UKZ1E470MPM

The UKZ1E470MPM is a premium-grade aluminum electrolytic capacitor from Nichicon's UKZ "MUSE" acoustic series, designed for audio use. It is a radial lead, polarized can-type capacitor specified at 47 µF and 25 V, intended for first-class audio equipment where acoustic quality is required.

Key value propositions include audio-oriented electrical characteristics (low loss at audio frequencies), compact radial package dimensions, and compliance with RoHS directives.

Key Features

• Audio-Grade Construction — Part of Nichicon's premium "MUSE" acoustic series, explicitly intended for audio equipment and marked with gold on a black sleeve.
• Electrical Rating — 47 µF capacitance at 25 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Loss and Leakage Performance — tan δ (max.) of 0.12 at 120 Hz, 20°C for 25 V parts; typical leakage current specified as 11.75 µA (at 20°C after 1 minute) for this part number.
• Temperature and Endurance — Operating temperature range −40°C to +85°C; rated endurance of 1000 hours at 85°C with capacitance change within ±20% after the test.
• Low-Temperature Stability — Impedance ratios for the 25 V rating: Z(−25°C)/Z(+20°C) ≤ 2 and Z(−40°C)/Z(+20°C) ≤ 4, measured at 120 Hz.
• Compact Radial Package — Radial can with dimensions 10 × 12.5 mm (φD × L) and 5 mm lead spacing, suitable for through-hole layouts.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High-end Audio Equipment — Suited to first-class audio systems where acoustic performance and component quality contribute to sound character.
• Audio Signal and Coupling Circuits — Used where audio-oriented electrical characteristics such as low loss (tan δ) are beneficial.
• Audio Power Supply Filtering — Applied in power sections of audio devices that require stable capacitance and specified endurance at elevated temperatures.

Unique Advantages

• Designed for Audio — Part of the Nichicon MUSE acoustic series, explicitly targeted to audio use for consistent sonic characteristics.
• Measured Low Loss at Audio Frequencies — tan δ = 0.12 (max.) at 120 Hz for 25 V, supporting lower dissipation in audio-frequency signal paths.
• Compact Through-Hole Form Factor — 10 × 12.5 mm radial can with 5 mm lead spacing enables dense, serviceable PCB layouts in audio equipment.
• Robust Temperature and Endurance Specs — −40°C to +85°C operating range and 1000 hours endurance at 85°C with defined limits on capacitance, dissipation, and leakage.
• Traceable Leakage Specification — Leakage current specified (11.75 µA for this part at 20°C after 1 minute), allowing predictable design margining for bias and noise considerations.
• RoHS Compliance — Meets current RoHS directives for regulatory conformity in commercial audio products.
