UHD0J332MHD

The UHD0J332MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHD series, engineered for general-purpose power applications that require high ripple handling and stable performance across a wide temperature range. It delivers 3,300 µF at 6.3 V in a compact φ12.5 × 20 mm can with polarized radial leads.

Designed for applications that demand low impedance at higher frequencies and long endurance, this capacitor is suitable for bulk smoothing, decoupling and hold-up roles in low-voltage power systems where robust ripple current capability and a small footprint matter.

Key Features

• High capacitance in compact can — 3,300 µF in a φ12.5 × 20 mm radial-can package provides bulk energy storage in a small footprint.
• Rated voltage — 6.3 V nominal voltage for low-voltage rail and power-supply applications.
• High ripple-current capability — Low-frequency ripple current of 1.888 A (120 Hz) and high-frequency ripple current of 2.36 A (100 kHz) to support rigorous switching and filtering loads.
• Lower impedance at high frequency — UHD series construction targets reduced impedance in the high-frequency band to improve decoupling and stability in switching circuits.
• Long endurance — Rated for 5,000 hours at 105 °C (φ12.5 case), delivering predictable life for sustained high-temperature operation.
• Wide operating temperature — −40 °C to +105 °C for applicability across varied thermal environments.
• Leakage current specification — Leakage after 2 minutes at 20 °C is ≤ 0.01CV, which for this part equates to approximately 207.9 µA.
• Capacitance tolerance — ±20% at 120 Hz, 20 °C for straightforward selection against design margins.
• Radial lead mounting — Polarized radial-lead construction with 5 mm lead spacing (±0.5 mm) for easy through-hole assembly and PCB placement.
• RoHS compliant — Conforms to RoHS directive requirements.
• Packaging options — Available in bulk (no terminal forming) or bag packing for flexible procurement and assembly workflows.

Typical Applications

• Power supplies — Bulk smoothing and output filtering for low-voltage DC power supplies where high ripple current and compact size are required.
• DC–DC converters — Input/output decoupling and energy storage for switching converters that generate high-frequency ripple currents.
• Embedded systems — Local rail stabilization and hold-up for microcontroller and peripheral power domains in compact assemblies.
• Communications and networking equipment — Power filtering and transient energy support in small form-factor networking modules and related electronics.

Unique Advantages

• High ripple handling in a small can: 1.888 A at 120 Hz and 2.36 A at 100 kHz deliver substantial ripple capability without a larger package.
• Improved high-frequency performance: Lower impedance at higher frequencies helps maintain voltage stability around switching components and reduces noise.
• Robust thermal endurance: Rated 5,000 hours at 105 °C for extended operation in warm environments and sustained loading conditions.
• Predictable leakage behavior: Specified leakage ≤ 0.01CV (≈207.9 µA) after 2 minutes at 20 °C enables reliable margining for low-voltage designs.
• Compact, assembly-friendly form: φ12.5 × 20 mm radial can with 5 mm lead spacing fits dense PCBs and through-hole manufacturing processes.
• Regulatory compliance: RoHS compliance supports environmental and procurement policies.
