UKA1A103MHD

The UKA1A103MHD is a radial‑lead aluminum electrolytic capacitor from Nichicon’s UKA series, designed for high‑grade audio and related electronic equipment. This polarized, high‑capacitance component provides bulk energy storage and smoothing in power rails where wide temperature range and endurance are required.

Key attributes include 10000 µF nominal capacitance at 16 V, a wide operating temperature range of −55°C to 105°C, and a 2000‑hour endurance rating at 105°C—making it suitable for demanding audio and general power‑filtering applications.

Key Features

• High Capacitance (10000 µF): Provides substantial bulk energy storage for smoothing and decoupling in power supplies and audio circuits.
• Rated Voltage (16 V): Suitable for low‑voltage audio and electronic power rail applications that require robust filtering.
• Radial Lead, Can Package: φ16 × 35.5 mm can with 7.5 mm lead spacing for through‑hole mounting and straightforward assembly.
• Wide Temperature Range: Specified to operate from −55°C to 105°C to support equipment used across broad environmental conditions.
• Long Endurance: 2000 hours at 105°C endurance specification, with post‑test limits for capacitance change, tan δ and leakage current defined by the datasheet.
• High Ripple Current Capability: 1890 mA at 120 Hz (low frequency) and 2173.5 mA at 10 kHz (high frequency) to support transient and AC ripple demands on supply rails.
• Electrical Loss and Leakage: Specified tan δ of 0.44 (20°C, 120 Hz) and leakage current of 3000 µA, enabling designers to account for dissipation and self‑discharge in their power budgets.
• Quality Rating: AEC‑Q200 listed in the part data, indicating suitability for designs requiring established component qualification procedures.
• Packaging Options & Availability: Available in bulk (no terminal forming) and bag packing; part is indicated as mass production status from the manufacturer Nichicon.

Typical Applications

• High‑Grade Audio Equipment: Bulk filtering and energy storage in amplifier power supplies and preamplifier rails to support low‑frequency dynamics and stable operation.
• Power Supply Smoothing: DC rail smoothing and ripple suppression where high capacitance and elevated ripple current handling are needed.
• Electronic Equipment in Wide Temperature Environments: Systems requiring dependable capacitance across −55°C to 105°C operating range and long endurance at elevated temperature.

Unique Advantages

• Large Energy Density in a Compact Can: 10000 µF in a φ16 × 35.5 mm package minimizes board area while delivering significant bulk capacitance.
• Designed for Thermal and Long‑Term Stress: 2000‑hour endurance at 105°C gives designers a clear specification for life and reliability planning.
• High Ripple Handling Across Frequencies: Specified ripple current at both 120 Hz and 10 kHz supports a range of power‑supply and audio load conditions.
• AEC‑Q200 Listed: Conforms to established qualification expectations for components used in designs that track qualification protocols.
• Through‑Hole Radial Form Factor: Simplifies replacement, prototyping, and mechanical robustness in assemblies where leaded components are preferred.
• Production Ready: Mass production status and standard packaging options (bulk/bag) ease procurement and inventory planning.
