• Long Life Endurance — Rated for 5000 hours at 105 °C under D.C. bias plus rated ripple current, with capacitance change within ±20% after the endurance test.
• Wide Operating Temperature — Specified temperature range from −40 °C to +105 °C for reliable performance across temperature extremes.
• Low-Frequency & High-Frequency Ripple Handling — Low-frequency ripple current 920 mA at 120 Hz and high-frequency ripple current 1.472 A at 10 kHz, enabling effective smoothing across frequency ranges.
• Electrical Losses — Tangent of loss angle (tan δ) max 0.20 measured at 20 °C, 120 Hz, supporting predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 2788 µA, measured under the product’s defined conditions for initial quality assessment.
• Package & Mounting — Radial lead (can) package, case dimension φ18 × 36 mm with 7.5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing for flexible assembly processes.
• Polarized Design — Polar capacitor suitable for DC circuits where polarity is observed.

Typical Applications

• General-Purpose High-Voltage Circuits — Use where a compact 420 V, 160 µF radial electrolytic capacitor is required for energy storage and smoothing in high-voltage assemblies.
• Long-Life Power Modules — Suitable for designs that demand 5000 hours of endurance at elevated temperature (105 °C) and stable capacitance over time.
• Temperature-Stable Installations — Applicable in equipment that operates across −40 °C to +105 °C and requires capacitors with defined electrical loss (tan δ) at standard test conditions.

Unique Advantages

• High-Voltage Capability: 420 V rating enables deployment in higher-voltage DC circuits without sacrificing capacitance.
• Compact Miniature Case: φ18×36 mm size provides a space-efficient solution for designs constrained by board area or height.
