UKA1V221MPD

The UKA1V221MPD is a radial‑lead aluminum electrolytic capacitor designed for audio applications that require stable capacitance and extended temperature performance. It delivers 220 µF at 35 V with a ±20% tolerance in a compact φ8 × 11.5 mm can and 3.5 mm lead spacing.

Engineered for durability and audio‑grade performance, this component combines low loss (tanδ 0.16 at 20°C, 120 Hz), defined ripple handling, and long endurance (2000 hours at 105°C) for use in equipment operating across –55°C to 105°C.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 35 V with ±20% tolerance for predictable energy storage and decoupling in circuit designs.
• Low Loss — tanδ = 0.16 (measured at 20°C, 120 Hz), supporting lower dissipation in audio frequency applications.
• Ripple Current Capability — Rated low‑frequency ripple current 260 mA at 120 Hz and high‑frequency ripple current 390 mA at 10 kHz, enabling reliable ripple handling across common audio and supply frequencies.
• Leakage Current — Specified leakage current 231 µA for stable bias behavior after voltage application.
• Wide Temperature & Endurance — Operating range –55°C to 105°C with 2000 hours endurance at 105°C, suitable for prolonged operation in demanding thermal environments.
• Form Factor & Mounting — Radial lead, can package sized φ8 × 11.5 mm with 3.5 mm lead spacing, available in bulk or bag packing for through‑hole assembly.
• AEC‑Q200 Rating — Listed with an AEC‑Q200 rating, indicating compliance with the specified qualification entry present in the product data.

Typical Applications

• High‑grade audio equipment — Suited for power supply filtering and energy storage in audio circuits where low loss and stable capacitance are required.
• Audio electronics modules — Useful in amplifier and preamplifier boards that operate across wide temperature ranges and demand long endurance.
• Embedded power sections — Applicable for local decoupling and smoothing in through‑hole assemblies where a compact radial can is preferred.

Unique Advantages

• Audio‑oriented electrical profile: Low tanδ and specified ripple currents support cleaner power delivery and reduced dissipation in audio frequency ranges.
• Wide operating temperature: –55°C to 105°C rating enables use in environments with large thermal swings while maintaining performance.
• Long endurance at elevated temperature: 2000 hours at 105°C provides predictable ageing characteristics for lifespan planning.
• Compact through‑hole package: φ8 × 11.5 mm can with 3.5 mm lead spacing fits space‑constrained boards requiring radial mounting.
• Qualification noted in product data: AEC‑Q200 listing supports designs that reference recognized component qualification standards.
