UKW2A222MRD

The UKW2A222MRD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKW series designed for audio equipment. It provides a high-voltage, high-capacitance solution in a compact can package, optimized for applications that require bulk energy storage and robust ripple current handling.

Key characteristics include 2200 µF capacitance at 100 V, a wide operating temperature range from −40°C to +85°C, and endurance specified for 2000 hours at 85°C — attributes that support reliable performance in audio power circuits.

Key Features

• Capacitance and Voltage — 2200 µF (2.2 mF) nominal capacitance with a rated voltage of 100 V and tolerance of −20% to +20% for predictable energy storage.
• Low-Frequency and High-Frequency Ripple Handling — Rated low-frequency ripple current 2.4 A at 120 Hz and high-frequency ripple current 2.76 A at 10 kHz, supporting power-supply smoothing and decoupling in audio systems.
• Measured Dissipation Factor — tanδ = 0.1 measured at 20°C, 120 Hz, enabling designers to evaluate AC loss performance under typical audio-band conditions.
• Leakage and Endurance — Specified leakage current 6600 µA and endurance of 2000 hours at 85°C with recovery to specified limits after the endurance test, supporting long-term stability in powered applications.
• Mechanical Profile — Compact radial can size φ22 × 50 mm (D × L) with 10 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for through-hole, radial-lead assembly.
• Temperature Range and Compliance — Operational from −40°C to +85°C and RoHS compliant for environmental regulatory alignment.

Typical Applications

• Audio Equipment — Suited for power-supply smoothing, rail decoupling, and energy storage in amplifiers and AV components where 100 V rating and 2200 µF capacitance are required.
• AV Systems — Use in audio-visual power circuits that need sustained ripple-current capability and thermal endurance at elevated operating temperatures.
• Power Filtering in Sound Electronics — Ideal for bulk filtering stages where both low- and high-frequency ripple handling support clean audio power delivery.

Unique Advantages

• High Voltage Capability: 100 V rated voltage enables use in higher-voltage audio power rails and provides design margin for demanding supply topologies.
• Substantial Energy Storage: 2200 µF capacitance supplies significant bulk charge capacity for smoothing and transient support in audio power stages.
• Robust Ripple Performance: Defined low- and high-frequency ripple current ratings (2.4 A @120 Hz, 2.76 A @10 kHz) allow predictable thermal and ripple management in power designs.
• Thermal Endurance: 2000 h rating at 85°C gives a quantifiable endurance metric for lifetime planning in continuous-duty audio environments.
• Compact Radial Form Factor: φ22 × 50 mm can with 10 mm lead spacing supports through-hole assembly and easy integration into existing PCB layouts.
• RoHS Compliant: Meets RoHS requirements for environmental conformity in commercial electronics production.
