UKA1H221MPD

The UKA1H221MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKA series designed for high-grade audio equipment. It combines a 220 µF capacitance with a 50 V rating, a wide operating temperature range, and documented endurance for robust performance in demanding environments.

Key value propositions include high ripple-current capability across low and high frequencies, low leakage current, and long-term endurance at elevated temperature—attributes suited to audio-focused designs that require stable power conditioning over time and temperature.

Key Features

• Capacitance & Voltage – 220 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance (at 120 Hz, 20°C).
• Ripple Current Performance – Supports 300 mA ripple current at 120 Hz (low frequency) and 450 mA at 10 kHz (high frequency), enabling handling of both low- and high-frequency ripple stress.
• Low Leakage – Specified leakage current of 330 µA for reduced standby losses and improved bias stability.
• Extended Temperature & Endurance – Operating range from −55°C to +105°C with a rated lifetime of 2000 hours at 105°C.
• Loss Angle (tan δ) – Low dissipation: tan δ max. 0.14 at 50 V (measured at 120 Hz, 20°C) per the series specification.
• Package & Mounting – Radial lead, can-style package (φ10 × 12.5 mm body) with 5 mm lead spacing; supplied in bulk/bag packing for production use.
• Qualification – Designed to UKA series standards and AEC-Q200 rated for component-level reliability expectations.

Typical Applications

• High-grade audio equipment – Suitable for audio equipment designs where stable capacitance, low leakage, and extended temperature endurance are required.
• Audio power modules – Appropriate for power conditioning roles within audio systems that demand both low- and high-frequency ripple handling.
• Temperature-sensitive audio assemblies – Designed to operate across −55°C to +105°C with a 2000-hour endurance at 105°C for reliable long-term performance in varied environments.

Unique Advantages

• Dual-frequency ripple capability – Rated ripple currents at 120 Hz and 10 kHz address ripple sources across the audio bandwidth, helping maintain supply stability under varied operating conditions.
• Long endurance at elevated temperature – 2000 hours at 105°C supports reliable life in designs exposed to sustained high temperatures.
• Wide operating temperature range – −55°C to +105°C operation provides design flexibility for both temperate and harsh environments.
• Low standby leakage – 330 µA leakage current minimizes idle losses and contributes to consistent biasing in audio circuits.
• Through-hole radial can package – φ10×12.5 mm can with 5 mm lead spacing simplifies replacement, prototyping, and mechanical mounting in conventional PCB layouts.
• AEC-Q200 qualification – Component-level quality assessment supports use where enhanced reliability expectations are required during design selection.
