RNE1E561MDNASQ

The RNE1E561MDNASQ is a conductive polymer aluminum solid electrolytic capacitor from Nichicon’s RNE series. It delivers high capacitance in a compact radial can package and is designed for general-purpose power applications.

Key value propositions include low ESR, high ripple-current capability, a 5000-hour load life at 105°C, and compatibility with lead-free flow soldering processes. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — Rated at 560 µF and 25 V, providing substantial bulk capacitance for power smoothing and energy storage in compact assemblies.
• Low ESR — ESR specified at 20 mΩ (measured at 100 kHz, 20°C), enabling improved high-frequency performance and reduced loss under ripple stress.
• High Ripple Current — Rated ripple-current capability of 3.1 A at 300 kHz and 310 mA at 120 Hz, supporting demanding AC ripple and switching converter environments.
• Thermal & Lifetime Performance — Operating temperature range −55°C to +105°C with a rated load life of 5000 hours at 105°C for extended reliability under elevated temperature.
• Package & Mounting — Radial lead (radial, can) package with 5 mm lead spacing and compact dimensions (L: 1.25 × D: 1.00 cm), suitable for through-hole assemblies and PCB-mounted power rails.
• Polarity & Tolerance — Polarized capacitor with capacitance tolerance of −20% to +20% (±20%).
• RoHS & Soldering — RoHS compliant and compatible with lead-free flow soldering conditions.

Typical Applications

• Power-supply smoothing — Bulk decoupling and smoothing on linear and switching power supplies where high capacitance and low ESR reduce output ripple.
• DC‑DC converters — Input/output filtering and energy buffering in point-of-load converters that require high ripple-current handling at switching frequencies.
• General-purpose electronics — Board-level energy storage and transient suppression in consumer and industrial electronic assemblies operating within −55°C to +105°C.

Unique Advantages

• High capacitance in a compact radial can — 560 µF in a small footprint supports space-constrained designs without sacrificing energy storage.
• Low loss under AC stress — 20 mΩ ESR at 100 kHz helps minimize heating and improves efficiency in high-frequency circuits.
• High ripple tolerance — 3.1 A at 300 kHz and 310 mA at 120 Hz enable reliable operation in switching environments and high-frequency filtering.
• Robust thermal endurance — 5000 hours at 105°C provides a long operational life for applications exposed to sustained elevated temperatures.
• Manufacturing-friendly — Radial lead package with lead-free flow soldering correspondence eases through-hole assembly and complies with RoHS requirements.
