UPHW6330MPD

The UPHW6330MPD is a radial‑lead, miniature aluminum electrolytic capacitor from Nichicon’s UPH series, rated for 420 V and 33 µF. Designed for high‑voltage, compact applications, it delivers sustained performance with a 2000‑hour life at 105°C and RoHS compliance.

Its compact φ10 × 31.5 mm can and radial lead form factor make it suitable for general‑purpose high‑voltage filtering and ballast applications where high ripple capability and long endurance are required.

Key Features

• High Voltage Rating — Rated voltage 420 V to support high‑voltage DC circuits and ballast applications.
• 33 µF Capacitance — Nominal capacitance of 33 µF with tolerance of −20% to +20% for predictable filtering performance.
• High Ripple Current Capability — Low‑frequency ripple current 320 mA (120 Hz) and high‑frequency ripple current 480 mA (10 kHz) to handle varying ripple conditions.
• Endurance at Elevated Temperature — Specified load life of 2000 hours at 105°C with defined limits for capacitance change, tan δ, and leakage current after test.
• Electrical Loss Characteristic — tan δ (DF) 0.20 measured at 20°C, 120 Hz, for predictable dissipation behavior.
• Compact Radial Package — Case size φ10 × 31.5 mm with 5.0 mm lead spacing (±0.5 mm), radial lead mounting for through‑hole PCBs.
• Leakage Current — Specified leakage current 654.4 µA for design validation and safety margin planning.
• Compliance & Availability — RoHS‑compliant and available in mass production with bulk/bag packing options.

Typical Applications

• Lighting Ballasts — Supports AC/DC and electronic ballast designs with high‑voltage rating and long endurance at 105°C.
• Power Supply Filtering — Provides high‑voltage smoothing and ripple suppression in compact power supplies and DC link circuits.
• General‑Purpose High‑Voltage Circuits — Suited to space‑constrained, high‑voltage applications requiring reliable electrolytic capacitance.

Unique Advantages

• High‑voltage in a miniature footprint: 420 V rating combined with a φ10 × 31.5 mm case supports compact board layouts without sacrificing voltage capability.
• Designed for continuous high‑temperature operation: 2000‑hour endurance at 105°C reduces replacement frequency in thermally demanding environments.
• Broad ripple handling: Specified ripple currents at both low and high frequencies accommodate a range of switching and mains‑frequency conditions.
• Predictable loss and leakage: Defined tan δ and leakage current values aid thermal and leakage budgeting during design.
• Radial lead form factor: Through‑hole mounting and 5.0 mm lead spacing streamline assembly for PCB designs using radial components.
• Production readiness: RoHS‑compliant and in mass production with bulk/bag packing for volume procurement and assembly.
