UKW1E221MPD

The UKW1E221MPD is a radial‑lead aluminum electrolytic capacitor from Nichicon’s UKW series, designed specifically for audio and AV equipment. It provides 220 µF capacitance at a 25 V rating with audio-oriented electrolyte development and electrical characteristics tailored for signal and power circuits in audio applications.

Compact and polarization-aware, this component combines a small φ8 × 11.5 mm can with measured ripple handling and long endurance for stable performance in designs operating between −40°C and 85°C.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 25 V with ±20% tolerance (120 Hz, 20°C).
• Audio‑oriented Electrolyte — UKW series development emphasizes a balanced sound quality, making this part targeted for audio and AV equipment.
• Loss Angle (tan δ) — tanδ = 0.16 measured at 20°C, 120 Hz (rated voltage 25 V).
• Ripple Current Capability — Low‑frequency ripple current 320 mA (120 Hz) and high‑frequency ripple current 480 mA (10 kHz), supporting applications with AC ripple considerations.
• Leakage Current — Specified leakage current of 165 µA for predictable idle and powered behavior.
• Endurance — Rated life of 2000 hours at 85°C with defined limits for capacitance change, tanδ, and leakage current after the endurance test.
• Mechanical & Packaging — Radial lead (polarized) can, size φ8 × 11.5 mm (L: 1.15 × D: 0.8 cm), lead spacing 3.5 mm (±0.5 mm). Available in bulk or bag packing (no terminal forming).
• Environmental Compliance — RoHS‑compliant construction.
• Marking — Printed with gold color lettering on a black sleeve for clear identification.

Typical Applications

• Audio Equipment — Suited for audio circuits and AV equipment where 220 µF/25 V capacitance, low tanδ and series‑defined endurance are required.
• AV Systems — Designed for use in AV product designs that require compact electrolytic capacitance with defined ripple handling at both low and high frequencies.
• Signal and Power Modules in Consumer Electronics — Compact radial can and controlled leakage current make it appropriate for board‑level use in consumer audio modules and related electronics.

Unique Advantages

• Audio‑focused formulation: The UKW series electrolyte development targets a harmonious balance of sound quality, aligning component characteristics with audio system requirements.
• Compact radial package: φ8 × 11.5 mm can with 3.5 mm lead spacing provides a small footprint for space‑constrained audio and AV PCBs.
• Defined ripple endurance: Specified ripple currents (320 mA at 120 Hz, 480 mA at 10 kHz) allow designers to match capacitor selection to expected ripple environments.
• Robust temperature life: 2000 hours at 85°C endurance rating supports reliable operation across the component’s −40°C to 85°C category temperature range.
• Predictable electrical behavior: Clear specifications for tanδ, leakage current (165 µA), and tolerance (±20%) enable accurate BOM and performance tradeoffs.
• Regulatory compliance: RoHS‑compliant construction supports environmental requirements for commercial audio products.
