UKW1H3R3MDD

The UKW1H3R3MDD from Nichicon is a radial-lead aluminum electrolytic capacitor optimized for audio and AV applications. It combines a compact radial can package with Nichicon’s audio-focused electrolyte formulation to support a harmonious balance of sound quality in space-constrained designs.

This polarized capacitor is rated 3.3 µF at 50 V with ±20% tolerance and is RoHS compliant. Key electrical characteristics include low dissipation factor, controlled leakage, and defined ripple current performance for both low- and high-frequency environments.

Key Features

• Capacitance & Voltage — Rated capacitance of 3.3 µF at 50 V with ±20% tolerance (measured at 120 Hz, 20 °C), suitable for small-signal and support functions in audio circuits.
• Audio-Optimized Electrolyte — Part of Nichicon’s UKW series developed for audio equipment, formulated to realize a harmonious balance of sound quality in AV applications.
• Low Dissipation Factor — tanδ of 0.12 measured at 20 °C and 120 Hz, indicating low dielectric losses for its rating.
• Ripple Current Capability — Handles 35 mA at 120 Hz (low frequency) and 70 mA at 10 kHz (high frequency), enabling reliable operation across common audio-related ripple conditions.
• Controlled Leakage — Specified leakage current of approximately 4.95 µA for predictable bias behavior in circuit designs.
• Endurance & Temperature Range — Rated for 2000 hours at 85 °C and an operating temperature range of −40 °C to +85 °C for stable long-term performance.
• Compact Radial Package — φ5×11L can with 2 mm lead spacing and overall dimensions L: 1.1 × D: 0.5 cm, providing a small footprint for compact PCBs.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• Audio equipment — Used in audio circuits where capacitor characteristics contribute to sound quality and stability.
• AV systems — Suitable for use in consumer and professional AV equipment, consistent with the UKW series focus on AV applications.
• Audio-focused modules — A compact radial option for modules or subassemblies that require a small electrolytic capacitor with defined ripple and leakage performance.

Unique Advantages

• Audio-oriented formulation: Nichicon’s UKW-series electrolyte is developed specifically to support a harmonious balance of sound quality in audio and AV designs.
• Compact footprint: φ5×11L radial can and 2 mm lead spacing provide a space-efficient solution for densely packed PCBs.
• Measured low-loss behavior: tanδ of 0.12 at 120 Hz and 20 °C supports predictable performance in low-frequency audio paths.
• Defined ripple handling: Rated ripple currents for both 120 Hz and 10 kHz frequencies allow designers to account for AC stress across typical audio and AV power conditions.
• Predictable leakage: Low leakage current (~4.95 µA) aids in bias stability for sensitive audio circuits.
• Durability under load: 2000 hours endurance at 85 °C provides a measurable life metric for design validation and reliability planning.
