UKZ1H331MHM

The UKZ1H331MHM is a premium-grade, polarized aluminum electrolytic capacitor from Nichicon’s MUSE acoustic series, designed for audio applications. As a radial-lead, can-style capacitor rated at 330 µF and 50 V, it targets first-class audio equipment and other audio-focused designs that require reliable, low-loss electrolytic filtering and coupling.

Key value comes from audio-focused electrical characteristics and mechanical packaging: low dissipation (tan δ), controlled leakage, RoHS compliance, and a specification-driven lifetime for elevated operating temperatures.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, suitable for buffering and energy storage in audio circuits.
• Audio-Targeted Series — Part of Nichicon’s Premium “MUSE” acoustic series; specified for audio use and positioned for first-class audio equipment.
• Low Loss — Specified tangent of loss angle (tan δ) of 0.08 at 50 V (measurement frequency 120 Hz, 20°C), supporting low dissipation in AC audio paths.
• Leakage Performance — Leakage current defined as 0.01CV or less after one minute at 20°C, with the part-specific leakage current listed as 165 µA (after 1 minute at 20°C).
• Mechanical & Mounting — Radial lead, can package with 7.5 mm lead spacing and physical dimensions L: 3.05 × D: 1.6 cm (16 × 30.5 mm), for through-hole assemblies.
• Temperature & Lifetime — Rated operating temperature range of −40°C to +85°C with an endurance rating of 1000 hours at 85°C.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).
• Visual Identification — Marked with gold lettering on a black sleeve for clear part identification.

Typical Applications

• High-end audio equipment — Suited to first-class audio systems where the MUSE acoustic series specification is sought.
• Audio signal circuits — Appropriate for polarized capacitor functions in audio circuitry that require low dissipation and defined leakage characteristics.
• Through-hole audio assemblies — Radial lead, can package and 7.5 mm lead spacing make it suitable for conventional through-hole PCBs in consumer and professional audio products.

Unique Advantages

• Audio-focused specification: Part of Nichicon’s MUSE acoustic series and explicitly specified for audio use, aligning component selection with audio design goals.
• Low dissipation (tan δ = 0.08): Reduces loss in AC audio paths, helping preserve signal integrity in coupling and filtering applications.
• Defined leakage performance: 0.01CV or less (general spec) and 165 µA listed for this part after 1 minute at 20°C, enabling predictable bias and charge behavior.
• Through-hole packaging: Radial lead, can-style package with 7.5 mm lead spacing simplifies mounting in conventional PCB assemblies.
• Robust temperature endurance: −40°C to +85°C operating range and 1000 hours endurance at 85°C provide specification-backed reliability for elevated-temperature operation.
• Regulatory compliance: RoHS-compliant construction supports environmentally regulated product builds.
