UKL1H2R2MDD

The UKL1H2R2MDD is a miniature aluminum electrolytic capacitor in Nichicon's UKL series, offered in a radial lead can package. It provides 2.2 µF capacitance at a 50 V rating with a compact footprint (φ5 × 11 mm) and 2.0 mm lead spacing, designed for space-constrained electronic assemblies.

Targeted for audio and other small-signal applications, this capacitor emphasizes low leakage and stable performance across a –40 °C to 85 °C operating range, with an endurance rating of 2000 hours at 85 °C.

Key Features

• Capacitance & Voltage: 2.2 µF nominal capacitance with a 50 V rated voltage and tolerance of −20% to +20% for predictable charge storage in compact designs.
• Low Leakage Characteristic: Part of Nichicon's low leakage current family; specified leakage current of 0.22 µA at 20 °C for minimized standby loss and signal integrity.
• Loss Tangent (tan δ): tanδ = 0.08 measured at 20 °C, 120 Hz and 50 V, supporting low dissipation in audio and precision analog circuits.
• Ripple Current Performance: Rated low-frequency ripple current of 23 mA at 120 Hz and high-frequency ripple current of 46 mA at 10 kHz for moderate ripple handling in power filtering roles.
• Endurance & Temperature Range: Life specification of 2000 hours at 85 °C and an operating temperature range of −40 °C to 85 °C for reliable performance in typical consumer and industrial environments.
• Package & Mounting: Radial lead (can) construction with φ5 × 11 mm dimensions and 2.0 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for flexible assembly workflows.
• RoHS Compliant: Meets RoHS requirements for use in lead-restricted assemblies.

Typical Applications

• Audio equipment — Suited for audio circuitry where a compact, low-leakage capacitor is required for small-signal and filtering functions.

Unique Advantages

• Compact footprint: φ5 × 11 mm can size enables use in densely packed PCBs and small enclosures.
• Low leakage: 0.22 µA leakage current characteristic helps preserve bias conditions and reduces quiescent losses in sensitive circuits.
• Low dissipation: tanδ of 0.08 at 120 Hz supports lower heat generation and improved audio fidelity in signal paths.
• Balanced ripple capability: Defined low- and high-frequency ripple current ratings (23 mA at 120 Hz; 46 mA at 10 kHz) provide clear guidance for filter and decoupling design margins.
• Durability over temperature: 2000-hour endurance at 85 °C and a −40 °C to 85 °C operating range ensure predictable life and behavior across common environmental conditions.
• Radial lead convenience: Through-hole radial leads and standard lead spacing simplify prototyping and legacy-board integration.
