UPS2A221MHD

The UPS2A221MHD is a miniature, low‑impedance aluminum electrolytic capacitor designed for switching power supplies and general‑purpose power applications. It provides 220 µF capacitance at a 100 V rating in a compact radial‑lead can, offering a balance of ripple handling, temperature range and long‑term endurance for power smoothing and decoupling tasks.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance with a 100 V rated voltage and tolerance of ±20%.
• Low Impedance — Specified impedance of 100 mΩ to support low‑loss power filtering and decoupling.
• Ripple Current Performance — Rated ripple current of 445 mA at 120 Hz and 890 mA at 10 kHz, enabling effective AC ripple handling across frequency ranges.
• Wide Temperature Range — Operates from −55°C to +105°C to accommodate demanding thermal environments.
• High‑Temperature Endurance — Rated for 3000 hours at 105°C under specified DC bias plus rated ripple current for long service life in hot operating conditions.
• Compact Radial Can Package — Radial lead, can‑type construction with lead spacing of 7.5 mm and dimensions L: 2.5 cm × D: 1.6 cm for space‑constrained designs.
• Polarized, General‑Purpose Use — Polarized aluminum electrolytic suitable for general power supply filtering and decoupling roles.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• Switching Power Supplies — Bulk smoothing and output decoupling where miniature, low‑impedance capacitors are required.
• DC‑DC Converters — Input and output filtering to reduce ripple and stabilize voltage rails in power modules.
• Industrial Power Electronics — General‑purpose power filtering in equipment that operates across a wide temperature range.
• Consumer and Embedded Devices — Space‑efficient energy storage and decoupling on compact power boards.

Unique Advantages

• High Voltage Handling: 100 V rating enables use on higher‑voltage rails without upsizing the capacitor.
• Effective Ripple Management: Specified ripple currents at 120 Hz and 10 kHz support filtering across low and high frequencies.
• Compact Footprint: Small radial can (L: 2.5 cm × D: 1.6 cm) with 7.5 mm lead spacing helps minimize board area in dense designs.
• Wide Thermal Range and Long Life: −55°C to +105°C operation and 3000‑hour endurance at 105°C provide predictable performance in elevated temperatures.
• Low Impedance: 100 mΩ impedance contributes to lower voltage ripple and improved power integrity.
• Regulatory Compliance: RoHS compliance simplifies material and regulatory tracking for product development.
