UVY2A332MRD

The UVY2A332MRD is a high-capacitance, radial-lead aluminum electrolytic capacitor from Nichicon's UVY series. It provides 3300 µF of capacitance at a 100 V rating in a compact φ25 × 50 mm can, designed for general-purpose power applications that require bulk energy storage and smoothing.

Engineered for wide operating conditions, this polarized capacitor supports a temperature range from −55 °C to +105 °C and a rated endurance of 2000 hours at 105 °C, delivering stable performance in demanding thermal environments.

Key Features

• High Capacitance, High Voltage — 3300 µF at 100 V provides substantial bulk energy storage for mid-voltage rails and DC-link smoothing.
• Radial Lead Package — Standard radial-can construction (φ25 × 50 mm) with 12.5 mm lead spacing (±0.5 mm) for through-hole assembly and secure board mounting.
• Wide Temperature Range — Rated for −55 °C to +105 °C to support extended operation across harsh ambient and enclosure conditions.
• Endurance at Elevated Temperature — 2000 hours of rated life at 105 °C, enabling sustained performance where high-temperature reliability is required.
• Low-Frequency and High-Frequency Ripple Handling — Low-frequency ripple current of 2.070 A (120 Hz) and high-frequency ripple current of 2.3805 A (10 kHz) for effective ripple attenuation across frequencies common in power electronics.
• Electrical Loss and Leakage — tanδ of 0.08 (measured at 20 °C, 120 Hz) and a specified leakage current of 9,900 µA, allowing designers to account for dissipation and standby currents in system budgets.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit production and handling preferences.
• RoHS Compliant — Conforms to RoHS requirements for lead-free applications.

Typical Applications

• Power Supply Bulk Smoothing — Provides bulk capacitance on 100 V rails to reduce ripple and maintain stable DC output in industrial and commercial power supplies.
• DC-Link / Energy Storage — Serves as a DC-link or intermediate energy storage capacitor in converters and inverters where 100 V rating and multi-amp ripple capability are required.
• Hold-Up and Backup Circuits — Supports temporary energy hold-up in systems needing short-duration backup or ride-through capability, leveraging high capacitance and rated voltage.
• General Electronic Equipment — Fits general-purpose applications that demand reliable electrolytic bulk capacitance across a wide temperature range and extended life.

Unique Advantages

• Substantial Energy Density: 3300 µF at 100 V gives designers significant capacitance in a single radial-can package, reducing the need for multiple components.
• Designed for Elevated Temperatures: Rated for continuous operation up to 105 °C with a 2000-hour endurance rating, supporting designs with high thermal stress.
• Broad Ripple Performance: Specified ripple current values at both low and high frequencies allow predictable thermal and lifetime calculations across switching and line-frequency domains.
• Predictable Electrical Characteristics: Low tanδ (0.08 at 20 °C, 120 Hz) and a defined leakage current enable accurate loss and standby current planning in system designs.
• Standard Through-Hole Form Factor: Radial lead spacing and can dimensions simplify replacement and mechanical integration in established PCB layouts.
• RoHS Compliance: Meets RoHS requirements for lead-free manufacturing and regulatory conformity.
