Key Features

• Electrical Rating — 220 µF capacitance with a rated voltage of 450 V and capacitance tolerance of ±20% (−20% to +20%).
• Polarized Radial Lead Package — Radial lead mounting with φ25 × 50 mm can dimensions and 12.5 mm lead spacing (±0.5 mm tolerance) for straightforward through-hole PCB integration.
• Temperature and Endurance — Operating temperature range from −25°C to +105°C with an endurance rating of 2000 hours at 105°C under rated voltage.
• Ripple and Leakage Characteristics — Low-frequency ripple current of 250 mA (120 Hz), high-frequency ripple current of 400 mA (10 kHz), and measured leakage current of 4060 µA as specified for this part.
• Loss Factor — Tangent of loss angle (tan δ) specified at 0.25 (measured at 20°C, 120 Hz) to indicate dissipation characteristics.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to support prototyping and volume builds.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-purpose electronic circuits — Specified for general-purpose use where a polarized 220 µF, 450 V electrolytic capacitor is required.
• Through-hole PCB assemblies — Radial lead format and 12.5 mm lead spacing facilitate placement in through-hole designs and repairs.
• Production and prototyping — Bulk and bag packing options support small-batch prototyping and larger production runs.

Unique Advantages

• High-voltage capability: 450 V rating enables use in circuits that require elevated DC voltage handling.
• Robust thermal endurance: Rated for 2000 hours at 105°C, providing predictable performance in higher-temperature operating conditions.
• Compact can size for value: 220 µF provided in a φ25 × 50 mm can offers a balance of capacitance and footprint for radial aluminum electrolytic designs.
• Measurable ripple handling: Specified ripple currents (250 mA at 120 Hz, 400 mA at 10 kHz) let designers size capacitors against expected AC ripple across frequencies.
• Clear electrical specifications: Defined tan δ (0.25 at 20°C, 120 Hz) and documented leakage current help with thermal and leakage budgeting in designs.
• RoHS compliant: Environmentally compliant construction for global design requirements.
