UKL1V221KPD

The UKL1V221KPD is an aluminum electrolytic capacitor in a radial-lead can, specified for 220 µF capacitance at 35 V with a ±10% tolerance. It is tailored for audio applications where low leakage and reliable ripple handling are important.

Key electrical characteristics include low leakage current (15.4 µA), ripple current ratings of 440 mA at 120 Hz and 660 mA at 10 kHz, and an endurance rating of 2000 hours at 85 °C. Status: End Of Life; the series documentation notes the product is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Capacitance & Tolerance — 220 µF nominal capacitance with ±10% tolerance, suitable where precise bulk capacitance is required.
• Rated Voltage — 35 V rating for mid-voltage audio and related circuits.
• Low Leakage Current — Specified leakage of 15.4 µA, enabling stable bias conditions in sensitive circuits.
• Ripple Current Performance — 440 mA at 120 Hz and 660 mA at 10 kHz, supporting both low- and high-frequency ripple environments.
• Endurance & Temperature Range — Life rating of 2000 hours at 85 °C and operating range of −40 °C to 85 °C for sustained performance in typical audio equipment conditions.
• Package & Mounting — Radial lead can, size φ10 × 20 mm with 5 mm lead spacing (±0.5 mm), available in bulk or bag packing.
• RoHS Compliance — Compliant with RoHS requirements.
• Polarized — Designed for polarized circuit implementations.

Typical Applications

• Audio electronics — Specified for audio applications and suitable where low leakage and defined ripple handling improve signal and power stability.
• Audio power rails — Ripple current ratings (440 mA @120 Hz, 660 mA @10 kHz) make this part suitable for smoothing and filtering on audio power supply rails.
• Compact consumer audio devices — The φ10 × 20 mm radial can and 5 mm lead spacing fit compact PCB layouts in consumer audio products.

Unique Advantages

• Low leakage for stable biasing: 15.4 µA leakage current helps maintain predictable operating points in audio circuits.
• Broad ripple handling: Dual ripple ratings at 120 Hz and 10 kHz provide quantifiable performance for both low- and high-frequency ripple environments.
• Proven endurance: 2000 hours at 85 °C offers a measurable life expectation for sustained thermal conditions.
• Compact radial form factor: φ10 × 20 mm can with 5 mm lead spacing balances capacitance with space-constrained board designs.
• RoHS compliant: Meets environmental compliance requirements for restricted substances.

Why Choose UKL1V221KPD?

UKL1V221KPD delivers a focused set of electrical and mechanical characteristics—220 µF at 35 V, low leakage, defined ripple-current performance, and a compact radial package—that align with the needs of audio-focused designs requiring reliable smoothing and decoupling. Its endurance rating and operating temperature range provide a clear specification for designers targeting stable performance over time.

While this part provides measurable benefits for existing designs, note the product status is End Of Life and the series documentation indicates it is scheduled for discontinuation and not recommended for new designs. It remains a well-specified option for legacy maintenance or replacement where the listed characteristics are required.
