UPT2W220MHD

The Nichicon UPT2W220MHD is a 22 µF, 450 V aluminum electrolytic capacitor in the UPT series. It is a miniature, radial-leaded can-style capacitor designed for general-purpose electronic assemblies and is explicitly noted as suited for ballast applications.

Engineered for high ripple environments and extended operation, UPT2W220MHD delivers specified high ripple current, long endurance at elevated temperature, and RoHS compliance for regulated designs.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance (120 Hz, 20°C).
• High Ripple Current — Rated ripple current of 220 mA at 120 Hz and 352 mA at 10 kHz; frequency coefficient increases to 1.60 at 10 kHz or more as specified in the datasheet.
• Long Life / Endurance — Specified lifetime of 5000 hours at 105°C with DC bias plus rated ripple; endurance criteria include capacitance change within ±20%, tan δ up to 200% of initial specified value, and leakage current less than or equal to the initial specification after test.
• Temperature Range — Operating temperature range from −40°C to +105°C.
• Package & Mounting — Radial lead, can-style package with 5.0 mm lead spacing and compact dimensions L: 3.05 × D: 1.25 cm for space-constrained board layouts.
• Dielectric/Leakage Performance — Leakage current specified as not more than 0.06CV + 10 μA after 2 minutes’ application of rated voltage at 20°C; tangent of loss angle (tan δ) maximum 0.20 for the 450 V rating (measured at 120 Hz, 20°C).
• Environmental Compliance — RoHS compliant.

Typical Applications

• Ballast circuits — Suited for ballast application where high ripple handling and long life at elevated temperature are required.
• General-purpose power circuitry — Designed for general-purpose electronics requiring a compact, high-voltage electrolytic capacitor.
• High-voltage power circuits — 450 V rating makes it applicable to higher-voltage filtering and smoothing tasks within its electrical limits.

Unique Advantages

• High ripple capability: Explicit rated ripple currents at 120 Hz and 10 kHz support designs with significant AC ripple components.
• Proven endurance: 5000 hours at 105°C under rated conditions provides a quantified life expectation for thermal and electrical stress.
• Compact radial package: Small footprint (L: 3.05 × D: 1.25 cm) and 5.0 mm lead spacing ease integration into densely packed PCBs.
• Measurable electrical stability: Leakage current and tan δ specified with clear test conditions (20°C, 120 Hz), enabling predictable electrical performance.
• Regulatory compliance: RoHS compliance supports use in regulated product lines.
