UPJ2A561MHD

The UPJ2A561MHD is a Nichicon UPJ series aluminum electrolytic capacitor in a radial-can package designed for power applications. It offers 560 µF capacitance at a 100 V rating and is optimized for switching power supplies and general-purpose power filtering where low impedance and long life are required.

Key value comes from a compact φ18 × 35.5 mm can, radial lead terminations with 7.5 mm lead spacing, and a guaranteed endurance of 5000 hours at +105°C, making it suitable for applications that demand stable performance under sustained thermal stress.

Key Features

• Capacitance & Voltage: 560 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C), providing energy storage and smoothing for medium-voltage power rails.
• Low Impedance, Power-Focused Design: Part of the UPJ series characterized for low impedance performance suitable for switching power supplies, enabling efficient ripple filtering and stable DC output.
• High Endurance: Rated for 5000 hours at +105°C under load, supporting long-term reliability in thermally demanding environments.
• Ripple Current Capability: Low-frequency ripple current of 1.092 A (120 Hz) and high-frequency ripple current of 1.68 A (200 kHz), supporting both mains-frequency and high-frequency switching applications.
• Construction & Mounting: Radial lead, polarized aluminum can (φ18 × 35.5 mm) with 7.5 mm lead spacing (±0.5 mm) and lead diameter 0.8 mm, for through-hole PCB assembly and secure mechanical retention.
• Operating Range & Compliance: Wide operating temperature range from −55°C to +105°C and RoHS compliance for environmental requirements.
• Packaging & Availability: Available in bulk (no terminal forming) or bag packing and currently in mass production for production-level procurement.

Typical Applications

• Switching Power Supplies: Low impedance and specified high-frequency ripple current make this capacitor suitable for output smoothing and decoupling in SMPS designs.
• Power Filtering and Smoothing: 560 µF at 100 V provides bulk energy storage and ripple reduction on DC rails in industrial and commercial power systems.
• General-Purpose Power Electronics: Radial-lead mounting and robust temperature/endurance specifications support use in general-purpose power modules, controllers, and assemblies.

Unique Advantages

• Designed for Switching Environments: Series-level low-impedance design targets switching power supply performance, translating to improved ripple suppression where it matters.
• Long-Life Reliability: 5000 hours at +105°C endurance rating gives predictable lifetime performance for sustained high-temperature operation.
• High Voltage Handling: 100 V rating enables use on higher-voltage rails without multiple-component topologies, simplifying designs.
• Clear Mechanical Specification: φ18 × 35.5 mm can with 7.5 mm lead spacing (±0.5 mm) and 0.8 mm lead diameter supports straightforward through-hole assembly and mechanical stability.
• Production-Ready Supply: Mass-production status and standard bulk/bag packaging options ease procurement and PCB assembly planning.
