UKT1H331MPD

The UKT1H331MPD is a radial-lead aluminum electrolytic capacitor in Nichicon's UKT series, specified at 330 µF and 50 V. It is designed for general audio equipment and other applications that require wide temperature operation, reliable endurance, and compact radial-can packaging.

Key value propositions include a wide operating temperature range from −55°C to 105°C, a 1000-hour endurance rating at 105°C, and AEC-Q200 qualification together with RoHS compliance at the series level, offering traceable reliability for demanding electronic designs.

Key Features

• Capacitance & Voltage — Rated capacitance 330 µF with tolerance −20% to +20%, and rated voltage 50 V for bulk energy storage and decoupling in power rails.
• Temperature and Endurance — Operates from −55°C to 105°C with a specified endurance of 1000 hours at 105°C, meeting the UKT series endurance criteria when restored to 20°C after test.
• Ripple Performance — Low-frequency ripple current 410 mA at 120 Hz and high-frequency ripple current 615 mA at 10 kHz, supporting filtering across audio and higher-frequency power circuits.
• Electrical Losses & Leakage — Tangent of loss angle (tanδ) 0.14 measured at 20°C and 120 Hz; leakage current specified at 495 µA for this part number.
• Package & Mounting — Radial-can construction (φ10 × 16 mm) with 5.0 mm lead spacing (±0.5 mm); lead diameter per series dimensional data is typically φ0.6 mm for the 10 mm case.
• Compliance & Qualification — Part of the UKT series which is compliant with the RoHS directive and AEC-Q200 qualified; the part is listed as in mass production.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to support different assembly and stocking workflows.

Typical Applications

• Audio Equipment — Intended for general audio applications where stable capacitance, low loss (tanδ), and reliable ripple handling are required for power supply filtering and decoupling.
• Embedded Power Rails — Compact radial can suited for smoothing and bulk storage on 50 V rails in compact boards and modules.
• Industrial Electronics — Wide −55°C to 105°C temperature range and 1000-hour endurance at 105°C make it applicable for equipment exposed to wide thermal environments.

Unique Advantages

• Wide Temperature Capability: −55°C to 105°C rating supports designs that experience wide ambient ranges without sacrificing capacitor performance.
• Proven Endurance: 1000-hour rated life at 105°C provides a clear reliability baseline for thermal-stressed and continuously powered systems.
• Measured Ripple Ratings: Specified ripple currents at both low and high frequencies (410 mA at 120 Hz, 615 mA at 10 kHz) allow designers to size bulk and decoupling capacitors against actual ripple loads.
• Low Dissipation Factor: tanδ of 0.14 at 20°C/120 Hz helps minimize heat generation and loss in audio and power applications.
• Compact Radial Form Factor: φ10 × 16 mm can size into space-constrained boards while providing significant capacitance for its footprint.
• Series-Level Compliance: UKT series RoHS compliance and AEC-Q200 qualification support regulatory and reliability requirements for many professional designs.
