and Ripple Performance — Low-frequency ripple current of 700 mA at 120 Hz and high-frequency ripple current of 1.12 A at 10 kHz to support filtering across a range of operating frequencies.
• Dissipation and Loss — Tangent of loss angle (tan δ) of 0.2 measured at 20 °C, 120 Hz, providing a defined dissipation characteristic for thermal and ripple calculations.
• Leakage Current — Specified leakage current of 1860 µA, enabling predictable standby and bias behavior after rated voltage application.
• Reliability & Endurance — Rated for 2000 hours at 85 °C with capacitance change within ±20% and tan δ within specified limits after the endurance test.
• Mechanical & Mounting — Radial lead package with 7.5 mm lead spacing (±0.5 mm tolerance) and a compact size of φ16 × 35.5 mm to fit space-constrained PCB layouts.
• Polarized, General-Purpose Design — Polarized aluminum electrolytic intended for general-purpose electronic applications.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible assembly and procurement.
• RoHS Compliant — Manufactured to meet RoHS requirements for restricted substances.

Typical Applications

• Power Supply Filtering — Bulk smoothing and decoupling on 200 V rails where 220 µF capacitance and defined ripple current capability are required.
• Industrial Electronics — General-purpose energy buffering and filtering in equipment operating within –40 °C to 85 °C and requiring 2000-hour endurance at elevated temperature.
• High-Voltage DC Circuits — Support for decoupling and transient suppression in higher-voltage DC circuits up to the 200 V rating.

Unique Advantages

• 200 V Rating for Higher-Voltage Designs: Enables use in 200 V systems without stacked or series arrangements, simplifying design.
• Compact φ16 × 35.5 mm Footprint: Miniature can-style package offers high capacitance in a small radial-lead form factor for tighter board layouts.
• Defined Ripple Handling: Separate low-frequency and high-frequency ripple current specs (700 mA at 120 Hz and 1.12 A at 10 kHz) allow precise thermal and performance planning.
• Long Endurance at Elevated Temperature: 2000 hours at 85 °C provides predictable aging characteristics for product lifetime planning.
• RoHS Compliance: Meets environmental requirements for restricted substances, simplifying regulatory adherence.
