UHW1E222MHD6

The UHW1E222MHD6 is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can. It provides 2200 µF capacitance at a 25 V rating with low impedance and elevated ripple-current capability for general-purpose power conditioning in compact designs. Typical use cases include decoupling and bulk energy storage on power rails where a compact, long-life electrolytic is required.

Key Features

• Capacitance & Voltage: 2.2 mF (2200 µF) nominal capacitance with a 25 V rated voltage and ±20% tolerance at 20°C, 120 Hz.
• High Ripple-Current Performance: Low-frequency ripple current of 2.681 A at 120 Hz and high-frequency ripple current of 3.575 A at 10 kHz, supporting demanding AC ripple conditions.
• Low Impedance: Specified impedance of 45 mΩ, combined with the series' lower impedance at high frequency to improve filtering and transient response.
• Reliability & Endurance: Designed for 10,000 hours life at 105°C with defined limits for capacitance change, tan δ, and leakage after endurance testing.
• Leakage & Loss: Leakage current rated at 550 µA and tangent of loss angle (tan δ) of 0.15 (measured at 20°C, 120 Hz) for predictable dissipation behavior.
• Compact Radial Package: φ16 × 20L can with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assemblies; available in bulk/bag packing.
• Wide Operating Temperature: Specified operating range from −40°C to +105°C for use across typical industrial and consumer environments.
• RoHS Compliant: Manufactured in compliance with RoHS requirements as stated for the UHW series.

Typical Applications

• Power Supply Filtering: Bulk smoothing and ripple reduction on DC power rails where high ripple current and low impedance are required.
• DC-DC Converters: Input/output filtering and energy buffering in compact converter modules and power-management circuits.
• Industrial Control Electronics: Decoupling and transient energy support in controllers and drive circuits operating within −40°C to +105°C.
• Consumer and General-Purpose Electronics: Bulk capacitance for audio, communication, and general electronic subsystems that need reliable, long-life electrolytic support.

Unique Advantages

• High Ripple Capability: Rated ripple currents at both 120 Hz and 10 kHz enable effective AC ripple handling across low and high-frequency domains.
• Compact Footprint: φ16 × 20L radial can with 7.5 mm lead spacing delivers 2200 µF in a small through-hole package for space-constrained boards.
• Long Endurance at Elevated Temperature: 10,000 hours at 105°C provides predictable long-term performance in thermally demanding applications.
• Low Impedance for Improved Filtering: 45 mΩ impedance and the series’ lower high-frequency impedance characteristic improve transient suppression and stability of power rails.
• Measurable Dissipation and Leakage: Specified tan δ (0.15 at 20°C, 120 Hz) and leakage current (550 µA) simplify thermal and leakage budgeting during design.
• Regulatory Compliance: RoHS compliance supports use in products requiring restricted substance adherence.
