UKT1A470MDD

The UKT1A470MDD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKT series, engineered for audio and general-purpose electronics requiring stable filtering and decoupling across a wide temperature range. This compact, polarized capacitor delivers 47 µF capacitance at a 10 V rating with features tuned for audio equipment and demanding operating conditions.

Key electrical and mechanical attributes include low leakage, defined ripple current performance at low and high frequencies, a wide -55°C to 105°C operating range, and 1000 hours endurance at 105°C. Note: this part is listed as End Of Life.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with ±20% tolerance and a 10 V rated voltage for power decoupling and coupling in low-voltage circuits.
• Temperature Range — Rated for operation from -55°C to 105°C, suitable for wide‑temperature applications in audio equipment.
• Endurance — 1000 hours life rating at 105°C, with capacitance and leakage within specified limits after the endurance test.
• Low Leakage Current — Specified leakage current of 14.1 µA, supporting lower standby loss and reduced bias drift in sensitive circuits.
• Ripple Performance — 68 mA ripple current at 120 Hz (low frequency) and 136 mA at 10 kHz (high frequency) for reliable filtering under varying ripple spectra.
• Compact Radial Package — φ5 × 11 mm can with 2 mm lead spacing in a radial-lead configuration for through-hole mounting and compact PCB layouts.
• AEC-Q200 Qualified — Series qualification indicated for enhanced reliability expectations in demanding applications.
• RoHS Compliance — UKT series is compliant with RoHS directives as noted for the series.
• Packing — Supplied in bulk (no terminal forming) / bag packing for high-volume assembly or manual handling.

Typical Applications

• Audio Equipment — Power-supply filtering, decoupling and signal-path coupling in amplifiers and audio subsystems where low leakage and wide temperature tolerance matter.
• Portable Audio Devices — Compact radial can and low-voltage rating make this capacitor suitable for space‑constrained, battery-powered audio circuitry.
• Analog Front-Ends — Use for decoupling and stabilization in analog stages where controlled leakage and ripple handling improve overall signal fidelity.

Unique Advantages

• Wide operating temperature span — -55°C to 105°C rating supports deployment across harsh and variable environments.
• Verified endurance at elevated temperature — 1000 hours at 105°C provides predictable long-term behavior for thermal-stressed designs.
• Low leakage for cleaner biasing — 14.1 µA leakage helps minimize offset and noise contribution in sensitive audio circuits.
• Frequency-aware ripple capability — Specified ripple currents for both low (120 Hz) and high (10 kHz) frequencies enable effective filtering across common noise spectra.
• Small footprint, through-hole convenience — φ5 × 11 mm radial can with 2 mm lead spacing eases replacement and assembly in compact board designs.
• Series-level compliance and reliability — UKT series compliance to RoHS and AEC-Q200 qualification supports selection for reliability-focused projects.
