UKZ1E471MHM

The UKZ1E471MHM is a premium-grade aluminum electrolytic capacitor from Nichicon’s MUSE acoustic series, designed specifically for audio equipment. It provides 470 µF capacitance at a 25 V rating in a radial-can package, making it suitable for use where audio performance and component reliability are priorities.

Engineered for audio applications, this capacitor combines acoustic-focused design intent with verified electrical characteristics such as defined tan δ and leakage current limits, a wide operating temperature range, and a specified endurance at elevated temperature.

Key Features

• Electrical Rating — 470 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Audio‑Focused Design — Part of the nichicon MUSE acoustic series and described as "For Audio Use" and "ideally suited for first class audio equipment."
• Loss and Leakage Characteristics — Maximum tan δ of 0.12 at 25 V (measurement at 120 Hz, 20°C) and leakage current specified as 0.01CV or less after one minute at 20°C.
• Low‑Temperature Stability — Impedance stability characterized with Z(–25°C)/Z(+20°C) = 2 and Z(–40°C)/Z(+20°C) = 4 for the 25 V rating (measurement at 120 Hz).
• Reliability & Endurance — Rated for 1000 hours at 85°C with endurance criteria: capacitance change within ±20%, tan δ ≤ 150% of initial spec, and leakage current ≤ initial specified value after test.
• Physical & Mounting — Radial lead, radial can package with 7.5 mm lead spacing and dimensions approximately L: 2.5 cm × D: 1.6 cm; marked in gold on a black sleeve for easy identification.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑end Audio Equipment — Intended for first-class audio systems where sonic character and component consistency are important.
• Amplifier Power Supply Decoupling — Bulk and smoothing capacitance in audio amplifier power rails within the 25 V range.
• Studio and Consumer Audio Electronics — Use in audio equipment chassis where radial lead components are required and long-term endurance at elevated temperature is necessary.

Unique Advantages

• Audio‑centric Heritage: Being part of the nichicon MUSE acoustic series associates the capacitor with an audio-focused design intent suitable for first-class audio equipment.
• Measured Loss and Leakage Specs: Specified tan δ (0.12 max at 25 V) and leakage current (0.01CV or less after 1 minute at 20°C) allow designers to budget for dissipation and bias currents with confidence.
• Defined Low‑Temperature Performance: Published impedance ratios at –25°C and –40°C provide predictable behavior for audio systems operating across the rated temperature range.
• Endurance Characterization: 1000 hours at 85°C with defined post-test limits ensures designers can assess long-term stability for thermal stress conditions.
• Clear Identification: Gold printing on a black sleeve simplifies part identification during assembly and maintenance.
• Regulatory Compliance: RoHS conformity supports designs targeting restricted-substance requirements.
