Key Features

• Capacitance & Tolerance — 120 µF nominal capacitance with a tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• High Rated Voltage — Rated for 450 V to support high-voltage circuit requirements.
• Low Loss (tan δ) — tan δ (DF) of 0.20 measured at 20°C and 120 Hz, providing predictable AC loss performance.
• Ripple Current Specs — Low-frequency ripple current of 810 mA at 120 Hz and high-frequency ripple current of 1.296 A at 10 kHz, with frequency coefficients provided for other frequencies.
• Leakage Current — Specified leakage current of 2260 µA at the stated measurement condition.
• Long Endurance — Rated life of 5000 hours at 105°C with defined limits for capacitance change, tan δ increase, and leakage current after the endurance test.
• Operating Temperature Range — Specified for -40°C to +105°C operation.
• Compact Radial Package — φ16 × 36 mm can with 7.5 mm lead spacing (±0.5 mm); radial lead mounting for through-hole assemblies. Available in bulk or bag packing.

Typical Applications

• General-purpose electronic equipment — Suited for general-purpose assemblies where a compact, high-voltage electrolytic capacitor is required.
• High-voltage circuit modules — Applicable where 450 V rating is needed in a miniature radial-lead form factor.
• Long-life, elevated-temperature environments — Designed for applications requiring defined endurance at up to 105°C for extended periods.

Unique Advantages

• High-voltage capability: 450 V rating enables use in circuits requiring substantial DC voltage handling.
• Defined long-term reliability: 5000 h endurance at 105°C with specified post-test limits for capacitance, tan δ and leakage current supports predictable lifespan planning.
