UKL1V222MHD

The UKL1V222MHD is an aluminum electrolytic capacitor from Nichicon’s UKL series designed for low leakage current in radial lead, through‑hole assemblies. It provides 2200 µF capacitance at a 35 V rated voltage and targets audio applications where high bulk capacitance, controlled leakage and robust ripple handling are required.

Key attributes include low leakage current, defined ripple current performance across low and high frequencies, and an endurance rating of 2000 hours at 85°C, making it suitable for equipment that requires stable capacitance and predictable behaviour under thermal stress.

Key Features

• Capacitance & Tolerance — 2200 µF nominal with ±20% tolerance, offering substantial bulk energy storage for smoothing and decoupling in audio circuits.
• Rated Voltage — 35 V working voltage for mid‑range power rails.
• Low Leakage Current — Specified leakage current of 154 µA, minimizing DC loss and drift in bias‑sensitive circuits.
• Ripple Current Performance — Low frequency ripple current 1.58 A (120 Hz) and high frequency ripple current 1.817 A (10 kHz), supporting demanding audio ripple and transient conditions.
• Endurance & Temperature Range — Life rating of 2000 hours at 85°C and operating temperature range of −40°C to +85°C for thermal reliability in typical audio environments.
• Radial Lead Package — φ18 × 35.5 mm can with 7.5 mm lead spacing (±0.5 mm) for straightforward through‑hole assembly and mechanical stability.
• Polarized — Designed as a polarized electrolytic component for DC applications that require polarity awareness.
• RoHS Compliant — Manufactured in compliance with RoHS requirements.
• Packaging Options — Available in Bulk (No Terminal Forming) and Bag Packing to suit production handling preferences.

Typical Applications

• Audio Power Supply Filtering — Bulk capacitance and measured ripple current ratings support smoothing of audio power rails where low leakage is important.
• Amplifier Decoupling — High capacitance and low leakage help maintain stable bias and reduce unwanted DC shifts in amplifier stages.
• Professional Audio Equipment — Radial lead form factor and compact φ18 × 35.5 mm package size simplify integration into through‑hole audio electronics and modules.

Unique Advantages

• High Bulk Storage: 2200 µF capacity provides significant energy reserve for load transients and smoothing in audio power rails.
• Low Self‑Discharge: 154 µA leakage current reduces DC offset and preserves stored charge where minimal leakage is required.
• Frequency‑Aware Ripple Capability: Specified ripple currents at both 120 Hz (1.58 A) and 10 kHz (1.817 A) give predictable performance across typical audio frequency ranges.
• Through‑Hole Robustness: Radial lead, can‑style package with 7.5 mm lead spacing supports reliable mechanical mounting and manual or wave soldering assembly processes.
• Defined Endurance: 2000 hours at 85°C provides a measurable lifetime metric for thermal stress planning and maintenance scheduling.
• Regulatory Compliance: RoHS compliance helps meet environmental requirements for electronics manufacturing.
