UPJ2V3R3MPD

The UPJ2V3R3MPD is a radial-lead aluminum electrolytic capacitor from Nichicon, specified at 3.3 µF and 350 V. It is a low-impedance radial can designed for general-purpose use and is ideally suited for switching power supplies where stable filtering and ripple handling are required.

Compact mechanical dimensions (φ10 × 20L) and a broad operating temperature range make this part practical for power electronics designs that require predictable performance and long endurance under elevated temperature conditions.

Key Features

• Capacitance & Tolerance — 3.3 µF nominal capacitance with tolerance of -20% to 20% for predictable charge storage in power circuits.
• Rated Voltage — 350 V DC rating suitable for higher-voltage power rails and DC link filtering.
• Low Impedance Design — Series design targeted at low impedance; suitable for switching power supply applications that require tight filtering.
• Ripple Current Capability — Specified ripple handling of 54 mA at 120 Hz (low frequency) and 86.4 mA at 200 kHz (high frequency) for smoothing across a range of switching frequencies.
• Leakage Current — Leakage current specified at 146.2 µA for predictable quiescent behavior after voltage application.
• Endurance — Life rating of 5000 hours at 105 °C supporting extended operation in elevated-temperature environments.
• Temperature Range — Operates from -40 °C to 105 °C to cover typical industrial and power-electronics ambient conditions.
• Package & Mounting — Radial lead, can package with φ10 × 20L dimensions, 5 mm lead spacing (±0.5 mm); available in bulk or bag packing.
• Dielectric Loss (tan δ) — Specified tanδ of 0.2 (measured at 20 °C, 120 Hz), supporting assessment of ESR-related losses in design.
• Compliance — RoHS compliant for environmentally restricted designs.

Typical Applications

• Switching Power Supplies — Low-impedance design and series positioning make this capacitor suitable for output and bulk filtering in switching regulators.
• General-Purpose Power Filtering — 350 V rating and compact radial package allow use in a range of general-purpose AC/DC and DC power circuits.
• Ripple Smoothing in Power Modules — Defined low- and high-frequency ripple current specs help engineers size the part for smoothing at both line frequency and switching frequencies.

Unique Advantages

• Low-impedance construction: Designed for switching power supply environments to reduce voltage ripple and improve regulation stability.
• High-voltage capability: 350 V rating enables use on higher-voltage rails and DC link applications without up-rating components.
• Extended high-temperature endurance: 5000 hours at 105 °C provides predictable lifetime performance for demanding thermal environments.
• Compact radial can: φ10 × 20L package and 5 mm lead spacing support space-efficient board layouts and straightforward through-hole assembly.
• Quantified ripple and leakage specs: Published ripple current (54 mA @120 Hz, 86.4 mA @200 kHz) and leakage current (146.2 µA) enable accurate thermal and loss budgeting.
• RoHS compliance: Meets environmental restrictions for applied projects and procurement requirements.
