UKZ1H330MPM

The UKZ1H330MPM is a premium-grade, audio-focused aluminum electrolytic capacitor from Nichicon's UKZ "MUSE" acoustic series. It is a polarized, radial-lead, can-style capacitor intended for use in high-quality audio equipment where low loss and reliable performance are required.

Key attributes include a 33 µF capacitance at 50 V, low loss characteristics (tan δ ≤ 0.08 at 120 Hz, 20°C for 50 V), RoHS compliance, and mechanical dimensions suited for compact radial mounting. The part is specified for operation from –40°C to +85°C with a rated endurance of 1000 hours at 85°C under rated voltage.

Key Features

• Audio-grade MUSE series – Designed as part of Nichicon's premium "MUSE" acoustic lineup for first-class audio equipment.
• Rated capacitance and voltage – 33 µF at 50 V, with capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• Low dielectric loss – Tangent of loss angle (tan δ) ≤ 0.08 at 50 V (measurement: 120 Hz, 20°C), supporting lower distortion in audio signal paths.
• Leakage current – Specified leakage current of 16.5 µA (measured at 20°C after 1 minute's application of rated voltage), suitable for precision audio circuits.
• Endurance and shelf life – Rated for 1000 hours at 85°C with rated voltage applied; after recovery to 20°C the part meets the endurance limits for capacitance change, tan δ, and leakage current.
• Package and mounting – Radial lead, can-style package with 5 mm lead spacing; case size listed as Ø10 × 12.5 mm (L: 1.25 × D: 1.0 cm).
• Operating temperature – −40°C to +85°C, suitable for a range of audio equipment environments.
• RoHS compliant – Meets the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High-end audio amplifiers – Use for signal coupling, decoupling, and power supply filtering where low loss and stable performance are important.
• Preamplifiers and DAC/ADC circuits – Suitable for audio signal paths that benefit from low tan δ and controlled leakage current.
• Audio power supplies – Bulk and smoothing applications in compact radial layouts where the 50 V rating and 33 µF value meet design needs.

Unique Advantages

• Audio-focused material and design – Part of Nichicon's MUSE acoustic series, explicitly positioned for first-class audio equipment.
• Low-loss performance – tan δ ≤ 0.08 at 50 V (120 Hz, 20°C) helps minimize distortion in audio paths.
• Compact radial can – Ø10 × 12.5 mm case and 5 mm lead spacing provide a space-efficient option for through-hole PCB layouts.
• Proven endurance specification – Rated for 1000 hours at 85°C under rated voltage with defined recovery limits, supporting predictable long-term behavior.
• Measured leakage current – Specified leakage of 16.5 µA (after 1 minute at 20°C) gives designers a verifiable parameter for precision circuits.
• Regulatory compliance – RoHS compliance ensures the part meets current EU restricted substances requirements.
