UKT1E330MDD

The UKT1E330MDD is a Nichicon UKT series miniature radial-lead aluminum electrolytic capacitor designed for audio equipment. It delivers 33 µF at 25 V in a compact φ5 × 11 mm can with wide operating temperature range and specified endurance for demanding signal and power applications.

Engineered for compact audio designs, the UKT1E330MDD pairs small size and targeted electrical performance—low loss (tan δ), defined leakage, and frequency-specific ripple capability—to support decoupling, filtering and smoothing in audio circuits across a broad temperature range.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance rated at 25 V with a tolerance of -20% to 20% for predictable filtering and decoupling performance.
• Low loss (tan δ) — tan δ = 0.18 measured at 20°C, 120 Hz, supporting stable AC performance in audio-frequency circuits.
• Ripple current capability — Low-frequency ripple current 68 mA (120 Hz) and high-frequency ripple current 136 mA (10 kHz), enabling use where AC ripple handling at multiple frequencies is required.
• Leakage current and reliability — Specified leakage current of 24.75 µA for controlled DC leakage behavior in bias and supply circuits.
• Wide temperature & endurance — Operating range -55°C to 105°C with rated lifetime of 1000 hours at 105°C, suitable for equipment exposed to wide ambient variations.
• Compact radial package — φ5 × 11 mm can, radial lead mounting with 2.0 mm lead spacing (±0.5 mm), available in Bulk (No Terminal Forming) or Bag packing for PCB or manual assembly.
• Qualifications & compliance — AEC-Q200 listed in specifications and RoHS compliant, aligning with reliability and environmental requirements where specified.

Typical Applications

• Audio equipment power rails — Local decoupling and smoothing in audio amplifiers and preamplifiers where compact size and low-loss operation matter.
• Signal filtering — AC-coupling and low-frequency filtering in consumer and professional audio circuitry benefiting from defined tan δ and leakage characteristics.
• Compact electronic modules — Power conditioning in space-constrained audio modules and small form-factor devices due to the φ5 × 11 mm footprint.

Unique Advantages

• Small footprint for tight layouts: φ5 × 11 mm can and 2.0 mm lead spacing enable placement in compact PCB areas without compromising capacitance.
• Designed for audio use: Specified tan δ and ripple current values support reliable performance across audio-frequency and higher ripple environments.
• Wide temperature endurance: -55°C to 105°C rating and 1000 hours at 105°C provide durability in applications exposed to elevated temperatures.
• Predictable leakage behavior: Specified leakage current (24.75 µA) aids in bias stability and circuit design calculations.
• Supplier-backed qualification: AEC-Q200 listing (per specifications) and RoHS compliance indicate attention to reliability and environmental standards.
• Packaging flexibility: Available in Bulk (No Terminal Forming) or Bag packing to suit assembly and handling preferences.
