UKA1V222MHD

The UKA1V222MHD is an aluminum electrolytic capacitor from Nichicon’s UKA series, engineered for high‑grade audio equipment. It delivers 2.2 mF (2200 µF) capacitance at a 35 V rating in a radial‑lead can optimized for through‑hole assemblies.

Designed for demanding audio applications, the device combines high capacitance, a wide operating temperature range (−55 °C to +105 °C) and a 2000‑hour endurance at 105 °C to provide stable energy storage and ripple handling in professional audio power systems.

Key Features

• Core Electrical — 2.2 mF (2200 µF) capacitance with ±20% tolerance (measured at 120 Hz, 20 °C) and a 35 V rated voltage for bulk energy storage in audio power rails.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) of 0.18 (measured at 120 Hz, 20 °C). Specified leakage current: 2310 µA after 1 minute and 770 µA after 2 minutes at 20 °C.
• Ripple Performance — Rated ripple current 1.26 A (1260 mArms) at 105 °C / 120 Hz and 1.449 A at 10 kHz, supporting sustained ripple handling in audio power supplies.
• Reliability & Lifetime — Operating temperature −55 °C to +105 °C with endurance specified as 2000 hours at 105 °C, enabling long service life under elevated thermal stress.
• Mechanical & Packaging — Compact φ12.5 × 40 mm can with radial lead spacing 5.0 mm (±0.5 mm). Supplied in bulk (no terminal forming) / bag packing; part is in mass production.
• Qualification — AEC‑Q200 listed in the provided specifications for designs requiring that qualification level.

Typical Applications

• High‑grade audio equipment — Bulk energy storage and smoothing for power supplies in professional amplifiers and studio gear where stable supply rails are required.
• Audio power supplies and regulators — Ripple suppression and decoupling on 35 V rails, leveraging the part’s rated ripple current and wide temperature endurance.
• Signal chain support in audio systems — Polarized decoupling and reservoir functions where large capacitance and controlled loss characteristics are needed.

Unique Advantages

• High capacitance in a compact can — 2200 µF in a φ12.5 × 40 mm radial package reduces board area while delivering substantial energy storage.
• Wide operating temperature and proven endurance — −55 °C to +105 °C rating with 2000 hours at 105 °C supports robust operation in thermally challenging audio equipment.
• Audio‑oriented electrical profile — Low tan δ and substantial ripple current capability (1.26 A at 120 Hz, 1.449 A at 10 kHz) align with the demands of high‑grade audio power systems.
• Manufacturing‑friendly packaging — Radial lead format with defined lead spacing and bulk/bag packing simplifies through‑hole assembly and inventory handling.
• Qualified reliability — Inclusion of AEC‑Q200 in the part’s specification provides an added level of qualification for designs that reference that standard.
