UFW1H220MDD

The UFW1H220MDD is a radial-lead aluminum electrolytic capacitor with 22 µF capacitance and a 50 V rated voltage. It is part of Nichicon’s UFW series, specified for standard audio equipment applications.

Compact and durable, this capacitor offers a defined dissipation factor (tanδ = 0.12 at 20°C, 120 Hz), low leakage, and specified ripple current capability, along with a temperature range of −40°C to +85°C and 2000 hours endurance at 85°C.

Key Features

• Electrical Specification — Rated capacitance 22 µF with tolerance −20% to +20% and rated voltage 50 V.
• Dissipation Factor — tanδ 0.12 measured at 20°C and 120 Hz, providing a specified loss characteristic for design verification.
• Leakage Current — Leakage current specified at 33 µA for predictable bias behavior after voltage application.
• Ripple Current Capability — Low-frequency ripple current 95 mA at 120 Hz and high-frequency ripple current 190 mA at 10 kHz, with frequency coefficients available in the series datasheet.
• Reliability & Endurance — Life endurance of 2000 hours at 85°C under rated voltage conditions per series specification.
• Operating Range — Wide operating temperature range from −40°C to +85°C for varied environmental conditions.
• Mechanical & Packaging — Compact radial can package, physical size φ5 × 11 mm, lead spacing 2.0 mm (±0.5 mm), and available in bulk or bag packing (no terminal forming).
• Polarized Construction — Polarized aluminum electrolytic design for DC applications requiring electrolytic capacitance.

Typical Applications

• Audio Equipment — Designed for standard audio equipment as part of the UFW series; suitable where a compact 22 µF, 50 V electrolytic capacitor is required.
• Power Filtering in Small Form-Factor Electronics — Provides defined capacitance and ripple current handling in compact radial-can layouts for localized filtering tasks.
• General Purpose Electronics — Useful wherever a polarized aluminum electrolytic with the listed electrical and environmental ratings is appropriate.

Unique Advantages

• Compact Footprint: φ5 × 11 mm radial-can package and 2.0 mm lead spacing enable use in space-constrained PCB layouts.
