UKW1E153MRD

The UKW1E153MRD is a Nichicon UKW series aluminum electrolytic capacitor in a radial-lead can, offering 15,000 µF capacitance at a 25 V rating. It is part of a family developed specifically for audio and AV equipment, with an electrolyte formulation intended to support a harmonious balance of sound quality.

Engineered for high bulk energy storage and power filtering in audio systems, this polarized capacitor combines high capacitance, defined ripple handling, and a compact φ18 × 35.5 mm can for through-hole designs. It is RoHS compliant.

Key Features

• High Capacitance: 15,000 µF bulk capacitance for power smoothing and energy reserve in audio power rails.
• Rated Voltage: 25 V rated working voltage suitable for mid-voltage audio supply rails.
• Capacitance Tolerance: ±20% at 120 Hz, 20°C, allowing predictable design margins.
• Dielectric Loss (tan δ): tan δ = 0.52 measured at 20°C, 120 Hz (product specification).
• Ripple Current Handling: Specified ripple current performance of 3.8 A at 120 Hz and 4.37 A at 10 kHz; frequency coefficients in the UKW series indicate retention of ripple capability at higher frequencies (for 1000–15000 µF the coefficient is 1.00 at 120 Hz and 1.15 at ≥10 kHz).
• Leakage Current: Leakage current listed as 4,500 µA (per product data).
• Endurance: Rated for 2,000 hours at 85°C with post-test limits: capacitance change within ±20%, tan δ within 200% of initial specification, and leakage current within initial specified value.
• Operating Temperature Range: −40°C to +85°C for use across typical audio equipment ambient conditions.
• Radial Lead Can Package: φ18 × 35.5 mm can with 7.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing for through-hole assembly.
• Series Design Focus: UKW series marketed for audio/AV equipment with electrolyte and construction optimized for sound-quality-focused applications.
• Compliance: RoHS compliant.

Typical Applications

• AV and Home Audio Equipment: Bulk filtering and supply smoothing for AV receivers, amplifiers and related audio subsystems where high-capacitance energy reserve is required.
• Audio Power Amplifiers: Reservoir capacitor for amplifier rails to support transient current demands and maintain stable supply voltage under load.
• Consumer AV Electronics: Power supply decoupling and smoothing in CD players, tuners, and other audio/AV devices specified for the UKW series.

Unique Advantages

• Large Stored Energy in a Compact Can: 15,000 µF in a φ18 × 35.5 mm package provides significant bulk capacitance while conserving board area.
• Audio-Focused Electrolyte: Series design emphasizes balanced sound characteristics, supporting designers building audio-focused products.
• Defined Endurance Margins: 2,000-hour endurance at 85°C with clearly specified post-test limits helps predict long-term behavior in thermal-stressed systems.
• Frequency-Aware Ripple Performance: Specified ripple currents at 120 Hz and 10 kHz and series frequency coefficients allow designers to assess both low- and high-frequency ripple capability.
• Through-Hole Mounting Simplicity: Radial lead can and standard 7.5 mm lead spacing facilitate straightforward PCB layout and assembly for legacy or high-current audio designs.
• Regulatory Compliance: RoHS compliance supports conformity to environmental requirements in commercial electronics.
