UPH2G221MHD

The UPH2G221MHD is a 220 µF, 400 V polarized aluminum electrolytic capacitor from Nichicon's UPH series. It is a miniature, radial-lead can designed for high-voltage DC filtering and energy-storage duties in compact power-electronic circuits.

Engineered for applications that require high ripple handling and extended life at elevated temperatures, this part delivers a combination of high ripple current capability, long load life (2000 hours at 105°C), and RoHS compliance.

Key Features

• Capacitance & Voltage — 220 µF capacitance rated at 400 V for high-voltage DC smoothing and energy storage.
• High ripple-current capability — Rated ripple current of 1.2 A at 120 Hz and 1.8 A at 10 kHz to support demanding AC ripple conditions.
• Extended high-temperature life — Load life specified at 2000 hours at 105°C, enabling sustained operation in hot environments.
• Wide operating temperature range — Specified for –40°C to +105°C operation for compatibility with industrial thermal requirements.
• Compact radial-can package — Radial lead, can-style package with dimensions L: 4.6 × D: 1.8 cm and a lead spacing of 7.5 mm for space-conscious designs.
• Polarized, radial-lead mounting — Standard radial lead configuration for through-hole assembly and robust mechanical retention.
• RoHS compliant — Compliant with RoHS directives (2011/65/EU, (EU)2015/863) for regulated material content.
• Identification marking — Printed with white letters on a dark brown sleeve for clear part identification on the assembly.

Typical Applications

• Ballast and lighting power supplies — Provides high-voltage smoothing and ripple handling for electronic ballasts and auxiliary lighting electronics.
• Industrial power supplies — Serves as a compact DC filter and energy reservoir in high-voltage industrial converters and supplies.
• High-voltage DC circuits — Useful where 400 V rated capacitance and high ripple capability are required in a small footprint.
• General-purpose electronics — Appropriate for designs needing long-life electrolytic capacitance in elevated-temperature environments.

Unique Advantages

• High-voltage capability: 400 V rating enables use in higher-voltage DC rails without additional series components.
• High ripple performance: Specified ripple currents (1.2 A at 120 Hz, 1.8 A at 10 kHz) reduce heating and extend service life in ripple-heavy applications.
• Long elevated-temperature life: 2000 hours at 105°C provides predictable endurance for designs exposed to sustained thermal stress.
• Compact form factor: Small radial-can footprint (L: 4.6 × D: 1.8 cm) and 7.5 mm lead spacing help minimize board area in through-hole designs.
• Regulatory compliance: RoHS compliance supports deployment in regions and product lines that require restricted substance adherence.
• Clear part identification: White printing on a dark brown sleeve simplifies assembly verification and inventory management.
