UPS2F221MRD

The UPS2F221MRD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPS series, designed for compact, low-impedance power applications. It provides 220 µF capacitance at a 315 V rating and is optimized for general-purpose power filtering and decoupling in switching power supplies and power conversion circuits.

With a wide operating temperature range and a 3,000‑hour endurance at 105 °C, this capacitor balances voltage capability, ripple handling and long-term reliability in a φ22×50 mm radial can package with 10 mm lead spacing.

Key Features

• Radial lead can package — φ22×50 mm size with 10 mm lead spacing for through-hole mounting and straightforward PCB layout.
• 315 V rated voltage — Suitable for higher DC bus and power conversion applications requiring elevated voltage capability.
• 220 µF capacitance with ±20% tolerance — Provides bulk energy storage and smoothing for power rails and intermediate DC links.
• Low dissipation factor — tanδ of 0.09 measured at 20 °C, 120 Hz, indicating relatively low dielectric losses for improved ripple performance.
• Ripple current capability — Rated low-frequency ripple current of 540 mA at 120 Hz and high-frequency ripple current of 864 mA at 10 kHz to address both mains-frequency and switching-frequency ripple.
• Leakage and endurance — Leakage current specified at 2,872 µA and designed for 3,000 hours of endurance at 105 °C under rated conditions.
• Wide operating temperature — Specified for −40 °C to +105 °C to cover many industrial and commercial environments.
• RoHS compliant — Meets RoHS environmental requirements for lead-free manufacturing.
• Packaging options — Available in bulk (no terminal forming) and bag packing to suit prototyping and production needs.

Typical Applications

• Switching power supplies — Bulk filtering and decoupling on DC bus and output rails to reduce ripple and stabilize voltage under load.
• DC‑DC converters — Energy storage and smoothing in intermediate stages where elevated voltage capability (315 V) is required.
• Industrial power electronics — General-purpose filtering and transient buffering in commercial and industrial power systems operating up to 105 °C.
• Power conversion modules — Supporting both low-frequency and high-frequency ripple conditioning thanks to specified ripple current ratings at 120 Hz and 10 kHz.

Unique Advantages

• High voltage capability: 315 V rating enables use on higher-voltage DC buses and power conversion stages without series stacking.
• Balanced ripple performance: Distinct ripple current ratings for 120 Hz and 10 kHz provide measurable guidance for both mains and switching-frequency applications.
• Thermal endurance: 3,000‑hour rating at 105 °C offers predictable long-term performance in elevated-temperature installations.
• Compact radial form factor: φ22×50 mm can-style package delivers substantial capacitance in a footprint suitable for through-hole designs.
• Measurable loss characteristics: Specified tanδ at 20 °C, 120 Hz (0.09) helps engineers estimate dielectric losses and thermal behavior under operating conditions.
• RoHS compliant: Supports lead‑free manufacturing and environmental compliance requirements.
