UKA1V470MDD

The UKA1V470MDD is a radial-lead aluminum electrolytic capacitor with a nominal capacitance of 47 µF and a rated voltage of 35 V. It is designed for audio applications and for operation across a wide temperature range from −55°C to 105°C.

This compact, polarized can (φ5 × 11 mm) delivers low dissipation (tanδ 0.16 at 20°C, 120 Hz), defined leakage current, and specified ripple current performance for both low- and high-frequency conditions, with an endurance rating of 2000 hours at 105°C.

Key Features

• Electrical Performance — 47 µF capacitance with tolerance −20% to +20% and a rated voltage of 35 V.
• Loss and Leakage — Dissipation factor (tanδ) of 0.16 measured at 20°C, 120 Hz, and a measured leakage current of 49.35 µA.
• Ripple Current Capability — Low-frequency ripple current 93 mA (120 Hz) and high-frequency ripple current 186 mA (10 kHz), supporting both power-supply smoothing and higher-frequency decoupling needs.
• Temperature and Endurance — Operating range −55°C to 105°C with an endurance specification of 2000 hours at 105°C.
• Package & Mounting — Radial lead, can-style package sized φ5 × 11 mm with 2.0 mm lead spacing (±0.5 mm); available bulk (no terminal forming) or bag packing.
• Reliability Rating — Series-level rating includes AEC-Q200.
• Polarized — Designed for polarized circuit placements typical of electrolytic capacitor use.

Typical Applications

• High‑grade audio equipment — Suited for use in audio components where stable capacitance, low loss, and wide temperature tolerance are required.
• Audio power-supply smoothing — Provides DC filtering and energy buffering in audio power rails.
• Decoupling and coupling in audio circuits — Used where polarized electrolytic capacitance is required for signal or power decoupling in audio designs.

Unique Advantages

• Compact through-hole form-factor — φ5 × 11 mm radial can delivers electrolytic capacitance in a small footprint for dense PCB layouts.
• Wide operating temperature — −55°C to 105°C rating supports designs that encounter extreme ambient conditions.
• Defined endurance — 2000 hours at 105°C provides a measurable lifecycle expectation for thermal stress environments.
• Frequency-aware ripple performance — Specified ripple currents at both 120 Hz and 10 kHz let designers account for low- and high-frequency stress when sizing capacitors.
• Series-level AEC-Q200 rating — Indicates additional reliability screening at the series level for demanding applications.

Why Choose UKA1V470MDD?

UKA1V470MDD combines a compact radial-can package with audio-focused electrical characteristics: a 47 µF capacitance at 35 V, low dissipation (tanδ 0.16 at 20°C/120 Hz), controlled leakage, and specified ripple current at both low and high frequencies. Its wide −55°C to 105°C temperature range and 2000-hour endurance at 105°C make it suitable for designs that require predictable performance under thermal stress.

This capacitor is well suited for engineers and procurement teams building audio equipment and related electronics who need a verified, through-hole aluminum electrolytic solution with explicit specifications for loss, leakage, ripple, and lifetime.
