UPJ0J272MHD

The UPJ0J272MHD is a Nichicon UPJ series miniature aluminum electrolytic capacitor designed for radial through-hole mounting. It delivers 2700 µF capacitance at a rated voltage of 6.3 V and is specified as a high-reliability, low-impedance device targeted at power conversion and general-purpose filtering.

Key value comes from its elevated temperature endurance and ripple capability: the part is specified for operation from −55°C to +105°C with a rated life of 5000 hours at 105°C, making it suitable for switching power supplies and other power-rail applications that require stable filtering and long-term reliability.

Key Features

• Capacitance & Voltage — 2700 µF (2.7 mF) nominal capacitance at a rated voltage of 6.3 V with a tolerance of −20% to +20%.
• Low loss (tan δ) — tanδ = 0.24 measured at 20°C, 120 Hz, 6.3 V, helping to minimize dissipation in filter and decoupling circuits.
• High ripple-current capability — Low-frequency ripple current 1.287 A (120 Hz) and high-frequency ripple current 1.43 A (200 kHz), supporting demanding ripple loads in switching supplies.
• High reliability / Endurance — Rated for 5000 hours at +105°C under load, providing extended life in high-temperature power environments.
• Radial through-hole package — Metal can, diameter φ12.5 × length 25 mm with 5 mm lead spacing (±0.5 mm), suited for PCB through-hole assemblies.
• Leakage current — Specified leakage current 510.3 µA, measurable after rated voltage application conditions.
• Regulatory — RoHS compliant for use in environmentally regulated designs.

Typical Applications

• Switching power supplies — Output filtering and bulk smoothing where low impedance and high ripple handling are required.
• General-purpose power filtering — Decoupling and bulk energy storage on power rails in consumer and industrial equipment.
• Through-hole DC‑DC converter modules — Radial-lead mounting for board-level power modules and assemblies.

Unique Advantages

• Sustained high-temperature performance: 5000-hour endurance at +105°C supports long operational life in thermally demanding assemblies.
• Strong ripple-handling capability: Rated ripple currents of 1.287 A (120 Hz) and 1.43 A (200 kHz) help maintain voltage stability under dynamic load.
• Compact radial footprint: φ12.5 × 25 mm can size with 5 mm lead spacing enables space-efficient through-hole designs.
• Low dissipation: tanδ = 0.24 at 20°C/120 Hz reduces internal heating and improves filtering efficiency.
• Regulatory readiness: RoHS compliance supports environmentally constrained product requirements.
