UKL1H2R2KDD

The UKL1H2R2KDD is a Nichicon UKL series aluminum electrolytic capacitor designed for low leakage current in a radial lead, can-style package. It offers a capacitance of 2.2 µF at a rated voltage of 50 V and is targeted for audio applications where polarized electrolytic capacitors are specified.

This product is RoHS compliant. Note: the UKL series includes products that are scheduled to be discontinued and this part is not recommended for new designs.

Key Features

• Low Leakage Current (Series Performance) UKL is a standard low leakage current series; series leakage is specified as not more than 0.002CV (µA) after the prescribed application time in the datasheet.
• Electrical Ratings 2.2 µF capacitance at 50 V rated voltage with ±20% tolerance and polarized construction, suitable where a small-value aluminum electrolytic is required.
• Ripple Current Characteristics Rated ripple current of 23 mA at 120 Hz (low frequency) and 46 mA at 10 kHz (high frequency), supporting both mains-frequency and higher-frequency ripple conditions.
• Compact Radial Can Package Radial lead mounting with lead spacing of 2 mm and package dimensions L: 1.1 × D: 0.5 cm, enabling placement in tight board area footprints.
• Temperature and Lifetime Operating temperature range of –40 °C to 85 °C with a specified lifetime of 2000 hours at 85 °C.
• Regulatory Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — For use in audio circuits and components where a low-leakage, polarized aluminum electrolytic capacitor is required.
• Consumer Electronics Maintenance — Replacement or service parts for existing assemblies that specify a compact radial aluminum electrolytic capacitor.
• General Purpose Electronics — Where a compact 2.2 µF/50 V polarized capacitor with defined ripple characteristics and RoHS compliance is needed.

Unique Advantages

• Low Leakage Series Design: Built as part of Nichicon’s UKL low leakage family, providing leakage specifications that support signal-sensitive circuits.
• Measured Ripple Performance: Published ripple current values at both 120 Hz and 10 kHz (23 mA and 46 mA respectively) allow designers to assess suitability for specific ripple environments.
• Compact Radial Can Form Factor: Small footprint (L: 1.1 × D: 0.5 cm) and 2 mm lead spacing simplify placement in constrained board areas.
• Wide Operating Range: –40 °C to 85 °C operating range and 2000-hour lifetime at 85 °C support stable performance in typical commercial environments.
• RoHS Compliance: Meets RoHS directive requirements for restricted substances.

Why Choose UKL1H2R2KDD?

The UKL1H2R2KDD provides a compact, low-leakage aluminum electrolytic solution in a radial lead can, delivering clearly specified electrical and environmental characteristics—2.2 µF at 50 V, defined ripple current figures, and an operating range of –40 °C to 85 °C. It is suitable for designs and repairs that require a small polarized capacitor with measurable performance data and RoHS compliance.

Because this part is part of a series scheduled for discontinuation and is not recommended for new designs, it is particularly appropriate for maintenance, replacement, and legacy system support where matching existing component performance is required.
