UKL2A221KHD

The UKL2A221KHD is a radial-lead aluminum electrolytic capacitor with 220 µF capacitance and a 100 V rating. It combines a compact φ16 × 25 mm can with low leakage characteristics and specified ripple current performance to serve demanding electronic designs.

Targeted for audio and related electronics, this unit provides low leakage current, defined low- and high-frequency ripple current ratings, and a 2000 hour endurance at 85°C. Note: this product is End Of Life and is scheduled for discontinuation; it is not recommended for new designs.

Key Features

• Capacitance & Tolerance — 220 µF with ±10% tolerance (K) measured at 120 Hz, 20°C.
• Rated Voltage — 100 V DC rating suitable for high-voltage audio and power circuits.
• Low Leakage Current — Leakage current specified as 44 µA, beneficial where low self-discharge is needed.
• Ripple Current Capability — 580 mA at 120 Hz (low frequency) and 870 mA at 10 kHz (high frequency) to address both mains-frequency and high-frequency ripple conditions.
• Endurance — 2000 hours life at 85°C with rated voltage applied; performance restored to 20°C after test.
• Temperature Range — Operates from −40°C to +85°C.
• Package & Mounting — Radial lead can (φ16 × 25L) with 7.5 mm lead spacing and polarized construction; available in bulk (no terminal forming) or bag packing.
• Compliance — RoHS compliant.

Typical Applications

• Audio — Suited to audio electronics that require 220 µF capacitance at up to 100 V with low leakage and specified ripple current capability.
• General Power Electronics — Applicable where a radial-lead, polarized electrolytic capacitor with defined endurance and ripple specifications is required.
• Industrial Electronics — Useful in industrial designs operating across −40°C to +85°C that need a compact φ16 × 25 mm capacitor with moderate ripple handling.

Unique Advantages

• High Voltage Handling: 100 V rating provides headroom for higher-voltage circuits without changing package size.
• Low Leakage: Specified 44 µA leakage current supports designs sensitive to self-discharge and bias retention.
• Frequency-graded Ripple Performance: Separate ripple current ratings for 120 Hz (580 mA) and 10 kHz (870 mA) allow predictable behavior across low- and high-frequency conditions.
• Durability at Elevated Temperature: 2000 hours endurance at 85°C under rated voltage gives a defined lifecycle metric for thermal-stressed applications.
• Compact Radial Can: φ16 × 25 mm package with 7.5 mm lead spacing simplifies layout in through-hole and mixed-technology assemblies.
• RoHS Compliant: Meets regulatory requirements for restricted substances in many regions.

Why Choose UKL2A221KHD?

The UKL2A221KHD positions itself as a compact, low-leakage aluminum electrolytic solution for audio and general-purpose power applications that require a 220 µF capacitance at up to 100 V. Its clearly specified ripple currents at both low and high frequency, combined with a 2000 hour endurance at 85°C, deliver predictable performance for designs with defined thermal and ripple-load expectations.

This part is appropriate for engineers and procurement teams looking for a radial-lead electrolytic with documented leakage, ripple, and lifetime characteristics. Because the product is End Of Life and scheduled for discontinuation, it is best suited for replacement, support, or limited-quantity projects rather than new long-term designs.
