UKA1V331MPD

The UKA1V331MPD is a radial-lead aluminum electrolytic capacitor optimized for audio applications. It delivers 330 µF capacitance at 35 V in a compact φ10 × 12.5 mm can with 5 mm lead spacing, combining high capacitance density with a design suited to through-hole mounting.

Designed for demanding operating conditions, this part offers a wide temperature range (–55°C to 105°C), 2000 hours endurance at 105°C, and measurable low-loss characteristics—features that support reliable filtering and smoothing in audio and other electronic circuits.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance rated for 35 V, suitable for bulk decoupling and smoothing tasks.
• Low-loss Performance — tan δ (loss tangent) of 0.16 maximum at 20°C measured at 120 Hz, supporting stable audio performance by minimizing dissipation.
• Ripple Current Capability — Rated ripple current of 350 mA at 120 Hz and 525 mA at 10 kHz, with frequency coefficients defined in the series datasheet for higher-frequency operation.
• Leakage Current — Specified leakage current of 346.5 µA (as provided), enabling predictable bias behavior in DC-coupled stages.
• Wide Temperature & Endurance — Operating range from –55°C to 105°C and 2000 hours rated lifetime at 105°C for long-term reliability in thermal stress conditions.
• Mounting & Package — Radial lead, can-style package (φ10 × 12.5L) with 5 mm lead spacing; available in bulk (no terminal forming) and bag packing for production workflows.
• Qualification — AEC-Q200 listed in the product specifications, indicating component-level qualification for demanding electronic applications.

Typical Applications

• Audio Equipment — Used for power-supply filtering, decoupling and smoothing in high-grade audio circuits where stable capacitance and low loss are important.
• Power Supply Rails — Bulk decoupling and energy reservoir duties on through-hole power rails in consumer and professional electronics.
• Signal Conditioning — Coupling and smoothing in analog stages where consistent leakage and loss characteristics support predictable circuit behavior.

Unique Advantages

• High Capacitance in a Compact Can — 330 µF in a φ10 × 12.5 mm package provides significant decoupling capacity without a large PCB footprint.
• Measured Low Loss — tan δ of 0.16 at 120 Hz (20°C) helps maintain audio fidelity and minimizes heat generation under AC stress.
• Designed for Extended Thermal Stress — 2000 hours at 105°C endurance rating supports longer service life in warm environments.
• Frequency-aware Ripple Ratings — Specified ripple currents at 120 Hz and 10 kHz, with frequency coefficients in the series datasheet, let designers size capacitors for both low- and high-frequency ripple conditions.
• Production-friendly Packaging — Available in bulk and bag packing to support assembly and automated handling requirements.
• Component Qualification — AEC-Q200 listing provides an additional level of assurance for use in demanding systems.
