UHE1E222MHD

The UHE1E222MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UHE series. It is a radial-lead, polarized capacitor rated at 2200 µF and 25 V, designed for general-purpose electronic circuits that require low impedance, sustained ripple handling and long operating life.

Key value comes from a compact φ12.5 × 35.5 mm can, robust electrical performance (low impedance and high ripple current capability), and extended endurance up to 10,000 hours at 105°C.

Key Features

• Capacitance & Tolerance — 2200 µF nominal capacitance (2.2 mF) with tolerance of −20% to +20% at 120 Hz, 20°C.
• Rated Voltage — 25 V DC rating suitable for low-voltage power circuits.
• Low Impedance — Specified impedance of 65 mΩ supports improved transient response and lower voltage drop under load.
• Loss Factor (tan δ) — tan δ = 0.16 measured at 20°C, 120 Hz, indicating stable AC loss characteristics for the rated conditions.
• High Ripple Current Capacity — Low-frequency ripple current 2.304 A at 120 Hz and high-frequency ripple current 2.88 A at 10 kHz for effective smoothing across frequency ranges.
• Leakage Current — Specified leakage current of 550 µA.
• Long Life / High Temperature Endurance — Rated for 10,000 hours at 105°C, supporting extended operational lifetime in elevated-temperature environments.
• Package & Mounting — Radial lead, can package with dimensions φ12.5 × 35.5 mm and lead spacing 5 mm (±0.5 mm); offered in bulk (no terminal forming) or bag packing.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-purpose power filtering — Bulk and decoupling capacitance in low-voltage DC power rails where sustained ripple handling and long life are required.
• Power supply smoothing — Smoothing of rectified outputs and intermediate bus filtering at up to 25 V systems.
• Embedded electronics — Space-efficient energy storage and ripple suppression in compact radial-lead designs.

Unique Advantages

• Extended high-temperature life: 10,000-hour endurance at 105°C reduces maintenance and replacement frequency in demanding thermal environments.
• Wide operating temperature range: −40°C to 105°C supports reliable operation across broad environmental conditions.
• High ripple capability across frequencies: Defined ripple performance at 120 Hz (2.304 A) and 10 kHz (2.88 A) provides predictable behavior for both line-frequency and higher-frequency noise.
• Low effective series impedance: 65 mΩ impedance helps minimize voltage ripple and improve dynamic response in power circuits.
• Compact radial package: φ12.5 × 35.5 mm can with 5 mm lead spacing provides a small-footprint solution for through‑hole assemblies.
• Regulatory compliance: RoHS conformity supports restriction-of-hazardous-substances requirements.
