UKW1V332MHD

The UKW1V332MHD is a radial-lead aluminum electrolytic capacitor designed for audio and AV equipment. It delivers 3.3 mF capacitance at a 35 V rating in a compact φ16 × 35.5 mm can with 7.5 mm lead spacing.

Engineered for power smoothing and decoupling in audio signal paths, the part combines high capacitance, measurable ripple-current capability, and a design life rated for 2000 hours at 85°C while remaining RoHS compliant.

Key Features

• Capacitance & Voltage — 3300 µF (3.3 mF) rated at 35 V with ±20% tolerance, providing significant bulk energy storage for power supply filtering in audio circuits.
• Ripple Current Performance — Low-frequency ripple current 2.22 A (120 Hz) and high-frequency ripple current 2.553 A (10 kHz), supporting both mains-frequency smoothing and higher-frequency decoupling.
• Loss Characteristics — Measured tangent of loss angle (tanδ) 0.18 at 20°C, 120 Hz, useful for evaluating dissipation in audio applications.
• Leakage Current — Specified leakage current of 3465 µA, enabling predictable bias behavior when designing circuits.
• Endurance & Temperature Range — Rated life of 2000 hours at 85°C and operating range from −40°C to 85°C for stable operation under elevated temperatures.
• Package & Mounting — Radial lead, can-style package (φ16 × 35.5 mm) with 7.5 mm lead spacing and bulk/bag packing options for through-hole assembly and manual or automated insertion.
• Audio-Optimized Electrolyte — Part of the UKW series developed for audio equipment with an electrolyte formulation intended to support a harmonious balance of sound quality.
• Compliance & Production — RoHS compliant and listed as mass production, suitable for volume designs.

Typical Applications

• Audio Amplifiers — Power supply smoothing and reservoir capacitance to stabilize rails and support dynamic audio peaks.
• AV Equipment — Bulk decoupling and filtering in consumer and professional audio/visual systems where the UKW series is targeted.
• Power Supply Filtering — Low-frequency and higher-frequency ripple handling for linear and switching supplies in audio electronics.

Unique Advantages

• High Energy Density: 3300 µF at 35 V provides substantial charge storage in a compact φ16 × 35.5 mm can, reducing board area for bulk capacitance.
• Dual-Frequency Ripple Capability: Specified ripple current at both 120 Hz and 10 kHz enables designers to address mains-frequency smoothing and higher-frequency decoupling with one component.
• Audio-Focused Electrolyte: Series-level development emphasizes sound quality, making the part well suited to AV and audio signal-chain designs.
• Durability at Elevated Temperature: 2000-hour life at 85°C provides predictable long-term behavior for systems exposed to higher operating temperatures.
• Through-Hole Mechanical Robustness: Radial-lead can and 7.5 mm lead spacing support reliable through-hole assembly and strong mechanical retention in enclosures.
• Regulatory Compliance: RoHS compliance simplifies regulatory management for commercial and consumer products.
