UPJ2F330MHD

The UPJ2F330MHD is a Nichicon UPJ-series aluminum electrolytic capacitor in a radial-lead can designed for general-purpose power applications, with features aimed at switching power supply use. It pairs a 33 µF capacitance with a 315 V rating and a compact φ16 × 30.5 mm package for through-hole implementations.

Key design attributes include low impedance characteristics from the UPJ series, rated endurance under elevated temperature, and measurable ripple and leakage performance—making it suitable where reliable bulk or decoupling capacitance is required in power-electronics designs.

Key Features

• Electrical Ratings — 33 µF nominal capacitance with a capacitance tolerance of ±20% and a rated voltage of 315 V.
• Low-loss Performance — tanδ of 0.2 measured at 20°C, 120 Hz to characterize dissipation for power and filter applications.
• Ripple Current Capability — Low-frequency ripple current: 185 mA at 120 Hz; High-frequency ripple current: 296 mA at 200 kHz, enabling effective smoothing across common switching and mains frequencies.
• Leakage Current — Specified leakage current of 515.8 µA for predictable standby and no-load behavior.
• Thermal and Endurance — Rated operating temperature range −40°C to +105°C with a load life (endurance) of 5000 hours at 105°C.
• Package and Mounting — Radial lead (through-hole) can, size φ16 × 30.5 mm, lead spacing 7.5 mm with ±0.5 mm tolerance; available in bulk (no terminal forming) or bag packing.
• Compliance — RoHS compliant per provided product data.

Typical Applications

• Switching power supplies — Bulk or rail decoupling where low impedance and endurance at elevated temperature are required.
• Power filtering — AC/DC and DC/DC converters that need ripple attenuation at both low (120 Hz) and high (200 kHz) frequencies.
• General-purpose power electronics — Through-hole designs requiring a compact, polarized capacitor with a 315 V rating for board-level energy storage and smoothing.

Unique Advantages

• High-voltage capability: 315 V rating supports designs with elevated DC link or high-voltage rails.
• Long-term thermal endurance: 5000 hours at 105°C delivers predictable aging behavior for designs exposed to sustained heat.
• Broad ripple performance: Specified ripple current values at 120 Hz and 200 kHz make the part usable across switching and line-frequency conditions.
• Compact radial can: φ16 × 30.5 mm size and 7.5 mm lead spacing fit common through-hole layouts while providing measurable capacitance and voltage headroom.
• Measured loss and leakage figures: Specified tanδ and leakage current allow engineers to budget dissipation and standby currents accurately.
• RoHS compliant: Meets environmental compliance requirements listed in the product data.
