UKW1V330MDD

The UKW1V330MDD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKW series, specified at 33 µF and 35 V with polarized terminals. Designed for audio and AV equipment, the UKW series emphasizes sound quality through a specially developed electrolyte and is described as suited for AV applications.

This part offers a compact φ5 × 11 mm can in a radial package with a 2 mm lead spacing, RoHS compliance, and an endurance rating of 2000 hours at 85°C. Status: End Of Life.

Key Features

• Capacitance and Voltage — 33 µF rated capacitance at 35 V with ±20% tolerance, suitable for audio decoupling and smoothing tasks.
• Low Loss (tan δ) — tan δ = 0.14 (max) measured at 20°C and 120 Hz for the 35 V rating, indicating controlled dissipation at audio frequencies.
• Ripple Current Capability — 105 mA at 120 Hz (low frequency) and 210 mA at 10 kHz (high frequency), supporting both power-supply filtering and higher-frequency decoupling.
• Leakage Current — Specified leakage current of 34.65 µA, measured under the defined test conditions for stable bias behavior.
• Endurance and Temperature Range — 2000 hours life at 85°C and operational range from −40°C to +85°C for elevated-temperature stability.
• Package and Mounting — Radial can (φ5 × 11 mm), lead spacing 2 mm (±0.5 mm), supplied in bulk or bag packing (no terminal forming).
• Compliance — RoHS compliant.

Typical Applications

• Audio/AV Equipment — Designed for audio signal paths and power smoothing in AV systems where tonal balance and stable filtering are required.
• Power Supply Decoupling — Provides bulk capacitance and ripple handling for low-voltage DC rails in compact assemblies.
• Compact Consumer Electronics — Small φ5 × 11 mm can and radial-lead mounting suit space-constrained circuit boards in consumer AV devices.

Unique Advantages

• Audio-focused electrolyte development — The UKW series formulation is intended to support a harmonious balance of sound quality for AV applications.
• Measured low-loss performance at audio frequencies — tan δ of 0.14 at 120 Hz (35 V) helps minimize dissipation in audio-frequency filtering.
• Dual-frequency ripple handling — Specified ripple currents at both 120 Hz and 10 kHz allow designers to address both mains-frequency smoothing and higher-frequency decoupling with one part.
• Small radial-can footprint — φ5 × 11 mm package and 2 mm lead spacing enable placement in compact PCB layouts.
• Defined endurance — 2000 hours at 85°C provides a clear reliability expectation for elevated-temperature applications.
• RoHS compliant — Conforms to applicable material restrictions for regulatory compliance in many markets.
