UPTW6220MHD

The UPTW6220MHD is a 22 µF, 420 V aluminum electrolytic capacitor in a compact radial can package designed for general-purpose power applications where high ripple current and long operational life are required. It combines a high-voltage rating and polarized radial-lead construction with a small footprint (L: 2.5 × D: 1.25 cm) and 5 mm lead spacing for straightforward through-hole mounting.

Engineered for elevated-temperature endurance, this Nichicon UPT series part delivers long life at high operating temperature and RoHS-compliant construction for modern designs.

Key Features

• High Voltage Rating — Rated for 420 V, suitable for circuits requiring elevated DC working voltage.
• Compact Radial Can Package — Small dimensions (L: 2.5 × D: 1.25 cm) with 5 mm lead spacing and radial lead mounting for easy through-hole assembly.
• High Ripple Current Handling — Rated ripple current 200 mA at 120 Hz and 320 mA at 10 kHz, supporting designs with significant AC ripple on the DC bus.
• Long Life at Elevated Temperature — Endurance specified as 5000 hours at 105°C when subjected to rated DC bias plus rated ripple current.
• Wide Operating Temperature Range — Specified for −40°C to +105°C operation, supporting a broad set of thermal environments.
• Electrical Stability — Capacitance tolerance ±20% (120 Hz, 20°C) and specified tan δ (max. 0.20 at 420 V, 120 Hz, 20°C), with leakage current defined by the datasheet formula (≤ 0.06CV + 10 µA after 2 minutes at 20°C).
• Regulatory Compliance — RoHS compliant for use in modern lead-restricted assemblies.

Typical Applications

• Ballasts — High ripple current capability makes this part well-suited for ballast circuits where sustained ripple and elevated voltage are encountered.
• General-purpose Power Electronics — Useful for DC bus filtering and smoothing in power supplies and electronic modules that require a compact, high-voltage polarized capacitor.
• Industrial Power Systems — Designed for applications that need reliable long-life capacitors at elevated temperatures and continuous ripple exposure.

Unique Advantages

• Compact footprint with high-voltage capability: 22 µF at 420 V in a small radial can reduces board area without sacrificing voltage rating.
• Designed for ripple-loaded environments: Rated ripple currents at both 120 Hz and 10 kHz (200 mA / 320 mA) address AC stress across a range of frequencies.
• Proven endurance at temperature: 5000-hour life at 105°C under rated bias and ripple supports designs targeting longevity in harsh thermal conditions.
• Predictable electrical behavior: Specified tan δ and leakage current formula provide verifiable parameters for design validation and reliability calculations.
• Through-hole ease-of-use: Radial lead construction with standard 5 mm lead spacing simplifies assembly and replacement in legacy and new designs.
• RoHS compliance: Meets lead-restriction requirements for modern manufacturing and environmental standards.
