UPJ1K330MPD

The UPJ1K330MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPJ series designed for low-impedance, general-purpose power applications. It provides 33 µF capacitance at a rated voltage of 80 V in a compact φ8 × 11.5 mm can with 3.5 mm lead spacing.

Engineered for power filtering in switching power supplies and other DC power stages, this polarized capacitor combines a wide operating temperature range (−55 °C to +105 °C) with a rated endurance of 3000 hours at 105 °C.

Key Features

• Capacitance & Voltage: 33 µF nominal capacitance with a rated voltage of 80 V and capacitance tolerance of −20% to +20%.
• Low Impedance Design: Part of Nichicon’s UPJ series specified for low impedance, suitable for switching power supply filtering and decoupling.
• Thermal Endurance: Rated for operation from −55 °C to +105 °C with a 3000-hour life rating at 105 °C for the φ8 case size.
• Ripple Current Handling: Low-frequency ripple current 66 mA at 120 Hz and high-frequency ripple current 132 mA at 200 kHz for power-stage ripple management.
• Leakage & Dissipation Factor: Leakage current 79.2 µA (measured condition consistent with 0.03CV) and tanδ 0.08 at 20 °C, 120 Hz, 80 V indicating controlled losses.
• Package & Mounting: Radial lead, through-hole can (φ8 × 11.5 mm), lead spacing 3.5 mm (±0.5 mm), available in bulk or bag packing.
• RoHS Compliant: Conforms to RoHS requirements as specified in the product documentation.

Typical Applications

• Switching Power Supplies: Low-impedance filtering and energy storage in SMPS outputs and intermediate rails.
• General Power Filtering: Bulk and decoupling capacitor for DC power rails in electronic systems requiring an 80 V rated capacitor.
• Through-Hole PCB Designs & Prototyping: Radial-lead form factor and bulk/bag packaging make it suitable for prototyping, repairs, and through-hole production boards.

Unique Advantages

• Compact high-voltage filtering: 33 µF at 80 V in a φ8 × 11.5 mm can provides space-efficient bulk capacitance for higher-voltage rails.
• Temperature and life specification: Rated to −55 °C to +105 °C with 3000 hours endurance at 105 °C for reliable operation under sustained elevated temperature.
• Measurable ripple capability: Defined ripple current values at 120 Hz and 200 kHz help engineers size the capacitor for both low- and high-frequency ripple conditions.
• Controlled leakage and loss: Leakage current of 79.2 µA and tanδ of 0.08 (20 °C, 120 Hz, 80 V) support predictable performance in power circuits.
• Through-hole convenience: Radial-lead packaging with 3.5 mm lead spacing simplifies hand assembly, wave/flow solder compatibility for through-hole processes, and board repair.
• Regulatory compliance: RoHS compliant for use in designs that require restricted-substance conformance.
