UPJ1E561MPD

The UPJ1E561MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPJ series. It is a radial-lead, polarized capacitor providing 560 µF at a rated voltage of 25 V, optimized for power filtering and energy storage in compact designs.

Designed for applications such as switching power supplies, the UPJ1E561MPD combines low impedance characteristics with extended load-life performance, making it suitable for systems that require stable capacitance, ripple handling, and operation across a wide temperature range.

Key Features

• Capacitance and Voltage — 560 µF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of −20% to +20%.
• Low Dissipation Factor — tanδ (DF) = 0.14 measured at 20°C, 120 Hz, indicating low loss for efficient power filtering.
• High Ripple Current Capability — Low-frequency ripple current 643.5 mA (120 Hz) and high-frequency ripple current 990 mA (200 kHz) to support converter and regulator applications.
• Leakage Current — Leakage current specified at 420 µA for stable long-term operation after application of rated voltage.
• Extended Load Life — Rated for 5000 hours at 105°C, providing endurance for high-temperature operating environments.
• Wide Temperature Range — Operational from −55°C to +105°C to cover demanding environmental conditions.
• Compact Radial Package — Can size φ10 × 25 mm length with 5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assemblies.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible procurement and handling.
• RoHS Compliant — Conforms to RoHS environmental requirements.

Typical Applications

• Switching Power Supplies — Bulk and smoothing capacitance for input/output stages, leveraging low impedance and high ripple capability.
• DC–DC Converters — Energy storage and ripple suppression in compact regulator modules where high-frequency ripple handling is required.
• Industrial Power Electronics — Filtering and decoupling in industrial control systems that operate across wide temperature ranges.
• Telecommunications and Networking — Power conditioning and hold-up capacitance in network equipment and telecom power rails.

Unique Advantages

• Robust high-temperature endurance: 5000 hours at 105°C supports long-term reliability in elevated ambient conditions.
• Strong ripple handling across frequencies: Specified ripple currents of 643.5 mA (120 Hz) and 990 mA (200 kHz) enable effective filtering for both low- and high-frequency noise.
• Low dissipation for efficient operation: tanδ of 0.14 at 20°C, 120 Hz contributes to reduced heat generation and stable performance.
• Compact, board-friendly form factor: φ10 × 25 mm radial can with 5 mm lead spacing simplifies placement in space-constrained through-hole designs.
• Clear procurement options: Available in bulk or bag packing for production and prototyping workflows.
• Regulatory compliance: RoHS status ensures conformity with environmental requirements.
