UPJ1J330MED

The UPJ1J330MED is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPJ series, designed for low-impedance power applications. With a 33 µF capacitance at 63 V and a compact φ6.3 × 15 mm can, it addresses general-purpose power filtering and decoupling needs where through-hole mounting is required.

Engineered for switching power supplies and similar circuits, this part combines low loss (tan δ) and controlled leakage with rated ripple current performance and a -55 °C to +105 °C operating range for reliable operation across typical electronic equipment environments.

Key Features

• Capacitance & Voltage — 33 µF capacitance rated at 63 V with ±20% tolerance, providing bulk decoupling and energy storage for mid-voltage rails.
• Low Loss / Low Impedance — Tangent of loss angle (tan δ) of 0.08 (max) in the 63 V rating group, supporting improved AC performance in power circuits.
• Controlled Leakage — Specified leakage current approximately 62.37 µA (0.03 · C · V), measured after 1 minute at 20 °C, for predictable bias behavior.
• Ripple Current Capability — Rated ripple performance of 85 mA at 120 Hz and 170 mA at 200 kHz to handle AC stress in switching supply outputs and filters.
• Operating Temperature & Lifetime — Rated for -55 °C to +105 °C operation with a specified life of 2000 hours at 105 °C for lifecycle planning.
• Through‑Hole Radial Package — φ6.3 × 15 mm can with 2.5 mm lead spacing and radial leads for easy insertion into prototype and legacy through‑hole PCBs.
• RoHS Compliant — Meets RoHS environmental requirements.
• Product Status — End Of Life; check availability and lead times when planning procurement.

Typical Applications

• Switching Power Supplies — Low-impedance performance and rated ripple current make this capacitor suitable for output smoothing and decoupling in switching regulators.
• General-Purpose Power Filtering — Bulk decoupling on mid-voltage rails and power distribution lines in electronic assemblies.
• Through‑Hole/Repair Boards — Radial-lead format fits through-hole PCBs and is convenient for prototyping, repair, and legacy designs.

Unique Advantages

• Measurable leakage behavior — Specified leakage current allows designers to predict bias drain and select appropriate bleeder or balancing networks.
• Low loss under DC bias — 0.08 tan δ at the 63 V rating supports lower dissipation and improved AC performance in power circuits.
• Compact through‑hole footprint — φ6.3 × 15 mm can and 2.5 mm lead spacing save board area while retaining through‑hole robustness.
• Broad temperature range — -55 °C to +105 °C rating enables use across a wide variety of equipment operating conditions.
• Clear lifecycle status — End Of Life designation provides a known procurement constraint for production planning and lifecycle management.
• RoHS compliance — Aligns with environmental requirements for product assemblies.
