UHE1H222MHD6

The UHE1H222MHD6 from Nichicon is a radial lead aluminum electrolytic capacitor in the UHE series, designed for high reliability and compact installations. It delivers 2.2 mF (2200 µF) capacitance at a rated voltage of 50 V in a miniature φ18 × 35.5 mm can with 7.5 mm lead spacing.

Engineered for demanding, general‑purpose power applications, this capacitor combines long life (10,000 hours at 105°C), low impedance (46 mΩ), and robust ripple handling (2.944 A @120 Hz, 3.68 A @10 kHz) in a RoHS‑compliant, mass‑production part available in bulk or bag packing.

Key Features

• Electrical Performance — Capacitance & Voltage: 2200 µF nominal capacitance with a rated voltage of 50 V and tolerance of −20% to +20% for bulk energy storage and smoothing.
• Low Impedance: Measured impedance of 46 mΩ helps minimize voltage drop and improve dynamic response in power circuits.
• High Ripple Current Capability: Low‑frequency ripple current of 2.944 A (120 Hz) and high‑frequency ripple current of 3.68 A (10 kHz) for effective ripple suppression across a range of switching and line frequencies.
• Long Life / Endurance: Rated for 10,000 hours at 105°C under DC bias plus rated ripple current, offering extended service life in elevated‑temperature environments.
• Temperature Range: Rated operating temperature −40°C to +105°C for broad environmental tolerance.
• Dissipation & Leakage: Dissipation factor (tan δ) of 0.12 (20°C, 120 Hz) and leakage current of 1100 µA as specified for quality control and design margin calculations.
• Package & Mounting: Radial lead (can) package, size φ18 × 35.5 mm, lead spacing 7.5 mm (±0.5 mm), supplied in bulk (no terminal forming) or bag packing for assembly flexibility.
• Compliance & Availability: RoHS compliant and in mass production as part of Nichicon’s UHE series.

Typical Applications

• General‑purpose power electronics: Bulk capacitance and ripple handling for power supply smoothing where 2200 µF at 50 V is required.
• Industrial equipment: Energy buffering and decoupling in systems that operate across −40°C to +105°C and demand long endurance (10,000 hours at 105°C).
• High‑frequency switching supplies: Effective at both low and high ripple frequencies, supporting up to 3.68 A ripple current at 10 kHz for switching regulator output filtering.

Unique Advantages

• High capacitance in a compact can: 2200 µF packaged in a φ18 × 35.5 mm body reduces board footprint while maintaining bulk energy storage.
• Low impedance for improved regulation: 46 mΩ impedance helps lower AC voltage drop and supports stable power delivery under transient loads.
• Wide ripple frequency capability: Specified ripple currents at 120 Hz and 10 kHz provide predictable performance across mains and switching frequencies.
• Long elevated‑temperature life: 10,000‑hour endurance at 105°C contributes to longer mean time between maintenance in harsh thermal environments.
• Through‑hole ease of assembly: Radial lead form and standard 7.5 mm lead spacing simplify prototyping and through‑hole production processes.
• Regulatory readiness: RoHS compliance supports environmental and manufacturing requirements.
