• Electrical Losses — Tangent of loss angle (tan δ) of 0.07 (specified value at 120 Hz, 20°C for this part).
• Leakage and Endurance — Leakage current 207 µA (after 2 minutes at 25°C) and endurance rated for 2000 hours at 105°C under rated voltage test conditions.
• Mechanical & Packaging — Compact φ8 × 11.5 mm can, lead spacing 3.5 mm (±0.5 mm), supplied bulk (no terminal forming) or bag-packed for production handling.
• Operating Temperature — Wide operating range from −55°C to +105°C.

Typical Applications

• General-purpose electronics — Intended for general-purpose applications requiring a 220 µF, 6.3 V conductive polymer aluminum capacitor in a radial-lead format.
• Bulk/bag-packed assembly workflows — Available in bulk (no terminal forming) and bag packing to support various board assembly and handling processes.
• Thermally stressed environments within spec — Rated for operation from −55°C to +105°C with specified 2000-hour endurance at 105°C for designs that require documented lifetime at elevated temperature.

Unique Advantages

• Low AC impedance: 21 mΩ ESR at 100 kHz lowers impedance at high frequency, supporting applications that reference the part’s high-frequency performance metrics.
• High ripple capability: Specified ripple current values of 390 mA (120 Hz) and 3.9 A (300 kHz) address both low- and high-frequency ripple requirements as listed in the part data.
• Thermal endurance: Endurance rating of 2000 hours at 105°C under rated voltage provides a defined lifetime for thermal stress planning.
• Stable electrical characteristics: Specified tan δ of 0.07 and leakage current of 207 µA give clear, verifiable loss and leakage behavior for design margin calculations.
• Compact radial package: φ8×11.5 mm can with 3.5 mm lead spacing supports space-constrained board-level implementations while preserving standard radial-lead handling.
• Production readiness: Mass production status and standard packaging options simplify procurement and onboarding into production BOMs.
