UKA1C470MDD

The UKA1C470MDD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKA series, specified for audio applications. It delivers 47 µF capacitance at 16 V with ±20% tolerance in a compact φ5 × 11 mm can (1.1 × 0.5 cm).

Designed for equipment that requires wide temperature operation and reliable life under elevated temperature, this part offers a −55°C to 105°C operating range, 2000 hours endurance at 105°C, and rated ripple current characteristics for both low- and high-frequency use.

Key Features

• Capacitance & Voltage: 47 µF nominal capacitance with ±20% tolerance at a 16 V rated voltage.
• Ripple Current Performance: Rated ripple current of 79 mA at 120 Hz (low frequency) and 158 mA at 10 kHz (high frequency), suitable where AC ripple handling is required.
• Leakage Current: Specified leakage current of 22.56 µA, supporting predictable bias performance in audio circuits.
• Temperature & Endurance: Wide operating range from −55°C to 105°C and 2000 hours life/endurance at 105°C to support long-term stability in elevated-temperature environments.
• Package & Mounting: Radial lead, can-style package with 2 mm lead spacing and a compact φ5 × 11 mm footprint (1.1 × 0.5 cm overall).
• Qualification: Rated to AEC‑Q200, reflecting a defined qualification standard included in the product specification.

Typical Applications

• High‑grade audio equipment: Intended for audio systems where stable capacitance and endurance across a wide temperature range are required.
• Audio power modules: Use where controlled leakage and specified ripple current ratings support reliable power decoupling in audio circuitry.
• Audio component assemblies: Compact radial can and 2 mm lead spacing enable straightforward through‑hole mounting in modules and subassemblies for audio products.

Unique Advantages

• Wide operating temperature span: −55°C to 105°C supports designs that must perform across harsh thermal environments.
• Proven endurance at elevated temperature: 2000 hours at 105°C provides defined life expectations for long‑term reliability planning.
• Frequency‑aware ripple handling: Rated ripple currents specified for both 120 Hz and 10 kHz let designers assess performance across typical audio and high‑frequency conditions.
• Compact radial can: φ5 × 11 mm size with 2 mm lead spacing fits space‑constrained through‑hole PCB layouts.
• Traceable qualification: Inclusion of AEC‑Q200 in the ratings list provides an additional documented qualification standard in the product data.
