UPS1H221MPD

The UPS1H221MPD is a miniature, low-impedance aluminum electrolytic capacitor in a radial-can package designed for switching power supplies and general-purpose power filtering. It combines compact dimensions and robust electrical performance to support dense board layouts and power-regulation circuits.

Key characteristics include a 220 µF capacitance at 50 V rating, wide operating temperature range from −55°C to 105°C, and RoHS compliance, delivering reliable performance across a broad set of embedded and industrial applications.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance rated at 50 V with ±20% tolerance for bulk energy storage and decoupling.
• Low Impedance Performance — Specified impedance of 180 mΩ to support low-loss filtering in switching power supplies and power rails.
• Ripple Current Handling — Rated ripple currents of 325 mA at 120 Hz and 650 mA at 10 kHz to accommodate switching ripple in modern converters.
• Wide Temperature Range & Durability — Operates from −55°C to 105°C with a rated lifetime of 2000 hours at 105°C, suitable for sustained elevated-temperature operation.
• Compact Radial-Lead Can — Miniature package with dimensions L: 1.6 cm × D: 1.0 cm, 5 mm lead spacing, and radial lead mounting for through-hole assembly in space-constrained designs.
• Polarized Design — Standard polarized aluminum electrolytic construction for bulk storage and smoothing applications.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863) for regulatory compliance in many markets.

Typical Applications

• Switching Power Supplies — Bulk and output smoothing where low impedance and defined ripple handling improve converter stability and transient response.
• Embedded Power Rails — Local energy storage and decoupling on compact PCBs for routers, controllers, and embedded processors.
• Industrial Power Modules — Filtering and energy buffering in compact power assemblies operating across a wide temperature range.
• Consumer Electronics Power Sections — Space-efficient decoupling and smoothing in adapters, chargers, and powered peripherals.

Unique Advantages

• Space-saving form factor: Miniature L: 1.6 cm × D: 1.0 cm package reduces board area for designs with tight component density.
• Low-impedance filtering: 180 mΩ impedance helps reduce voltage ripple and improves power-supply performance in switching applications.
• High ripple capability: Specified ripple currents at both 120 Hz and 10 kHz accommodate a range of switching frequencies and load conditions.
• Wide operating temperature: −55°C to 105°C rating and 2000-hour life at 105°C support reliable operation in thermally demanding environments.
• Through-hole robustness: Radial-lead can package offers mechanical stability and straightforward assembly for repairable or serviceable products.
• Regulatory compliance: RoHS conformity simplifies material compliance for global product shipments.
