RNL1E561MDS4

The RNL1E561MDS4 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, designed for general-purpose power applications. It delivers 560 µF at a 25 V rating with a focus on low ESR, high ripple-current capability, and extended endurance for demanding board-level smoothing and decoupling tasks.

Key Features

• Core Technology Conductive polymer aluminum solid electrolyte for stable electrical characteristics and reliable performance.
• Capacitance & Voltage 560 µF nominal capacitance with ±20% tolerance at 120 Hz, rated for 25 V operation.
• Low ESR & Frequency Performance ESR of 10 mΩ measured at 20°C/100 kHz and tanδ of 0.12 (20°C, 120 Hz) for reduced losses and improved high-frequency behavior.
• High Ripple-Current Capability Rated ripple current of 580 mA at 120 Hz (low frequency) and 5.8 A at 300 kHz (high frequency) to support switching power stages and high-frequency converters.
• Temperature & Endurance Wide operating range from –55°C to +105°C with rated load life of 2000 hours at 105°C.
• Package & Mounting Radial lead can with φ10 mm body diameter and 5 mm lead spacing; available in bulk or bag packing for manual or automated through-hole assembly.
• Environmental Compliance RoHS compliant and in mass production for supply stability.

Typical Applications

• Power supply smoothing — Bulk smoothing and output filtering on 25 V rails where low ESR and high ripple capability reduce voltage ripple and heat dissipation.
• High-frequency converters — Output decoupling in switching regulators and DC‑DC converters that operate at 100 kHz–300 kHz, leveraging the low ESR at 100 kHz and elevated ripple current rating.
• Embedded and industrial electronics — General-purpose board-level energy storage and decoupling across a wide temperature range (–55°C to +105°C) and long endurance requirements.

Unique Advantages

• Reduced power loss: 10 mΩ ESR at 100 kHz minimizes I²R losses in high-current paths.
• Handles high-frequency stress: 5.8 A ripple capability at 300 kHz supports aggressive switching topologies and reduces the need for parallel capacitors.
• Wide thermal tolerance: –55°C to +105°C operation enables use across industrial and temperature-variable environments.
• Measured stability: tanδ of 0.12 (20°C, 120 Hz) and specified leakage current (1,400 µA) provide predictable behavior for design margining.
• Through-hole convenience: Radial lead form factor with 5 mm lead spacing simplifies replacement and prototyping workflows.
• Production-ready: RoHS compliance and mass production status support volume deployment and procurement planning.
