UVR1H221MPD

The UVR1H221MPD is a miniature radial-lead aluminum electrolytic capacitor from Nichicon’s UVR series, designed for general-purpose and entertainment electronics. It provides 220 µF of capacitance at a 50 V rating in a compact φ10 × 12.5 mm can with 5 mm lead spacing.

Engineered for compact power-decoupling and smoothing duties, this polarized capacitor delivers measurable ripple handling and a defined endurance specification, making it suitable for designs that require a small footprint with reliable electrical performance in ambient temperatures from −40°C to 85°C. The device is RoHS compliant.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 50 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Low loss (tan δ) — Rated tanδ of 0.12 when measured at 20°C, 120 Hz and 50 V, supporting predictable AC behavior in filtering applications.
• Ripple current capability — Handles 430 mA at 120 Hz (low frequency) and 645 mA at 10 kHz (high frequency), enabling effective smoothing of power rails across frequencies.
• Leakage current — Specified leakage current of 330 µA after voltage application at 20°C, supporting stable long-term bias conditions.
• Endurance — Rated life of 2000 hours at 85°C with specified limits for capacitance change, tanδ, and leakage current after the endurance test.
• Package & mounting — Radial lead can (φ10 mm diameter × 12.5 mm length) with 5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing for manual assembly.
• Operating temperature — −40°C to 85°C for broad environmental compatibility within its specified category range.
• Regulatory — RoHS compliant.

Typical Applications

• Consumer & Entertainment Electronics — Bulk and decoupling capacitor for power supplies and analog stages in entertainment devices where the UVR series is specified.
• General-purpose power smoothing — Filtering and reservoir duties on DC rails up to 50 V, benefiting from specified ripple‑current ratings.
• Audio and signal circuits — Support for power decoupling in audio front-ends and control electronics, leveraging low loss (tanδ) characteristics.

Unique Advantages

• Compact footprint: φ10 × 12.5 mm can and 5 mm lead spacing deliver high capacitance in a small radial package to save board area.
• Defined ripple performance: Separate low- and high-frequency ripple current ratings (430 mA at 120 Hz, 645 mA at 10 kHz) provide clarity for multi-frequency power designs.
• Predictable loss characteristics: Specified tanδ (0.12 at 20°C, 120 Hz, 50 V) helps designers estimate AC dissipation in filtering applications.
• Long endurance at elevated temperature: 2000 hours at 85°C ensures consistent electrical parameters after extended operation under rated conditions.
• RoHS compliant: Meets restricted substance requirements for regulated markets.
• Multiple packing options: Bulk (no terminal forming) or bag packing supports flexible handling for manual or small-volume assembly workflows.
