UVY1A333MRD

The UVY1A333MRD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UVY series, offering 33,000 µF capacitance at a 10 V rating. It is a standard-type, polar capacitor in a compact φ22 × 50 mm can with 10 mm lead spacing designed for general-purpose electronic applications that require substantial bulk capacitance in a through-hole package.

Key value propositions include wide operating temperature capability (−55 °C to +105 °C), a 2000-hour endurance rating at 105 °C, and defined ripple-current handling for both low- and high-frequency conditions—making it appropriate where long-term stability and ripple tolerance are required.

Key Features

• High Bulk Capacitance: 33,000 µF nominal capacitance with tolerance of −20% to +20%, providing substantial energy storage in a single component.
• Rated Voltage: 10 V DC nominal rating for low-voltage power systems and general-purpose circuits.
• Dissipation Factor (tan δ): tan δ = 0.88 measured at 20 °C, 120 Hz, consistent with large-capacitance characteristics.
• Ripple Current Capability: Low-frequency ripple current 3.21 A at 120 Hz and high-frequency ripple current 3.692 A at 10 kHz, supporting circuits with significant AC current components.
• Leakage Current: Specified leakage current of 9,900 µA (as provided in product data).
• Wide Temperature & Endurance: Operating temperature range −55 °C to +105 °C with endurance rated for 2000 hours at 105 °C.
• Package & Mounting: Radial-lead can package (φ22 × 50 mm) with 10 mm lead spacing and lead spacing tolerance ±0.5 mm for through-hole assembly.
• RoHS Compliant: Meets RoHS requirements as indicated in the product information.
• Series Note: UVY series offers one rank smaller case sizes than the UVZ series (as described in the datasheet).

Typical Applications

• General-purpose electronic circuits — Intended for designs that require a high-value, low-voltage electrolytic capacitor in a through-hole radial package.
• Power module bulk capacitance — Provides substantial bulk capacitance at 10 V for circuits needing energy storage in a compact can (φ22 × 50 mm).
• Environments with wide temperature ranges — Suited to applications that must operate between −55 °C and +105 °C with specified endurance at elevated temperature.
• Circuits with AC ripple — Specified low- and high-frequency ripple current ratings support use in circuits where ripple handling is a design consideration.

Unique Advantages

• Large capacitance in a compact radial can: 33,000 µF in a φ22 × 50 mm package delivers high bulk capacitance while maintaining a standard radial-lead form factor.
• Wide temperature capability with defined endurance: Rated from −55 °C to +105 °C with 2000 hours endurance at 105 °C for reliable performance in elevated-temperature applications.
• Clear ripple specifications: Both low-frequency (3.21 A at 120 Hz) and high-frequency (3.692 A at 10 kHz) ripple currents are provided to support design verification of AC stress handling.
• Measured loss characteristics: Dissipation factor (tan δ) specified at 0.88 (20 °C, 120 Hz), allowing engineers to account for loss in power and thermal calculations.
• Through-hole mounting ease: Radial-lead configuration with 10 mm lead spacing simplifies PCB placement and manual or wave-solder assembly processes.
• Regulatory compliance: RoHS compliance is documented for applications requiring restricted-substance conformity.
