UKL1H220MED

The UKL1H220MED is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKL series, engineered for low leakage performance in compact through-hole form. With a nominal capacitance of 22 µF and a 50 V rating, it is tailored for audio applications that demand low-loss behavior and stable electrical characteristics.

Key attributes include very low leakage current, a low dissipation factor measured at 20°C/120 Hz, and defined ripple current ratings for both low and high frequency conditions—making it a practical choice where controlled loss and compact packaging are required.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance (M) at 120 Hz, 20°C.
• Low Leakage & Dissipation — Specified leakage current of 2.2 µA and tanδ 0.08 (measured at 20°C, 120 Hz) to minimize standby loss and dissipation in signal paths.
• Ripple Current Capability — Low-frequency ripple current 110 mA at 120 Hz and high-frequency ripple current 220 mA at 10 kHz to handle varying ripple conditions.
• Package & Mounting — Radial can package, size φ6.3 × 11 mm, with 2.5 mm lead spacing (±0.5 mm), suitable for through-hole mounting in compact board layouts.
• Temperature & Endurance — Operating temperature range −40°C to +85°C with an endurance rating of 2000 hours at 85°C.
• Polarized Construction — Polarized aluminum electrolytic design for DC circuits.
• Regulatory — RoHS compliant.

Typical Applications

• Audio — Intended for audio applications where low leakage, low dissipation factor, and a compact radial-lead package are required.

Unique Advantages

• Reduced standby drain — Low leakage current (2.2 µA) helps minimize charge loss in sensitive circuits.
• Improved signal integrity — Low tanδ (0.08 at 20°C/120 Hz) supports lower loss in audio signal paths.
• Versatile ripple handling — Defined ripple current ratings at 120 Hz and 10 kHz provide predictable behavior across frequency ranges.
• Space-efficient through-hole form — φ6.3 × 11 mm can and 2.5 mm lead spacing enable compact board placement for legacy and repair applications.
• Rated endurance — 2000 hours at 85°C gives predictable performance under elevated-temperature operation.
• RoHS compliance — Conforms to restricted-substance requirements for environmental compliance.
