UVK2C331MHD

The UVK2C331MHD is a Nichicon UVK series aluminum electrolytic capacitor in a radial-lead can package. It delivers 330 µF capacitance at a 160 V rating with a compact φ18 × 35.5 mm case and is intended for general-purpose applications.

Designed for through-hole assemblies, the part combines a wide operating temperature range (−40 °C to 85 °C), defined endurance (2000 hours at 85 °C), and RoHS compliance for reliable performance in standard electronic designs.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 160 V rated voltage, providing substantial stored charge for higher-voltage general-purpose circuits.
• Radial Lead Package — Through-hole radial lead mounting in a φ18 × 35.5 mm can (lead spacing 7.5 mm) for easy PCB assembly and secure mechanical mounting.
• Temperature and Endurance — Operating temperature range −40 °C to 85 °C with endurance specified at 2000 hours at 85 °C, meeting defined life-cycle requirements for sustained use.
• Ripple Performance — Low-frequency ripple current of 800 mA (120 Hz) and high-frequency ripple current of 920 mA (10 kHz) to support AC ripple handling in circuits within these frequency bands.
• Leakage and Loss Angle — Specified leakage current of 2212 µA and tan δ (DF) of 0.2 measured at 20 °C, 120 Hz for predictable ESR-related behavior.
• Compact, Miniature Series Design — Part of the UVK miniature-sized series, noted for one-rank smaller case sizes versus UVR, enabling space-efficient layouts while maintaining standard electrolytic performance.
• Packaging & Compliance — Available in bulk (no terminal forming) or bag packing and compliant with RoHS requirements.

Typical Applications

• General-purpose electronics — Used where a 330 µF, 160 V polarized capacitor is required for energy storage or smoothing within general electronic assemblies.
• Through-hole assemblies — Radial lead format and can package suit PCB designs that rely on through-hole components for mechanical robustness and serviceability.
• Higher-voltage bulk capacitance — The 160 V rating with substantial capacitance supports designs needing bulk charge storage at elevated DC voltages within the specified temperature and endurance limits.

Unique Advantages

• High-voltage capability: 160 V rating allows integration into circuits operating at higher DC voltages without up-rating component count.
• Defined endurance specification: 2000 hours at 85 °C provides clear lifetime expectations for thermal and electrical stress planning.
• Measured ripple ratings: Specified ripple currents at both 120 Hz and 10 kHz give designers quantifiable limits for AC stress under low- and high-frequency conditions.
• Compact can size: φ18 × 35.5 mm case provides substantial capacitance in a space-efficient footprint, aligning with the UVK series’ miniature sizing approach.
• RoHS compliant: Meets RoHS directive requirements for use in lead-restricted end products.
• Simple procurement and handling: Bulk or bag packing options support flexible inventory and assembly workflows.
