UKA1E221MPD

The UKA1E221MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKA series, designed for audio applications and wide temperature operation. It delivers 220 µF capacitance at a 25 V rating in a compact φ8 × 11.5 mm can with 3.5 mm lead spacing.

Built for demanding audio circuits, this part combines low loss (tan δ 0.18 at 20°C/120 Hz), defined ripple-current capability, and a 2000-hour endurance at 105°C to provide stable performance across a broad −55°C to 105°C operating range.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance rated at 25 V with ±20% tolerance for predictable energy storage.
• Low Loss — Tangent of loss angle (tan δ) specified at 0.18 (max) measured at 20°C and 120 Hz, supporting lower dissipation in signal-critical audio circuits.
• Ripple-Current Handling — Rated for 240 mA at 120 Hz (low frequency) and 360 mA at 10 kHz (high frequency) to support power smoothing and filtering in audio power rails.
• Leakage Current — Specified leakage current of 165 µA, enabling controlled standby and bias behavior.
• Temperature & Endurance — Wide operating range from −55°C to 105°C and an endurance rating of 2000 hours at 105°C for long-term stability under elevated temperature stress.
• Qualification — AEC-Q200 listed in product specifications to indicate component-level reliability screening.
• Mechanical & Packaging — Radial lead construction, polarized can package, dimensions φ8 × 11.5 mm with 3.5 mm lead spacing; available in bulk (no terminal forming) or bag packing for production handling.

Typical Applications

• High-grade audio equipment — Suited for use in audio electronics where the UKA series’ emphasis on audio performance and wide temperature range is required.
• Professional audio amplifiers and preamplifiers — Provides stable capacitance and low dissipation for power supply smoothing and signal-coupling roles in professional audio circuitry.
• Audio power-supply filtering — Rated ripple current and defined leakage characteristics make this capacitor appropriate for filtering and decoupling in audio power rails.

Unique Advantages

• Audio-focused performance: The UKA series is specified for high-grade audio equipment and the low tan δ helps minimize loss in signal-sensitive designs.
• Broad temperature capability: −55°C to 105°C operation ensures reliable behavior across harsh environmental and thermal conditions.
• Defined endurance: 2000 hours at 105°C gives designers a measurable life benchmark for thermal stress planning and reliability assessments.
• Frequency-aware ripple handling: Separate ripple-current specifications at 120 Hz and 10 kHz provide clear guidance for both low- and high-frequency filtering demands.
• Production-ready packaging: Available in bulk (no terminal forming) or bag packing to support volume assembly workflows.
• AEC-Q200 qualification: Component-level reliability screening included in the specifications to support applications that require established part qualification.
