UKZ2A221MHM

The UKZ2A221MHM is a premium-grade aluminum electrolytic capacitor from Nichicon’s MUSE acoustic series, designed for audio applications where sonic quality and dependable electrical performance are required. This radial-lead, polarized can-type capacitor delivers 220 µF at 100 V with a ±20% tolerance and is RoHS compliant.

Engineered for use in first-class audio equipment, the UKZ2A221MHM combines audio-focused design attributes with defined endurance and temperature characteristics to support reliable operation across typical audio system environments.

Key Features

• Acoustic-focused design — Part of Nichicon’s premium MUSE acoustic series, optimized for first-class audio equipment as specified by the series description.
• Electrical specification — 220 µF capacitance at a 100 V rated voltage with ±20% tolerance, suitable for high-voltage audio circuits requiring bulk capacitance.
• Low loss and leakage — Datasheet specifies tan δ up to 0.07 at 100 V (measurement at 120 Hz, 20°C) and a leakage current of 0.01CV or less after 1 minute at 20°C, supporting low-noise audio performance.
• Temperature and endurance — Rated for –40°C to +85°C operation with endurance specified as 1000 hours at 85°C under rated voltage; after endurance testing capacitance change remains within ±20% and leakage current remains at or below initial specified values.
• Radial lead, can package — Radial lead mounting with 7.5 mm lead spacing in a radial can package; physical size listed as L: 3.55 × D: 1.6 cm and a maximum seated height of 1.398 inch.
• Identification — Marked with gold color lettering on a black sleeve for clear visual identification.
• RoHS compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863) as noted in the product description.

Typical Applications

• High-end audio systems — Intended for use in first-class audio equipment where acoustic performance and stable electrical characteristics are important.
• Audio power supply filtering — Bulk capacitance and 100 V rating support filtering and smoothing duties in audio power stages.
• Signal coupling and decoupling in audio circuits — Polarized aluminum electrolytic construction suitable for coupling/decoupling tasks in audio electronics.

Unique Advantages

• Acoustic-grade pedigree: Inclusion in Nichicon’s MUSE acoustic series signals design attention toward audio performance and sound quality needs.
• High-voltage capability: 100 V rating provides headroom for higher-voltage audio stages and robust system integration.
• Documented low loss and leakage: Specified tan δ and leakage current parameters support low-noise operation and predictable behavior after power application.
• Temperature and endurance assurances: Rated –40°C to +85°C with a defined 1000-hour endurance at 85°C, with post-test limits for capacitance, tan δ, and leakage current.
• Serviceable radial-lead format: Radial can package with 7.5 mm lead spacing simplifies manual assembly and through-hole placements on audio PCBs.
• Regulatory compliance: RoHS conformity supports use in designs requiring restricted-substance compliance.
