UES1V330MPM

The UES1V330MPM is a bi‑polar aluminum electrolytic capacitor from Nichicon’s UES "MUSE" acoustic series, designed specifically for audio signal circuits. It is a radial‑lead, can‑style component that combines audio‑focused construction with compact dimensions and RoHS compliance for use in audio equipment and signal‑path applications.

Key Features

• Capacitance & Voltage — 33 µF rated at 35 V, suitable for a variety of audio signal‑path requirements.
• Bi‑Polar Construction — Bi‑polar (non‑polarized) design intended for AC coupling and audio signal circuits.
• Package & Mounting — Radial, can package with radial leads and a 5 mm lead spacing for through‑hole PCB mounting.
• Size — Compact footprint: case dimensions L: 1.25 cm × D: 1.00 cm and a seated height of 1.25 cm.
• Temperature & Lifetime — Rated operating range −40°C to +85°C with a defined endurance of 1000 hours at 85°C (with polarity inversion per datasheet conditions).
• Loss & Stability — Tangent of loss angle (tan δ) max 0.14 at 35 V (measurement: 120 Hz, 20°C); low‑temperature impedance ratios Z(−25°C)/Z(+20°C)=2 and Z(−40°C)/Z(+20°C)=4.
• Leakage Current Spec — Leakage current specified as not more than 0.03 × C × V (µA) after 1 minute’s application of rated voltage at 20°C (series specification).
• Tolerance & Marking — Capacitance tolerance ±20% at 120 Hz, 20°C; marked with black lettering on a clear green sleeve.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio signal circuits — Intended use in AC‑coupled and signal‑path sections of audio equipment where bi‑polar capacitors are required.
• Audio equipment — Suited for components in amplifiers, preamplifiers, and other acoustic systems that use Nichicon’s MUSE acoustic series parts.
• Signal coupling and filtering — Use where stable capacitance, controlled loss (tan δ), and predictable leakage are needed in audio frequency ranges.

Unique Advantages

• Audio‑focused design: Part of the Nichicon MUSE acoustic series and specified for audio use, aligning component selection with acoustic performance goals.
• Bi‑polar capability: Bi‑polar construction supports AC coupling without polarity constraints, simplifying design in differential and audio paths.
• Compact radial can: Small case dimensions and 5 mm lead spacing enable space‑efficient, through‑hole layouts while retaining robust mechanical mounting.
• Measured electrical stability: Low tan δ (0.14 max at 35 V, 120 Hz, 20°C) and defined low‑temperature impedance ratios provide predictable behavior across temperature extremes.
• Durability under stress: Endurance specification of 1000 hours at 85°C with polarity inversion and defined post‑test limits for capacitance, tan δ, and leakage current.
• Regulatory compliance: RoHS compliance supports environmentally conscious product designs and procurement requirements.
