UKT1H4R7MDD

The UKT1H4R7MDD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKT series, specified for general audio equipment and wide temperature operation. It delivers a 4.7 µF capacitance at a 50 V rating in a compact φ5 × 11 mm can with 2.0 mm lead spacing.

Designed for applications that require polarized electrolytic capacitance across a broad temperature range, this part offers a 1000-hour endurance at 105°C, AEC-Q200 qualification, and RoHS compliance for regulated designs.

Key Features

• Capacitance & Voltage — 4.7 µF capacitance rated at 50 V for polarized circuit requirements.
• Compact Radial Package — φ5 × 11 mm aluminum can with 2.0 mm lead spacing (±0.5 mm) for through-hole mounting in space-constrained assemblies.
• Wide Temperature Range — Operating temperature from −55°C to +105°C suitable for equipment requiring extended thermal range.
• Endurance — Rated for 1000 hours at 105°C with defined limits on capacitance change, tan δ, and leakage current after the endurance test.
• Loss and Leakage — Tangent of loss angle (tan δ) 0.14 (measured at 20°C, 120 Hz) and specified leakage current of 7.05 µA for this nominal value and voltage.
• Ripple Handling — Specified low-frequency ripple current of 30 mA at 120 Hz and high-frequency ripple current of 60 mA at 10 kHz for audio-frequency and higher-frequency ripple environments.
• Compliance & Qualification — RoHS-compliant and listed with AEC-Q200 to support reliability-focused designs.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit prototyping and production handling.

Typical Applications

• General Audio Equipment — Intended for use across general audio electronics where a compact, polarized electrolytic capacitor is required.
• Audio Power Filtering — Suitable for smoothing and ripple control in audio power supply sections within the specified ripple current limits.
• Audio Signal Circuitry — Use where a small, reliable polarized capacitor with a 50 V rating and wide temperature operation is needed in audio circuit layouts.

Unique Advantages

• Compact footprint: The φ5 × 11 mm can and 2.0 mm lead spacing enable placement in dense through-hole designs without sacrificing capacitance.
• Wide operating temperature: −55°C to +105°C rating supports designs exposed to varying environmental conditions while maintaining specified performance after 1000 hours at 105°C.
• Acoustically targeted series: Part of the UKT series developed for general audio equipment, aligning the component’s characteristics with audio design requirements.
• Measured electrical characteristics: Specified tan δ (0.14 at 120 Hz, 20°C) and defined leakage current provide verifiable parameters for design verification and qualification testing.
• Industry qualification: AEC-Q200 listing and RoHS compliance help streamline inclusion in reliability-focused and regulatory-compliant designs.
• Flexible handling: Bulk or bag packing options simplify procurement for both small runs and larger production batches.
