UVK1H221MPD

The UVK1H221MPD is a miniature aluminum electrolytic capacitor in Nichicon’s UVK series, supplied in a radial-lead can package. It offers 220 µF nominal capacitance at a 50 V rating with polarized construction for general-purpose electronic designs.

Designed for space-constrained assemblies, the part combines a compact φ10 × 12.5 mm can with radial leads and is rated for operation from −40℃ to 85℃ with a 2000 hour endurance at 85℃, making it suitable for a wide range of general-purpose applications.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with a 50 V rated voltage and a capacitance tolerance of −20% to +20% (measured at 120 Hz, 20℃).
• Low and High Frequency Ripple Capability: Specified ripple handling of 430 mA at 120 Hz (low frequency) and 645 mA at 10 kHz (high frequency), enabling use where AC ripple performance is required.
• Loss Characteristics: Tangent of loss angle (tan δ) 0.12 measured at 20℃, 120 Hz, providing a defined dissipation characteristic for AC applications.
• Leakage Current: Leakage current specified at 330 µA, supporting predictable bias behavior after voltage application.
• Reliability & Endurance: Rated life of 2000 hours at 85℃ with specified limits for capacitance change, tan δ, and leakage current after endurance testing.
• Compact Mechanical Package: Radial lead can with φ10 × 12.5 mm body size (L: 1.25 cm × D: 1.0 cm), 5.0 mm lead spacing (±0.5 mm), and available in bulk or bag packing.
• Operating Range & Polarity: Polarized capacitor rated for −40℃ to 85℃ operation, targeted at general-purpose electronics.
• Regulatory Compliance: RoHS compliant.

Typical Applications

• General-purpose electronics — Compact radial-lead form factor and 220 µF/50 V rating suit a variety of general-purpose circuit needs where polarized capacitance is required.
• Power supply modules — Defined ripple current ratings at both low and high frequency make this part suitable for smoothing and decoupling in space-limited power assemblies.
• Industrial control equipment — Rated endurance of 2000 hours at 85℃ and a −40℃ to 85℃ operating range support stable performance in industrial ambient conditions.
• Consumer devices — Miniature can size and radial-lead packaging simplify integration into compact boards and assemblies used in consumer electronics with general-purpose power needs.

Unique Advantages

• Compact footprint: φ10 × 12.5 mm can and 5 mm lead spacing deliver high capacitance in a small radial-lead package for space-constrained designs.
• Dual-frequency ripple specification: Separate ripple current ratings at 120 Hz and 10 kHz provide clear guidance for both low- and high-frequency AC environments.
• Long endurance at elevated temperature: 2000 hour rated life at 85℃ gives predictable long-term performance for sustained thermal stress.
• Controlled electrical characteristics: Specified tan δ (0.12 at 20℃, 120 Hz) and defined leakage current (330 µA) support predictable circuit behavior and easier design validation.
• RoHS compliance: Environmentally compliant material set suitable for assemblies requiring RoHS status.
• Ready-to-integrate radial format: Standard radial leads and bulk/bag packing options simplify assembly and inventory handling.
