UKL1V221MPD

The UKL1V221MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKL series, offering 220 µF capacitance at a 35 V rating with polarized radial can package (φ10×20 mm). It is designed for audio applications that benefit from low leakage current and defined ripple-handling capability.

This part features low dielectric loss (tanδ 0.12 at 20 °C, 120 Hz), specified ripple current performance up to 660 mA at high frequency, and an endurance rating of 2000 hours at 85 °C. Note: this part is End Of Life—availability and lead times should be confirmed before specification.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance with a rated voltage of 35 V; capacitance tolerance −20% to +20%.
• Low Leakage Performance — Classified in Nichicon’s low leakage current UKL series; leakage current specified at 15.4 µA for this part.
• Low Loss (tanδ) — Tangent of loss angle 0.12 (measured at 20 °C, 120 Hz), supporting low dissipation in audio signal environments.
• Ripple Current Capability — Rated low-frequency ripple current 440 mA (120 Hz) and high-frequency ripple current 660 mA (10 kHz), enabling stable performance with varying ripple spectra.
• Endurance and Temperature Range — Life/endurance 2000 hours at 85 °C with an operating range from −40 °C to 85 °C.
• Radial Can Package — Compact φ10×20 mm aluminum can with 5 mm lead spacing (±0.5 mm); supplied Bulk (no terminal forming) or Bag packed.
• RoHS Compliant — Meets RoHS requirements as indicated in product data.

Typical Applications

• Audio Equipment — Intended for audio applications where a 220 µF, 35 V polarized electrolytic with low leakage is required.
• Audio Power Supplies — Applicable where defined ripple current capability and low tanδ help maintain supply stability in audio systems.
• Consumer and Professional Audio Devices — Suited to space-constrained radial-lead implementations at φ10×20 mm footprint with 5 mm lead spacing.

Unique Advantages

• Low Leakage Design: Reduced leakage current (15.4 µA) supports long-term bias stability and minimizes standby losses in sensitive audio circuits.
• Defined Low Loss: tanδ of 0.12 at 20 °C/120 Hz reduces dissipation and helps maintain audio fidelity where dielectric losses matter.
• Frequency-Resilient Ripple Handling: Specified ripple currents of 440 mA (120 Hz) and 660 mA (10 kHz) provide predictable behavior across common ripple spectra.
• Compact Radial Form Factor: φ10×20 mm can with 5 mm lead spacing offers a compact, through-hole solution for retrofit or board-level designs.
• Endurance at Elevated Temperature: Rated for 2000 hours at 85 °C, supporting designs that require sustained operation at elevated temperatures.
• RoHS Compliance: Conforms to RoHS, simplifying environmental compliance for assemblies.

Why Choose UKL1V221MPD?

UKL1V221MPD is positioned for audio-focused designs that require a compact, radial aluminum electrolytic capacitor with low leakage, controlled dielectric loss, and defined ripple current performance up to 660 mA at higher frequencies. Its φ10×20 mm can and 5 mm lead spacing make it appropriate for board-level audio power and auxiliary circuits where a polarized bulk capacitance is needed.

Choose this part when you need verifiable specifications for leakage, tanδ, ripple current, and endurance in an RoHS-compliant radial package. Because the part is End Of Life, confirm availability and consider lifecycle implications for long-term production planning.
