UVK2A222MRD

The UVK2A222MRD is a miniature, standard-type aluminum electrolytic capacitor from Nichicon’s UVK series. It is a radial-lead, polarized capacitor specified at 2200 µF and a rated voltage of 100 V, designed for general-purpose electronic applications.

Key electrical and mechanical characteristics include a -40 °C to 85 °C operating range, 2000 hours endurance at 85 °C, low- and high-frequency ripple current ratings, and RoHS compliance. Status: End Of Life.

Key Features

• Capacitance & Voltage: 2200 µF capacitance at a 100 V rated voltage provides bulk energy storage in a compact radial-can package.
• Electrical Loss Characteristics: Tangent of loss angle (tan δ) 0.1 measured at 20 °C, 120 Hz, supporting predictable AC performance.
• Ripple Current Capability: Low-frequency ripple current 2.4 A (120 Hz) and high-frequency ripple current 2.76 A (10 kHz), enabling handling of AC stress across frequency ranges.
• Leakage Current: Specified leakage current 6600 µA, defined under rated conditions for predictable standby and load behavior.
• Reliability and Lifetime: Endurance rating of 2000 hours at 85 °C with specified limits on capacitance change, tan δ, and leakage current after test.
• Compact Mechanical Package: Dimension φ22 × 50 mm with 10 mm lead spacing (±0.5 mm) in a radial can—available in bulk or bag packing for assembly flexibility.
• Environmental Compliance: Compliant to the RoHS directive as specified for the UVK series.

Typical Applications

• General-purpose electronic circuits — Suitable where a 2.2 mF, 100 V aluminum electrolytic capacitor in a radial package is required.
• Power supply modules — Applicable for smoothing and energy storage roles that match the capacitor’s rated voltage and ripple current ratings.
• Industrial and embedded systems — Use in designs operating across the specified −40 °C to 85 °C temperature range and requiring long-term endurance at elevated temperature.

Unique Advantages

• High voltage rating: 100 V nominal rating supports higher-voltage general-purpose designs without additional series stacking.
• Strong ripple handling: Rated ripple currents of 2.4 A (120 Hz) and 2.76 A (10 kHz) address both low- and high-frequency AC stress in circuits.
• Miniature radial can: φ22 × 50 mm footprint provides a smaller case size consistent with the UVK series’ miniature design intent.
• Defined long-term endurance: 2000-hour endurance at 85 °C with specified limits for capacitance, tan δ, and leakage current supports reliable life-cycle planning.
• RoHS compliant: Meets RoHS directive requirements as declared for the UVK series.
