UKT1V331MPD

The UKT1V331MPD is a radial-leaded aluminum electrolytic capacitor from Nichicon’s UKT series, offering 330 µF capacitance at 35 V in a compact φ10 × 12.5 mm can with 5 mm lead spacing. Designed for general audio equipment and related electronics, it delivers a combination of wide operating temperature range and long-life endurance for reliable power decoupling and smoothing in demanding environments.

Key value propositions include low loss (tan δ = 0.16 at 20°C/120 Hz), rated ripple handling across low and high frequencies, AEC-Q200 qualification, and 1000-hour endurance at 105°C — attributes that support stable performance in temperature-variable and long-life applications.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 35 V with ±20% tolerance for predictable bulk energy storage and decoupling performance.
• Low Loss Performance — tan δ = 0.16 (max) measured at 20°C and 120 Hz, supporting efficient operation in audio and signal circuits.
• Ripple Current Capability — 350 mA at 120 Hz (low frequency) and 525 mA at 10 kHz (high frequency) for effective ripple absorption across a broad spectral range.
• Leakage Current — specified leakage current of 346.5 µA for predictable bias behavior after voltage application.
• Wide Temperature & Endurance — operating range −55°C to 105°C with 1000 hours life at 105°C to support extended duty in elevated-temperature environments.
• Radial Lead Package — φ10 × 12.5L can with 5 mm lead spacing, supplied in bag/bulk packaging for through-hole assembly and manual or wave processes.
• Manufacturing & Compliance — AEC-Q200 rating and RoHS compliance noted in the UKT series, and the part is in mass production status.

Typical Applications

• Audio Equipment — Designed for general audio equipment where stable capacitance, low loss, and endurance at 105°C contribute to clean power rails and consistent audio performance.
• Power Supply Filtering — Bulk decoupling and smoothing in power rails for amplifiers and signal-processing stages that require robust ripple handling.
• Industrial Electronics — Use in temperature-variable environments where long endurance and wide operating temperature range are required.

Unique Advantages

• Stable AC performance: Low tan δ (0.16 at 120 Hz) reduces dissipation in audio and signal paths for improved efficiency and thermal behavior.
• Broad ripple handling: Specified ripple currents at both low (120 Hz) and high (10 kHz) frequencies provide versatility across switching and linear power topologies.
• High-temperature endurance: 1000 hours at 105°C enables longer service life in elevated-temperature installations.
• Wide operating range: −55°C to 105°C supports deployments across harsh and variable ambient conditions.
• Automotive-grade reliability: AEC-Q200 qualification (as noted for the UKT series) underlines suitability for demanding reliability requirements.
• Compact, through-hole form factor: φ10 × 12.5 mm radial can with 5 mm lead spacing simplifies layout for discrete, serviceable designs.
