UVK1H2R2MDD

The UVK1H2R2MDD is a miniature aluminum electrolytic capacitor from Nichicon's UVK series, configured as a radial-lead, standard-type electrolytic. It delivers 2.2 µF capacitance at a 50 V rating in a compact φ5 × 11 mm can with 2 mm lead spacing, aimed at general-purpose circuit applications where a small electrolytic solution is required.

Key value stems from its combination of small size, defined ripple-current capability at low and high frequencies, controlled loss tangent (tan δ), and a 2000-hour endurance rating at 85°C, providing a predictable electrical footprint for compact designs.

Key Features

• Electrical Performance: 2.2 µF rated capacitance with ±20% tolerance and rated voltage 50 V; designed for general-purpose AC/DC decoupling and energy smoothing within that electrical envelope.
• Loss and Leakage Characteristics: Tangent of loss angle (tan δ) 0.12 measured at 20°C, 120 Hz, and leakage current specified at 4 µA under rated conditions for stable low-loss operation.
• Ripple Current Handling: Low-frequency ripple current 28 mA at 120 Hz and high-frequency ripple current 56 mA at 10 kHz, enabling use in applications with measurable ripple across the specified frequencies.
• Mechanical & Mounting: Radial lead package in a φ5 × 11 mm can with 2 mm lead spacing (±0.5 mm), suitable for through-hole mounting and straightforward PCB insertion.
• Reliability & Temperature Range: Rated operating range –40°C to +85°C with endurance of 2000 hours at 85°C under rated voltage, providing a defined lifetime profile for thermal and age planning.
• Packaging & Compliance: Available in bulk/no terminal forming or bag packing; RoHS-compliant. Product status: End Of Life.

Typical Applications

• General-purpose power filtering — 2.2 µF at 50 V in a compact package for decoupling and smoothing in low- to mid-voltage circuits.
• Compact PCB assemblies — φ5 × 11 mm can and 2 mm lead spacing offer a small footprint for space-constrained through-hole designs.
• Frequency-dependent ripple management — Defined ripple current ratings at 120 Hz and 10 kHz enable selection for circuits with known low- and high-frequency ripple profiles.

Unique Advantages

• Space-efficient form factor: Miniature φ5 × 11 mm can reduces board area compared with larger electrolytic alternatives while retaining radial-lead mounting simplicity.
• Predictable electrical behavior: Specified tan δ, leakage current, and tolerance make it straightforward to model AC loss and DC leakage in designs.
• Frequency-aware ripple specs: Separate ripple-current ratings at 120 Hz and 10 kHz help designers match capacitor selection to the application's ripple frequency content.
• Defined endurance profile: 2000 hours at 85°C under rated voltage gives a clear lifetime expectation for thermal aging and reliability planning.
• Regulatory compliance: RoHS-compliant construction supports environmental and regulatory requirements for electronic assemblies.
