UKW1H330MDD

The UKW1H330MDD is a radial-lead aluminum electrolytic capacitor engineered for audio and AV applications. It combines a compact φ5 × 11 mm can with an audio-focused electrolyte formulation to support sound-quality sensitive designs.

Key electrical characteristics include 33 µF capacitance with ±20% tolerance, a 50 V rated voltage, low dissipation factor (tanδ = 0.12 at 20°C/120 Hz) and defined ripple current capability across low and high frequencies, making it suitable for compact analog and audio circuits operating between −40°C and 85°C.

Key Features

• Capacitance & Tolerance — 33 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated Voltage — 50 V working voltage for moderate-voltage audio and signal circuits.
• Audio-Optimized Electrolyte — Series design emphasizes harmonic balance for AV/audio equipment, derived from the UKW series development.
• Low Dissipation Factor (tanδ) — tanδ = 0.12 at 20°C, 120 Hz, supporting low-loss performance in signal-critical paths.
• Ripple Current Capability — 120 mA at 120 Hz (low frequency) and 240 mA at 10 kHz (high frequency), enabling stable performance under AC ripple stress.
• Low Leakage — Leakage current specified at 49.5 µA, supporting predictable bias performance after voltage application.
• Endurance — Rated lifetime of 2000 hours at 85°C with specified post-test limits on capacitance change, tanδ and leakage current.
• Compact Radial Package — φ5 × 11 mm can (L: 1.1 × D: 0.5 cm) with 2.0 mm lead spacing (±0.5 mm) for tight-board layouts and through-hole assembly.
• Environmental Compliance — RoHS compliant.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible procurement and assembly workflows.

Typical Applications

• Audio Equipment — Suited to analog and AV circuits where the UKW series' electrolyte helps realize balanced sound characteristics.
• Consumer AV Devices — Compact footprint and defined ripple performance make it appropriate for space-constrained audio/AV modules.
• Small Signal and Analog Circuits — Polarized radial form and low dissipation factor support use in signal-path and bias circuits within the specified temperature range.

Unique Advantages

• Audio-focused formulation: Developed electrolyte and series tuning target harmonious balance of sound quality appropriate for AV applications.
• Small footprint for dense assemblies: φ5 × 11 mm radial can and 2.0 mm lead spacing enable placement in compact through-hole designs.
• Defined high-frequency ripple capability: 240 mA at 10 kHz provides measurable performance for circuits exposed to higher-frequency ripple.
• Predictable long-term behavior: 2000-hour endurance at 85°C with defined limits on capacitance, tanδ and leakage supports reliability planning.
• Low-loss operation: tanδ of 0.12 at 120 Hz helps minimize energy dissipation in audio and analog paths.
• Regulatory compliance: RoHS compliance supports use in designs requiring lead-free environmental conformity.
