UPS2V221MRD

The UPS2V221MRD is a miniature, low‑impedance aluminum electrolytic capacitor designed for switching power supplies and general‑purpose power filtering. It is a radial‑lead, polarized component intended for through‑hole mounting where compact high‑voltage smoothing and ripple handling are required.

Key value comes from its high 350 V rating, compact 5.0 × 2.5 cm package, and a wide operating temperature range, making it suitable for demanding power‑electronics environments that require robust ripple performance and long life at elevated temperatures.

Key Features

• Capacitance & Voltage — 220 µF capacitance rated at 350 V to support high‑voltage DC filtering and energy storage in power supply rails.
• Low Impedance / Ripple Capability — Specified ripple current of 550 mA at 120 Hz and 880 mA at 10 kHz, supporting effective smoothing in switching regulator and converter applications.
• Wide Temperature Range — Operating temperature from −40 °C to 105 °C for reliable performance across typical industrial thermal environments.
• Long Endurance at High Temperature — Rated lifetime of 3000 hours at 105 °C, enabling extended service life under sustained elevated temperature and bias conditions.
• Compact Radial Can — Radial lead, can‑style package with lead spacing of 1.25 cm, overall dimensions L: 5 × D: 2.5 cm and a seated height of 1.969 inch for space‑constrained PCB layouts.
• Polarized, General‑Purpose Design — Polarized aluminum electrolytic construction with ±20% capacitance tolerance, suitable for DC link, smoothing, and bulk decoupling roles.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863), meeting regulatory requirements for lead‑free assemblies.

Typical Applications

• Switching Power Supplies — Bulk smoothing and DC link filtering to reduce ripple and stabilize output rails in switching regulators and power converters.
• Industrial Power Electronics — High‑voltage smoothing and energy buffering in industrial converters and power modules where elevated operating temperatures are encountered.
• General‑Purpose Power Filtering — Decoupling and bulk capacitance for high‑voltage DC circuits and control electronics that require compact through‑hole components.

Unique Advantages

• High Voltage Capacity: 350 V rating enables use in higher‑voltage DC rails without need for series stacking, simplifying design.
• Compact Footprint: Small 5.0 × 2.5 cm can and radial lead format reduce PCB area while retaining substantial capacitance for smoothing tasks.
• Designed for Ripple Performance: Specified ripple currents at both low and high frequencies support stable operation in fast switching environments.
• Durability at Elevated Temperature: 3000 h life at 105 °C provides predictable longevity for sustained high‑temperature applications.
• Regulatory Compliance: RoHS conformity simplifies integration into lead‑free assemblies and commercial products.
