RNS1E100MDS1

The RNS1E100MDS1 from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a compact radial can package. It delivers 10 µF capacitance at a 25 V rating with a low ESR and high ripple current capability for demanding general-purpose electronic designs.

Designed for applications that require compact size and reliable performance across a wide temperature range, this radial-lead capacitor combines low leakage and a 2000-hour endurance at 105 °C to support long-term operation in small form-factor circuits.

Key Features

• Capacitance & Tolerance — 10 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20 °C), providing predictable charge storage for circuit design.
• Rated Voltage — 25 V rated voltage suitable for many intermediate-voltage rail applications.
• Low ESR — 63 mΩ equivalent series resistance measured at 20 °C/100 kHz, enabling improved high-frequency performance and reduced loss.
• High Ripple Current Capacity — 170 mA at 120 Hz (low frequency) and 1.7 A at 300 kHz (high frequency), supporting both low- and high-frequency ripple conditions.
• Leakage Current — Low leakage current of 50 µA after 2 minutes at rated voltage and 25 °C, aiding in low-standby-power designs.
• Temperature & Endurance — Rated for operation from −55 °C to 105 °C with a 2000-hour endurance at 105 °C under rated voltage.
• Compact Radial Package — Size φ6.3 × 7 mm with 2.5 mm lead spacing (±0.5 mm), ideal for space-constrained board layouts and through-hole assembly.

Typical Applications

• General Purpose Electronics — Use where compact energy storage and stable capacitance are required across a broad temperature range.
• Power Supply Filtering — Low ESR and high ripple current ratings support smoothing and decoupling of intermediate power rails in small power modules.
• High-Frequency Circuits — 63 mΩ ESR at 100 kHz and a 1.7 A rating at 300 kHz make this capacitor suitable for high-frequency ripple handling and noise attenuation.

Unique Advantages

• Balanced Low ESR and Ripple Capability: 63 mΩ ESR (20 °C/100 kHz) combined with 1.7 A high-frequency ripple rating enables efficient performance in demanding ripple environments.
• Wide Temperature Range: Operation from −55 °C to 105 °C ensures functionality across industrial temperature conditions.
• Long Endurance at Elevated Temperature: 2000 hours at 105 °C under rated voltage provides a measurable life specification for design reliability planning.
• Compact Through-Hole Form Factor: φ6.3 × 7 mm radial can with 2.5 mm lead spacing offers a small footprint for densely populated PCBs while maintaining through-hole robustness.
• Low Standby Leakage: 50 µA leakage current supports low-power and standby-sensitive applications.
