UHW1E222MHD

The UHW1E222MHD is a miniature aluminum electrolytic capacitor in a radial‑lead can designed for general‑purpose power and decoupling applications. It provides 2200 µF capacitance at 25 V with a compact φ12.5 × 25 mm case and is optimized for high ripple current and low impedance across a wide frequency range.

Engineered for reliability, this part delivers long endurance (10,000 hours at 105°C) and wide operating temperature range (‑40°C to 105°C), making it suitable for demanding embedded and industrial electronics where ripple handling and sustained performance matter.

Key Features

• Capacitance and Tolerance — 2200 µF (2.2 mF) nominal with tolerance −20% to +20% (±20% at 120 Hz, 20°C).
• Rated Voltage — 25 V DC rated voltage suitable for common power rail applications.
• Low Impedance — Specified impedance of 45 mΩ supports efficient energy delivery and reduced voltage ripple.
• High Ripple Current — Low‑frequency ripple current 2.4 A (120 Hz) and high‑frequency ripple current 3.2 A (10 kHz), backed by frequency coefficient behavior for higher frequencies.
• Loss Angle (tan δ) — tanδ = 0.15 (measured at 20°C, 120 Hz) for predictable AC loss characteristics.
• Reliability & Lifetime — Endurance rated for 10,000 hours at 105°C with capacitance and leakage criteria defined for post‑test performance.
• Temperature Range — Operable from −40°C to +105°C to cover a broad set of environmental conditions.
• Mechanical & Mounting — Radial lead, can package with φ12.5 mm diameter, 25 mm length, 5 mm lead spacing (±0.5 mm), and lead diameter 0.6 mm for through‑hole assembly.
• Leakage Current — Specified leakage current of 550 µA.
• Compliance — RoHS compliant.
• Packaging & Availability — Available in bulk (no terminal forming) or bag packing; status: mass production.

Typical Applications

• Power Supply Smoothing — Bulk capacitance and low impedance reduce output ripple and stabilize DC rails in switching and linear supplies.
• Decoupling and Bulk Storage — High ripple current capability and 2200 µF capacitance support transient current delivery for embedded systems and power modules.
• Industrial and Consumer Electronics — Compact radial lead package and long endurance suit general‑purpose power conditioning in control boards and consumer devices.

Unique Advantages

• High Ripple Handling: 2.4 A (120 Hz) and 3.2 A (10 kHz) ripple ratings enable reliable operation under sustained AC stress.
• Compact Footprint: φ12.5 × 25 mm case provides substantial capacitance in a small through‑hole package for space‑constrained designs.
• Low Effective Series Impedance: 45 mΩ impedance helps minimize voltage drop and heat generation under load.
• Long Endurance at Elevated Temperature: 10,000 hours at 105°C supports long service life in thermally demanding environments.
• Predictable AC Losses: Specified tanδ (0.15 at 20°C, 120 Hz) aids designers in thermal and ESR budgeting.
• Through‑Hole Robustness: Radial lead construction and defined lead spacing simplify PCB assembly and mechanical reliability for hand‑assembled and automated insertion processes.
