UHE1V222MHD

The UHE1V222MHD is a Nichicon UHE-series miniature aluminum electrolytic capacitor in a radial-lead can, offering 2200 µF capacitance at a 35 V rating. Engineered for general-purpose power electronics, it delivers low impedance and high reliability for applications that require sustained ripple handling and long endurance.

Key design attributes include a compact φ16 × 30.5 mm can, 7.5 mm lead spacing, RoHS compliance, and an endurance specification of 10,000 hours at 105°C, making it suitable for demanding thermal and ripple conditions within its specified limits.

Key Features

• Capacitance & Voltage: 2.2 mF (2200 µF) nominal capacitance with a rated voltage of 35 V and tolerance of −20% to +20% for predictable energy storage.
• Low Impedance: Specified impedance of 50 mΩ supports effective smoothing and decoupling in power circuits.
• High Ripple Handling: Rated low-frequency ripple current of 2.76 A at 120 Hz and high-frequency ripple current of 3.45 A at 10 kHz for robust performance across frequencies.
• Reliability & Endurance: Life rating of 10,000 hours at 105°C per UHE series endurance specifications, with defined limits for capacitance change, tan δ, and leakage after endurance testing.
• Electrical Losses: Tangent of loss angle (tan δ) of 0.14 measured at 20°C, 120 Hz, supporting low dissipation in AC conditions.
• Leakage Current: Specified leakage current of 770 µA, measured per product test conditions.
• Form Factor & Mounting: Radial lead can (φ16 × 30.5 mm) with 7.5 mm lead spacing and lead spacing tolerance ±0.5 mm; available in bulk (no terminal forming) or bag packing.
• Operating Range & Compliance: Operating temperature −40°C to +105°C; RoHS compliant.

Typical Applications

• General-Purpose Power Electronics: Provides bulk energy storage and smoothing for power supplies and regulator output stages where 2200 µF/35 V bulk capacitance and high ripple handling are required.
• DC Link and Filtering: Suited for DC-link filtering and decoupling tasks in circuits that demand low impedance and sustained ripple current capability across low and high frequencies.
• Embedded and Industrial Controls: Compact radial-lead package fits into space-constrained boards for control and industrial power modules needing long-life capacitors rated to 105°C.

Unique Advantages

• Measured Ripple Performance: Explicit ripple current ratings at 120 Hz (2.76 A) and 10 kHz (3.45 A) let designers size capacitors against real operating conditions.
• Long-Term Endurance: 10,000 hours at 105°C per UHE series specifications supports reliability planning in thermally challenging environments.
• Low Dissipation Factor: tan δ = 0.14 (20°C, 120 Hz) contributes to reduced heating and stable performance under AC excitation.
• Compact Radial Format: φ16 × 30.5 mm can with 7.5 mm lead spacing simplifies PCB layout for through-hole assemblies while preserving high capacitance density.
• RoHS Compliant: Meets RoHS directive requirements for environmentally restricted substances.
• Production Availability: Listed as mass production status with packaging options suited to assembly and stocking needs.
