UVP1H331MHD

The UVP1H331MHD is a bi-polarized aluminum electrolytic capacitor from Nichicon's UVP series, designed as a standard bi-polarized solution for entertainment electronics and general-purpose circuits. It delivers 330 µF capacitance at a 50 V rating in a radial-can package, offering defined ripple handling, wide operating temperature range, and RoHS compliance for consumer and commercial designs.

Key Features

• Electrical Performance: 330 µF nominal capacitance with ±20% tolerance and a 50 V rated voltage, suitable where bi-polarized capacitance is required.
• Ripple Current Capability: Rated ripple current of 650 mA at 120 Hz and 975 mA at 10 kHz, supporting varying-frequency ripple conditions within the specified limits.
• Temperature and Lifetime: Operates over –40 °C to +85 °C and is specified for 2000 hours at 85 °C with polarity inversion every 250 hours per the series endurance test.
• Leakage Current Spec: Series leakage current requirement: after 5 minutes’ application of rated voltage at 20 °C, leakage current is not more than 0.03 × C × V (µA), where C is capacitance and V is rated voltage.
• Package & Mounting: Radial lead (radial can) package with 7.5 mm lead spacing, leaded mounting for through-hole boards and prototyping.
• Dimensions: Compact footprint with length × diameter of approximately 2.5 × 1.6 cm and a seated height maximum of 2.5 cm, enabling placement in constrained assemblies.
• Regulatory Compliance: RoHS compliant according to the 2011/65/EU and (EU)2015/863 directives.

Typical Applications

• Entertainment Electronics — Part of Nichicon's standard bi-polarized UVP series targeted for entertainment electronics, making it suitable for consumer audio/video equipment designs that call for bi-polar capacitors.
• General-Purpose Consumer Electronics — Radial lead, bi-polarized construction and RoHS compliance suit a range of general-purpose applications in consumer and commercial products.
• Board-Level Replacement and Prototyping — Through-hole radial-lead format and standard lead spacing simplify use in repairs, prototypes, and legacy assemblies requiring a bi-polar electrolytic solution.

Unique Advantages

• Bi-polarized construction: Enables use where non-polar behavior is required, delivered in a standard UVP-series format designed for entertainment electronics.
• Defined ripple performance: Specified ripple current values at 120 Hz and 10 kHz provide clear design parameters for thermal and ripple budgeting in power-coupling applications.
• Wide operating temperature: Rated from –40 °C to +85 °C to accommodate common consumer and commercial environmental ranges.
• Endurance-verified: Designed to meet series endurance testing of 2000 hours at 85 °C with periodic polarity inversion, with capacitance and leakage retention criteria defined by the datasheet.
• RoHS compliance: Conforms to applicable RoHS directives, simplifying regulatory management for finished products.
• Practical radial-can form factor: Standard radial can and 7.5 mm lead spacing simplify integration into through-hole assemblies and replacement workflows.
