UVZ1A331MED

The UVZ1A331MED is a Nichicon UVZ series aluminum electrolytic capacitor in a radial-lead can intended for general-purpose electronic applications. It delivers 330 µF of capacitance at a 10 V rating in a compact φ6.3 × 11 mm package with 2.5 mm lead spacing.

Key electrical characteristics include a rated operating temperature range of −55°C to 105°C, measured tanδ of 0.24 (20°C, 120 Hz), specified ripple current values, and a rated endurance of 1000 hours at 105°C. Status: End Of Life.

Key Features

• Electrical Performance 330 µF capacitance at 10 V with a tolerance of −20% to +20% and measured tanδ = 0.24 (20°C, 120 Hz).
• Ripple Current Handling Low-frequency ripple current 210 mA (120 Hz) and high-frequency ripple current 315 mA (10 kHz).
• Leakage Current Specified leakage current: 99 µA.
• Reliability & Endurance Rated life: 1000 hours at 105°C, providing defined performance over time under rated conditions.
• Wide Temperature Range Operates from −55°C to 105°C to support designs exposed to broad ambient conditions.
• Mechanical & Mounting Radial lead can package, dimensions φ6.3 × 11 mm, lead spacing 2.5 mm (tolerance ±0.5 mm), suitable for through-hole assemblies.
• Packaging Options Available in Bulk (no terminal forming) or Bag packing.
• Environmental RoHS compliant.

Typical Applications

• General Purpose Electronics — Suited for circuit designs that require a polarized aluminum electrolytic capacitor with 330 µF at 10 V.
• Through-Hole Assemblies — Radial lead format and 2.5 mm lead spacing for board-level through-hole mounting and manual or wave-solder assembly.
• Temperature-Variable Environments — Designed for use across −55°C to 105°C where defined electrical behavior over wide temperature is required.
• Production and Prototyping — Bulk and bag packing options support both prototype runs and volume placement.

Unique Advantages

• Defined High-Temperature Endurance: 1000 hours at 105°C gives predictable lifetime behavior for thermal-stressed designs.
• Measured Dielectric Loss (tanδ): tanδ = 0.24 (20°C, 120 Hz) at the 10 V rating supports designers needing explicit loss characteristics for AC and ripple calculations.
• Dual-Frequency Ripple Ratings: Separate low-frequency (210 mA at 120 Hz) and high-frequency (315 mA at 10 kHz) ripple current specifications help size the capacitor for expected ripple spectra.
• Compact Radial Can: φ6.3 × 11 mm package provides a small footprint for through-hole designs where board space is limited.
• RoHS Compliance: Meets RoHS directive requirements for lead-free assembly environments.
• Flexible Packaging: Bulk or bag options simplify procurement for prototypes or production runs.
