UHD1A332MHD

The UHD1A332MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can, rated 3300 µF at 10 V. It is part of Nichicon’s UHD series engineered for lower impedance at higher frequencies and elevated ripple handling in a compact φ12.5 × 25 mm package.

Designed for general-purpose electronic designs, this radial-lead capacitor delivers specified ripple performance and long endurance for applications requiring stable capacitance and controlled leakage across –40 °C to 105 °C.

Key Features

• Electrical Performance — 3300 µF capacitance at 10 V with tolerance of −20% to +20% and a measured dissipation factor (tanδ) of 0.23 (20 °C, 120 Hz), providing quantifiable AC loss characteristics for design validation.
• Ripple Current Capability — Low-frequency ripple current of 2.216 A (120 Hz) and high-frequency ripple current of 2.77 A (100 kHz), supporting effective smoothing and decoupling where ripple handling is required.
• Leakage and Stability — Rated leakage current of 330 µA helps define standby and bias losses for power-sensitive designs.
• Reliability and Lifetime — Endurance specified at 5000 hours at 105 °C, enabling predictable long-term performance under elevated operating temperature.
• Compact Radial Package — φ12.5 × 25 mm can with 5 mm lead spacing (±0.5 mm) and radial-lead mounting simplifies through-hole assembly and layout planning.
• Environmental Compliance & Packaging — RoHS compliant and available in bulk (no terminal forming) or bag packing; part is in mass production.

Typical Applications

• General-purpose Power Electronics — Provides bulk energy storage and smoothing where a 10 V, 3300 µF capacitor is required in compact, through-hole form.
• Power Supply Filtering — Handles low- and high-frequency ripple currents to assist in voltage regulation and decoupling tasks in power rails.
• Industrial and Embedded Systems — Suited for designs operating across –40 °C to 105 °C that require long endurance and defined leakage for system stability.

Unique Advantages

• High ripple handling in a small footprint: Rated ripple currents of 2.216 A (120 Hz) and 2.77 A (100 kHz) are delivered from a φ12.5 × 25 mm can, enabling compact board layouts without sacrificing ripple performance.
• Quantified AC loss and leakage data: Specified tanδ (0.23 at 20 °C, 120 Hz) and leakage current (330 µA) provide measurable parameters for power-loss and thermal budgeting.
• Long endurance at elevated temperature: 5000 hours at 105 °C gives predictable life performance for designs exposed to sustained elevated operating temperatures.
• Radial-lead convenience: 5 mm lead spacing and standard radial can package simplify through-hole assembly and mechanical mounting.
• RoHS compliant and production-ready: Environmentally compliant and available in bulk or bag packing with mass-production status for supply continuity.
