UKW2A330MPD

The UKW2A330MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKW series, engineered for audio and AV equipment. It pairs a 33 µF capacitance with a 100 V rating in a compact φ8 × 11.5 mm can, delivering low loss and reliable performance for discrete through-hole designs.

Designed with a specialized electrolyte to support a harmonious balance of sound quality, this capacitor offers a low tangent of loss angle (tan δ = 0.08 at 100 V, 20°C, 120 Hz), defined ripple-current capability, and an endurance rating of 2000 hours at 85°C—attributes targeted at audio-focused assemblies and AV applications.

Key Features

• Audio-focused formulation New electrolyte development in the UKW series supports a balanced sound signature targeted for AV and audio equipment.
• Electrical performance 33 µF nominal capacitance with ±20% tolerance and a 100 V rated voltage for higher-voltage audio and AV circuits.
• Low loss (tan δ) tan δ = 0.08 (measured at 20°C, 120 Hz, at 100 V), reducing dissipation in signal- and power-related audio paths.
• Ripple current capability Rated ripple current of 160 mA at 120 Hz (low frequency) and 320 mA at 10 kHz (high frequency) for power-smoothing and decoupling in audio supplies.
• Reliability and endurance Life rating of 2000 hours at 85°C with specified limits on capacitance change, tan δ, and leakage after endurance testing.
• Compact radial package φ8 × 11.5 mm can with 3.5 mm lead spacing (±0.5 mm) for easy through-hole mounting and board-level integration.
• Leakage and polarization Low leakage current (specified 99 µA) and polarized construction for correct orientation in DC circuits.
• Compliance and packaging RoHS compliant; available in Bulk (No Terminal Forming) or Bag packing. Product status: Mass Production.

Typical Applications

• Audio equipment — Suited for AV receivers, amplifiers, and other audio modules where a balanced sound characteristic is desired.
• AV systems — Useful in consumer and professional AV assemblies that require through-hole capacitors with reliable ripple handling at audio and sub-audio frequencies.
• Through-hole PCB assemblies — Radial-lead format and compact φ8 × 11.5 mm size simplify placement in discrete, repairable board designs.

Unique Advantages

• Audio-optimized chemistry Electrolyte development in the UKW series is targeted to produce a harmonious balance of sound for AV-focused designs.
• Low dissipation for cleaner performance A tan δ of 0.08 at 100 V (120 Hz, 20°C) helps minimize losses in signal and power paths.
• Defined ripple capability across frequencies Separate low- and high-frequency ripple ratings (160 mA at 120 Hz, 320 mA at 10 kHz) provide predictable behavior in power-smoothing and decoupling roles.
• Compact, serviceable package Small φ8 × 11.5 mm can and 3.5 mm lead spacing allow density in compact through-hole designs while remaining easy to replace or service.
• Proven endurance 2000 hours at 85°C endurance rating gives a clear specification for lifecycle planning in thermal environments up to 85°C.
• Regulatory compliance RoHS compliance supports regulatory requirements for electronics manufacturing.
