UKW1E222MHD

The UKW1E222MHD is a Nichicon UKW series aluminum electrolytic capacitor optimized for audio and AV equipment. It is a polarized, radial-lead can-type capacitor offering 2,200 µF capacitance at a 25 V rating, designed to provide bulk energy storage and smoothing in through-hole audio power and signal circuits.

Its design balances sound-focused performance with practical electrical and mechanical specifications, including measurable low-frequency and high-frequency ripple capability, a wide operating temperature range, and a defined 2,000-hour endurance at elevated temperature.

Key Features

• Capacitance & Voltage: 2,200 µF (±20%) rated at 25 V — provides substantial bulk capacitance for filtering and energy reserve in audio power stages.
• Audio-Optimized Electrolyte: Part of the UKW series engineered for audio equipment, developed to support a harmonious balance of sound quality as noted in the series datasheet.
• Ripple Current Performance: Low-frequency ripple current 1.55 A (120 Hz) and high-frequency ripple current 1.7825 A (10 kHz) — supports AC ripple handling across audio-relevant frequency bands.
• Loss Characteristics: Tangent of loss angle (tan δ) = 0.18 measured at 20 °C, 120 Hz — useful for assessing dielectric losses in audio circuits.
• Endurance & Temperature Range: Rated for 2,000 hours at 85 °C and an operating range of −40 °C to +85 °C, providing defined life expectations under elevated-temperature operation.
• Mechanical & Mounting: Radial lead, polarized can package with dimensions φ12.5 × 25 mm and 5 mm lead spacing (±0.5 mm) — suitable for through-hole assembly and hand or wave soldering processes; available in bulk or bag packing.
• Leakage Current: Specified leakage current 1,650 µA — important for bias and standby current budgeting in audio designs.
• RoHS Compliant: Meets RoHS requirements as stated in product data.

Typical Applications

• AV and Home Audio Equipment: Bulk smoothing and power reservoir for amplifiers and preamplifiers where the UKW series is specified for audio performance.
• Power Supply Filtering: Main smoothing and ripple reduction in low-voltage audio power supplies and regulator output stages.
• Signal Chain Support: Decoupling and energy buffering in audio processing circuits to stabilize supply rails and reduce modulation of audio signals.

Unique Advantages

• Substantial Bulk Capacity: 2,200 µF provides significant energy storage to support dynamic audio loads and reduce voltage sag under transient demand.
• Audio-Focused Formulation: UKW series electrolyte development targets sound-quality balance, making this part well-suited to AV and consumer audio applications.
• Measured Ripple Capability: Specified ripple current values at both 120 Hz and 10 kHz allow designers to quantify performance across low and higher audio-relevant frequencies.
• Defined Life Rating: 2,000 hours at 85 °C gives a clear endurance benchmark for thermal stress planning and reliability forecasts.
• Through-Hole, Serviceable Package: Radial-lead can with 5 mm lead spacing simplifies prototyping, repair, and replacement in board-level audio designs.
• Regulatory Compliance: RoHS compliance provides assurance for regulatory requirements in target markets.
