UPJ1E561MHD6

The UPJ1E561MHD6 is a radial-lead aluminum electrolytic capacitor in the Nichicon UPJ series, optimized for low impedance and reliable performance in power applications. With a rated capacitance of 560 µF at 25 V and a compact can size (φ12.5×15L), it is intended for general-purpose use including switching power supplies and power-rail smoothing.

Key value comes from a combination of low loss (tanδ 0.14 at 20°C, 120 Hz), solid ripple handling (559 mA at 120 Hz and 860 mA at 200 kHz), and a long rated load life of 5000 hours at 105°C—delivering stable capacitance and controlled leakage over extended operation.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance at a rated voltage of 25 V and tolerance ±20% (120 Hz, 20°C).
• Low Impedance Design — Series design emphasis on low impedance for improved performance in switching power supplies and DC‑DC converters.
• High Endurance — Rated for 5000 hours at 105°C under load, maintaining capacitance within ±20% and leakage within specified limits.
• Ripple Current Capability — Low-frequency ripple 559 mA (120 Hz) and high-frequency ripple 860 mA (200 kHz) for effective smoothing of supply rails.
• Loss Characteristics — Tangent of loss angle (tanδ) specified at 0.14 for 25 V units (20°C, 120 Hz), aiding predictable AC performance.
• Leakage Current — Specified leakage current of 420 µA after 1 minute at rated voltage and 20°C for this part.
• Package & Mounting — Radial-lead can (φ12.5 mm diameter × 15 mm length) with 5.0 mm lead spacing and 0.5 mm spacing tolerance; bulk/bag packing available.
• Wide Temperature Range — Operates from −55°C to +105°C to support varied environmental conditions.
• RoHS Compliant — Meets RoHS directive requirements as noted for the UPJ series.

Typical Applications

• Switching Power Supplies — Low-impedance construction and robust ripple handling make it suitable for input/output smoothing in switching regulators.
• Power-Rail Smoothing — Provides bulk capacitance and transient buffering on DC power rails in general-purpose electronic equipment.
• DC-DC Converters — Useful for energy storage and filtering where compact, radial electrolytics are required.
• Embedded and Industrial Electronics — Long endurance at 105°C supports sustained operation in industrial-grade power subsystems.

Unique Advantages

• Long Load-Life Endurance: 5000 hours at 105°C ensures stable capacitance and controlled leakage over extended duty cycles.
• High Ripple Capacity: Combined low- and high-frequency ripple ratings (559 mA @120 Hz, 860 mA @200 kHz) support a range of power-conversion frequencies.
• Compact Radial Can: φ12.5×15L packaging with 5 mm lead spacing provides a small footprint for board-level power filtering.
• Predictable AC Loss: Specified tanδ of 0.14 at 25 V gives predictable dissipation characteristics for thermal and stability planning.
• Wide Operating Temperature: −55°C to +105°C rating supports designs exposed to varied thermal environments.
• Regulatory Compliance: RoHS compliance reduces material-restriction risk for global products.
