UKZ1E221MHM

The UKZ1E221MHM is a premium-grade aluminum electrolytic capacitor from Nichicon’s UKZ MUSE acoustic series, specified for audio applications. It delivers 220 µF capacitance at a 25 V rating in a compact radial-can package intended for first-class audio equipment where audio quality and component reliability are priorities.

Designed for radial-lead PCB mounting, this part combines audio-oriented electrical characteristics with a RoHS-compliant construction and defined endurance for dependable service in professional and high-fidelity audio assemblies.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Audio-grade Performance — Specified as part of the Nichicon MUSE acoustic series, optimized for use in high-grade audio equipment.
• Loss and Leakage Characteristics — Maximum tan δ of 0.12 (25 V, 120 Hz, 20°C) and a specified leakage current of 55 µA (measured at 20°C after 1 minute), supporting low-loss audio applications.
• Reliability and Endurance — Rated for 1000 hours at 85°C with defined endurance limits: capacitance change within ±20%, tan δ ≤150% of initial spec, and leakage current not exceeding initial specified value after test.
• Operating Range — Operating temperature range of −40°C to +85°C to accommodate a wide range of audio system environments.
• Package and Mounting — Radial, can-style aluminum electrolytic with 5 mm lead spacing; case dimensions: 12.5 mm diameter × 20 mm length (L: 2.0 cm × D: 1.25 cm).
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Identification — Marked with gold-colored printing on a black sleeve for easy visual identification in assemblies.

Typical Applications

• High-fidelity audio equipment — Suited for premium audio devices where acoustic performance and component quality are required.
• Professional audio assemblies — Intended for use in professional audio systems that specify audio-grade components from the MUSE series.
• Audio electronics manufacturing — Suitable for board-level implementation in audio-focused product lines requiring radial-can electrolytic capacitors.

Unique Advantages

• Audio-focused design: Part of Nichicon’s MUSE acoustic series specifically described as “for audio use,” aligning component selection with audio performance goals.
• Verified electrical characteristics: Low tan δ (0.12 max at 25 V) and defined leakage current (55 µA) provide measurable, audio-relevant electrical behavior.
• Compact radial can package: 12.5 mm × 20 mm footprint with 5 mm lead spacing offers a space-efficient option for PCB layouts in audio equipment.
• Thermal endurance: Rated 1000 hours at 85°C with post-test limits for capacitance, tan δ, and leakage current to support predictable life performance.
• Regulatory compliance: RoHS conformity supports deployment in regions requiring restricted substances compliance.
• Clear visual marking: Gold printing on a black sleeve aids identification during assembly and maintenance.
