UKZ1H221MHM

The UKZ1H221MHM is a premium-grade aluminum electrolytic capacitor from Nichicon’s UKZ "MUSE" acoustic series, configured as a radial lead can. It delivers 220 µF at 50 V with polarization and is specifically intended for audio equipment and first-class audio applications where audible performance and reliability matter.

Key value propositions include low loss at audio frequencies, compact radial can packaging, and defined endurance and temperature ratings for stable operation in typical audio system environments.

Key Features

• Electrical Performance — 220 µF nominal capacitance at 50 V with ±20% tolerance; low tangent of loss angle (tan δ) of 0.08 measured at 120 Hz, 20 °C, supporting low-loss audio circuitry.
• Leakage and Stability — Leakage current specified at 110 µA (at 20 °C after 1 minute), enabling predictable bias behavior in amplifier and power circuits.
• Temperature & Endurance — Rated operating temperature range of −40 °C to +85 °C and endurance of 1000 hours at 85 °C with capacitance change within ±20% after the test.
• Audio-focused Design — Part of the nichicon MUSE acoustic series, designed and marketed for audio use with an anti-solvent feature noted in series documentation.
• Mechanical & Mounting — Radial lead, can-style package with case size approximately 16 × 25 mm (D × L) and 7.5 mm lead spacing for through-hole board mounting and secure mechanical retention.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), meeting current restricted-substance directives.

Typical Applications

• High-fidelity amplifiers — Power supply smoothing and decoupling in amplifier stages where low loss and stable bias are important for audio quality.
• Preamplifiers and signal paths — Coupling and decoupling in signal circuits within first-class audio equipment that require audio-oriented capacitor characteristics.
• Audio power supplies — Bulk and local filtering in audio power rails, leveraging the capacitor’s rated voltage and endurance at elevated temperature.
• Home and professional audio equipment — Integration into consumer and professional audio products that specify MUSE-series components for audible performance preferences.

Unique Advantages

• Audio-tuned specification: Part of Nichicon’s MUSE acoustic series with an explicit focus on audio use, providing design alignment with first-class audio equipment requirements.
• Low-loss behavior: tan δ of 0.08 at 50 V (120 Hz, 20 °C) helps minimize dissipation in audio-frequency circuits.
• Predictable leakage: Specified leakage current (110 µA at 20 °C after 1 minute) supports consistent bias and performance in DC-coupled designs.
• Thermal endurance: Rated for −40 °C to +85 °C with 1000 hours endurance at 85 °C, delivering a defined lifetime for thermal reliability planning.
• Thru-hole, radial can form factor: 16 × 25 mm package with 7.5 mm lead spacing provides a compact, mechanically robust option for board-level designs.
• RoHS compliant: Conforms to 2011/65/EU and (EU)2015/863 restricted-substance requirements for regulatory alignment.
