UPJ1E271MPD

The UPJ1E271MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series, specified at 270 µF and 25 V. It delivers low impedance and stable performance across a wide temperature range for general-purpose power filtering and energy storage in board-level power designs.

Engineered for switching power supplies and general-purpose power applications, this φ8 × 20 mm radial can provides measurable ripple-handling, controlled loss tangent, and a specified endurance at elevated temperature for reliable operation in demanding environments.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance at a rated voltage of 25 V with tolerance ±20%.
• Low loss (tan δ) — Loss tangent (tanδ) specified at 0.14 measured at 20°C, 120 Hz, 25 V for predictable dissipation in AC and ripple environments.
• Ripple current capability — Low-frequency ripple current 319.2 mA (120 Hz) and high-frequency ripple current 560 mA (200 kHz) to support smoothing and decoupling in switching supplies.
• Leakage current — Specified leakage current of 202.5 µA for controlled standby and bias leakage behavior.
• Thermal and endurance rating — Operating temperature range −55°C to +105°C with a rated load life of 3000 hours at 105°C for this case size.
• Radial can package — φ8 × 20 mm can with 3.5 mm lead spacing (±0.5 mm) and radial leads for through-hole mounting and prototyping ease.
• RoHS compliant — Meets RoHS directive requirements for reduced hazardous substances.

Typical Applications

• Switching power supplies — Bulk smoothing and output filtering where low impedance and reliable ripple handling are required.
• DC‑DC converters — Energy storage and decoupling on intermediate and output rails to stabilize voltage under dynamic load conditions.
• Embedded and industrial power rails — General-purpose decoupling and hold-up capacitance in consumer and industrial electronics operating across −55°C to +105°C.

Unique Advantages

• Low-impedance design — Optimized for reduced impedance and predictable performance in switching environments, improving ripple attenuation.
• Measured ripple specifications — Separate low- and high-frequency ripple current ratings (319.2 mA at 120 Hz; 560 mA at 200 kHz) to help designers size components for actual operating spectra.
• Temperature and endurance specification — Rated for −55°C to +105°C with a 3000 hour load life at 105°C for the φ8 case, supporting longer-term reliability under elevated temperature stress.
• Compact radial package — φ8 × 20 mm can with 3.5 mm lead spacing offers a compact, easy-to-mount solution for through-hole assemblies and prototyping.
• Predictable leakage and loss — Specified leakage current and tanδ enable accurate power-loss budgeting and thermal planning in design validation.
• RoHS compliance — Conforms to RoHS requirements for use in regulated product lines.
