RS61C101MDS1

The RS61C101MDS1 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, part of Nichicon’s RS6 series. It provides 100 µF capacitance at a 16 V rating in a miniature φ6.3 × 6 mm package designed for general-purpose power decoupling and energy-storage duties.

Engineered for low ESR and high ripple handling, this component delivers 24 mΩ ESR (20°C/100 kHz), high-frequency ripple tolerance up to 2.49 A (300 kHz), and a wide operating temperature range of −55°C to +105°C with a rated endurance of 2000 hours at 105°C.

Key Features

• Electrical Performance — 100 µF capacitance with tolerance −20% to +20%, rated at 16 V and tanδ 0.10 (20°C, 120 Hz).
• Low ESR & High Ripple — ESR specified at 24 mΩ (20°C/100 kHz) and rated ripple currents of 249 mA at 120 Hz and 2.49 A at 300 kHz, supporting both low- and high-frequency applications.
• Compact Radial Package — Miniature φ6.3 × 6 mm can with 2.5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole designs and tight PCB layouts.
• Reliability & Life — Load life specified at 2000 hours at 105°C under rated voltage; leakage current specified at 500 µA (measured after 2 minutes at 20°C).
• Temperature Range — Rated for operation from −55°C to +105°C, suitable for elevated-temperature applications within the specified endurance.
• Manufacturing & Compliance — Radial lead type compatible with lead-free flow soldering conditions and RoHS compliant; available in bulk/bag packing and in mass production status.

Typical Applications

• Power-supply decoupling — Local energy storage and smoothing in DC-DC converters and regulator outputs where low ESR and compact size improve transient response.
• High-frequency filtering — Use in EMI/line-filter stages and high-frequency power circuits that require sustained ripple current handling up to 300 kHz.
• Embedded and compact electronics — Through-hole radial lead form factor for small PCBs that need reliable bulk capacitance in a miniature footprint.

Unique Advantages

• High ripple capability at high frequency: Rated for 2.49 A at 300 kHz, enabling use in demanding HF power sections.
• Low-loss operation: 24 mΩ ESR at 100 kHz and tanδ 0.10 (120 Hz) reduce heat generation and improve efficiency in power circuits.
• Miniature footprint: φ6.3 × 6 mm can with 2.5 mm lead spacing saves PCB area while providing 100 µF bulk capacitance.
• Wide temperature and proven endurance: −55°C to +105°C rating with 2000 h endurance at 105°C supports reliable operation in thermally demanding environments.
• Manufacturing friendly: Radial lead form compatible with lead-free flow soldering and available in bulk/bag packing for volume assembly.
