UKL1J221MHD

The UKL1J221MHD is a radial-lead aluminum electrolytic capacitor engineered for low leakage current applications. It delivers 220 µF capacitance at a 63 V rating in a compact φ12.5 × 20 mm can with 5 mm lead spacing.

Designed for audio and related electronics, the part offers specified ripple current performance at both low and high frequencies, a wide operating temperature range of -40°C to 85°C, and 2000 hours endurance at 85°C.

Key Features

• Capacitance & Voltage 220 µF nominal capacitance with ±20% tolerance and a rated voltage of 63 V.
• Low Leakage Current Specified leakage current of 27.72 µA (measured per product data), suitable where minimal DC loss is required.
• Frequency-Specific Ripple Performance Low-frequency ripple current: 550 mA at 120 Hz; high-frequency ripple current: 825 mA at 10 kHz, enabling defined ripple handling across common audio-related frequencies.
• Endurance & Temperature Range Rated for 2000 hours at 85°C and an operating range from -40°C to 85°C.
• Radial Lead Package Through-hole radial lead format in a φ12.5 × 20 mm can with 5 mm lead spacing and 0.5 mm lead spacing tolerance for mechanical predictability in assemblies.
• Polarized Polarized electrolytic design for DC smoothing and decoupling use cases.
• Compliance & Packaging RoHS compliant; available in bulk (no terminal forming) or bag packing options.

Typical Applications

• Audio systems — Suited for audio equipment where 220 µF at 63 V and low leakage are required for power supply smoothing and decoupling.
• Power filtering in electronics — Useful where defined ripple current ratings at 120 Hz and 10 kHz are needed to manage low- and high-frequency ripple components.
• Board-level through-hole assemblies — Radial lead configuration and compact φ12.5 × 20 mm size simplify placement in through-hole designs.

Unique Advantages

• Low leakage reduces standby current: Specified leakage of 27.72 µA minimizes DC loss in circuits requiring low quiescent drain.
• Defined ripple capability across frequencies: 550 mA at 120 Hz and 825 mA at 10 kHz provide predictable ripple-handling for mixed-frequency power rails.
• Compact radial-can form factor: φ12.5 × 20 mm size with 5 mm lead spacing balances capacitance with a small PCB footprint for through-hole layouts.
• Endurance at elevated temperature: Rated for 2000 hours at 85°C, enabling reliable service in sustained elevated-temperature conditions within the specified range.
• RoHS compliant: Meets RoHS requirements for environmental compliance in applicable assemblies.
• Packaging flexibility: Available in bulk (no terminal forming) or bag packing to suit production or prototyping workflows.
