RNS1E220MDN1

The RNS1E220MDN1 from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in the RNS series, offered as a radial-lead, polarized can. It provides 22 µF capacitance at a 25 V rating and is intended for general-purpose board-level power and signal applications.

Key value comes from a compact φ8×11.5 mm can with low ESR and high ripple-current capability, combined with a wide operating temperature range and a 2000-hour endurance at 105°C for reliable performance in demanding environments.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance at a 25 V rated voltage with a capacitance tolerance of -20%~20%.
• Conductive Polymer Electrolyte — Solid conductive polymer construction for stable electrical characteristics across temperature and frequency.
• Low ESR — ESR of 28 mΩ measured at 20°C/100 kHz, supporting efficient power delivery and low loss at high frequencies.
• High Ripple Current — Rated ripple current of 340 mA at 120 Hz (low frequency) and 3.4 A at 300 kHz (high frequency), enabling handling of both low- and high-frequency ripple loads.
• Loss Angle — tanδ = 0.06 specified at 20°C, 120 Hz for predictable dissipation characteristics.
• Reliability and Endurance — 2000 hours endurance at 105°C under rated voltage; leakage current specified at 110 µA.
• Compact Radial Package — φ8 × 11.5 mm can with 3.5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for volume assembly.
• Operating Range — Rated to operate from -55°C to 105°C for broad environmental compatibility.
• Production Status — Mass production availability from Nichicon's RNS series.

Typical Applications

• General-purpose board-level power — Where a 22 µF, 25 V capacitor with low ESR and high ripple handling is required for power conditioning and stability.
• High-frequency power circuits — Suited to designs that demand low ESR at 100 kHz and high ripple-current capability up to 3.4 A at 300 kHz.
• Temperature-demanding environments — Applications requiring operation across -55°C to 105°C and verified endurance at 105°C for up to 2000 hours.

Unique Advantages

• Low-loss performance: 28 mΩ ESR at 100 kHz and tanδ 0.06 at 120 Hz minimize power dissipation in high-frequency circuits.
• High ripple tolerance: Rated ripple current up to 3.4 A at 300 kHz supports demanding AC and switching conditions on power rails.
• Thermal endurance: 2000-hour life at 105°C provides predictable long-term stability under elevated-temperature operation.
• Compact radial form factor: φ8×11.5 mm can with 3.5 mm lead spacing provides a space-efficient, through-hole option for assembly and prototyping.
• Conductive polymer benefits: Solid electrolyte chemistry delivers stable electrical characteristics and leakage behavior (110 µA) after standard conditioning.
• Production-ready packaging: Available in bulk or bag packing and currently in mass production for volume deployment.
