UPJ1E271MPD6

The UPJ1E271MPD6 is a radial lead aluminum electrolytic capacitor with 270 µF capacitance and a 25 V rating, designed as part of Nichicon's UPJ series for low-impedance applications such as switching power supplies. It provides a compact φ10 × 16 mm can and polarized radial-lead construction for through-hole mounting and general-purpose power smoothing.

Key value propositions include low impedance behavior for power supply use, extended endurance under load (5,000 hours at 105°C for the applicable case size), and RoHS compliance for regulated designs.

Key Features

• Capacitance and Rating — 270 µF nominal capacitance with a tolerance of −20% to +20% and a rated voltage of 25 V.
• Low Impedance UPJ Series — Part of the UPJ line characterized as "Low Impedance, For Switching Power Supplies," providing improved ripple handling in power circuits.
• Endurance — Rated for 5000 hours of load life at +105°C (per series specifications), supporting long-term operation under elevated temperature and ripple stress.
• Ripple Performance — Specified low-frequency ripple current of 299.3 mA at 120 Hz and high-frequency ripple current of 525 mA at 200 kHz to address both bulk and high-frequency ripple components.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.14 measured at 20°C, 120 Hz for the 25 V rating, enabling predictable dissipation behavior in designs.
• Leakage Current — Specified leakage current of 202.5 µA, useful for budgeting standby current in power designs.
• Operating Temperature Range — −55°C to +105°C, accommodating a wide range of environmental conditions.
• Mechanical Package — Radial, can-type package with dimensions φ10 × 16 mm, lead spacing 5.0 mm (±0.5 mm), and bulk/bag packing options (no terminal forming).
• Environmental Compliance — RoHS compliant as specified in the product data.

Typical Applications

• Switching Power Supplies — Low impedance characteristics and rated ripple currents make this capacitor well suited for smoothing and energy storage in switch-mode power supplies.
• General-Purpose Power Filtering — Use in through-hole designs requiring 270 µF at 25 V for bulk filtering and stabilization of DC rails.
• Electronics Requiring Extended Endurance — Applications that operate at elevated temperatures and require long load life (specified 5000 h at 105°C) will benefit from the UPJ1E271MPD6’s endurance rating.
