• High Rated Voltage — 350 V rated voltage suitable for high-voltage applications requiring electrolytic bulk capacitance.
• Snap-In Radial Can Package — Snap-in terminal type and radial can package simplify installation in power assemblies and support automated handling (tray packing for mass production).
• Operating Temperature — Specified for −25 °C to 85 °C operation (rating applicable to the 350 V product range).
• Endurance — Qualified to withstand 3,000 hours of rated ripple current at 85 °C with defined limits for capacitance change, tan δ and leakage current after test.
• Ripple Current Performance — Rated ripple current of 2.55 A at 120 Hz and 3.647 A at 50 kHz, supporting sustained AC stress at the specified frequencies.
• Leakage Current Specification — Leakage current meets I ≤ 3√CV (µA) after 5 minutes’ application of rated voltage at 20 °C (C: µF, V: V).
• Electrical Loss (tan δ) — Maximum tan δ specified at 0.15 for the 350 V rating (measurement at 120 Hz, 20 °C).
• RoHS Compliant — Conforms to RoHS directive requirements.
• Physical Dimensions — Body dimensions approximately L: 5.0 cm × D: 2.5 cm; height seated maximum 1.969 inches; nominal sleeve marking in white on black.

Typical Applications

• General-purpose electronic assemblies — Provides high-voltage bulk capacitance where a 470 µF, 350 V electrolytic capacitor is required in power modules and assemblies.
• High-voltage bulk storage — Used in circuits that require stored energy at higher DC voltage levels within the specified temperature and endurance limits.
• Production-ready power components — Tray packing and snap-in mounting support automated placement and assembly for mass production runs.

Unique Advantages

• High-voltage capability: 350 V rating delivers substantial DC voltage headroom for high-voltage capacitor requirements.
