RNS1E150MDS1

The RNS1E150MDS1 from Nichicon is a conductive-polymer aluminum solid electrolytic capacitor in a radial-lead can designed for general-purpose electronic power applications. It delivers a compact 15 µF, 25 V polarized solution with low ESR and high ripple handling for decoupling and power-filtering tasks in board-level designs.

Built to the RNS series specifications, this part combines low loss (tanδ = 0.06 at 20°C/120 Hz), an extended operating range (−55°C to 105°C) and a 2000-hour endurance rating at 105°C for reliable operation in demanding thermal environments.

Key Features

• Conductive polymer aluminum construction — Solid electrolyte architecture for stable electrical performance and reduced equivalent series resistance compared to traditional electrolytics.
• Electrical ratings — 15 µF capacitance at a rated voltage of 25 V with capacitance tolerance of −20% to +20%.
• Low loss — tanδ = 0.06 measured at 20°C and 120 Hz, supporting efficient filtering and decoupling.
• Low ESR — 49 mΩ specified at 20°C/100 kHz, suitable for high-frequency decoupling and fast transient response.
• High ripple capability — Rated ripple currents of 220 mA at 120 Hz and 2.2 A at 300 kHz, enabling effective smoothing in both low- and high-frequency power paths.
• Leakage current — Specified leakage current of 75 µA after two minutes at rated voltage and 20°C, aiding predictable standby and bias behaviors.
• Temperature and endurance — Operating range −55°C to +105°C with endurance tested to 2000 hours at 105°C and rated voltage.
• Compact radial package — φ6.3 × 10 mm can with 2.5 mm lead spacing and radial lead mounting for through-hole PCB designs; available in bulk or bag packing.

Typical Applications

• DC-DC converter output filtering — Low ESR and high HF ripple current capability help smooth converter outputs and support transient loads.
• Power-supply decoupling — Compact 25 V, 15 µF value with low loss and low leakage for board-level decoupling near regulators and ICs.
• Consumer and industrial electronics — General-purpose energy storage and smoothing in control modules and compact power subsystems operating across −55°C to 105°C.

Unique Advantages

• Lower ESR at high frequency: 49 mΩ at 100 kHz provides improved efficiency for high-frequency decoupling compared with higher-ESR electrolytics.
• Wide operating temperature: −55°C to 105°C supports designs that must operate across broad environmental conditions.
• High-frequency ripple handling: 2.2 A ripple current at 300 kHz enables use in compact, high-switching-frequency power stages.
• Solid electrolyte reliability: Conductive polymer construction and 2000-hour endurance at 105°C deliver predictable long-term behavior in demanding thermal environments.
• Compact through-hole form factor: φ6.3 × 10 mm radial can with 2.5 mm lead spacing fits space-constrained PCB layouts while providing robust mechanical and electrical connections.
