RE50E561MDN1

The RE50E561MDN1 is a conductive polymer aluminum solid electrolytic capacitor from Nichicon's RE5 series. It delivers a 560 µF capacitance at a 2.5 V rating in a compact, low-profile φ8×8 mm radial-can package with 3.5 mm lead spacing.

Designed for general-purpose electronic designs, this capacitor combines ultra-low ESR, high ripple-current capability, and a long 2,000-hour life at 105 °C to support power stages and high-frequency circuits that demand stable decoupling and energy storage in a small footprint.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance at a rated voltage of 2.5 V with ±20% tolerance (120 Hz, 20 °C).
• Conductive Polymer Dielectric — Solid polymer construction provides low-loss characteristics demonstrated by a tan δ of 0.10 at 120 Hz, 20 °C.
• Ultra-low ESR — ESR of 5 mΩ measured at 100 kHz, 20 °C for improved transient response and reduced dissipation in high-current paths.
• High Ripple Current Capability — Rated ripple current up to 6.3 A at 300 kHz (frequency coefficient 1.00) and 6,300 mArms at 105 °C/100 kHz, enabling use in high-frequency power circuits.
• Robust Thermal Performance — Operating temperature range from −55 °C to +105 °C with a rated endurance of 2,000 hours at 105 °C under rated voltage.
• Low Leakage — Leakage current specified at 500 µA after 2 minutes at 25 °C under rated voltage, supporting designs where standby and bias currents matter.
• Compact Radial Package — φ8×8 mm can with 3.5 mm lead spacing and radial leads for through-hole mounting and straightforward board assembly.

Typical Applications

• Power Supply Decoupling — Low ESR and high ripple-current rating make this capacitor suitable for decoupling on regulator outputs and switching supply stages.
• High-Frequency Power Circuits — Performance at 100 kHz–300 kHz frequencies supports use in converters and point-of-load filtering where fast transient handling is required.
• General-Purpose Electronic Designs — Compact, radial-can form factor and wide operating temperature range suit a broad set of general-purpose applications requiring reliable bulk capacitance.

Unique Advantages

• Low-loss polymer construction: Provides a tan δ of 0.10 for reduced dielectric losses and improved efficiency in AC and switching environments.
• Superior transient handling: 5 mΩ ESR and high rated ripple current enable tighter voltage regulation and lower thermal stress in power subsystems.
• Long-term reliability: 2,000-hour endurance at 105 °C under rated voltage supports stable capacitance and ESR over extended thermal loading.
• Compact board footprint: φ8×8 mm package with 3.5 mm lead spacing delivers significant capacitance density for space-constrained through-hole designs.
• Predictable leakage: Specified 500 µA leakage current after two minutes at 25 °C aids in power-budget planning and bias stability.

Why Choose RE50E561MDN1?

The RE50E561MDN1 balances compact size with performance attributes that matter in power-sensitive designs: conductive polymer construction for low loss, an ultra-low ESR of 5 mΩ for fast transient response, and high ripple-current capability up to 6.3 A at high frequency. Its 2,000-hour life at 105 °C and −55 °C to +105 °C operating range provide a predictable durability profile for demanding thermal environments.

This capacitor is well suited to engineers and procurement teams specifying general-purpose, through-hole bulk capacitance for power decoupling, filtering, and energy storage where low ESR, high ripple handling, and a small radial-can footprint are required.
