RNS1A101MDN1

The RNS1A101MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial‑lead can designed for general‑purpose electronic applications. It delivers 100 µF capacitance at a 10 V rating with a compact φ8×11.5 mm package and 3.5 mm lead spacing.

Engineered for power-handling and high-frequency ripple environments, this part combines a low ESR of 21 mΩ (20°C/100 kHz) with high rated ripple current and a wide operating temperature range of -55°C to 105°C for reliable operation in demanding designs.

Key Features

• Capacitance & tolerance — 100 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• Rated voltage — 10 V rated voltage with 11.5 V surge per the RNS series designation.
• Low ESR for high‑frequency use — 21 mΩ equivalent series resistance measured at 20°C/100 kHz, supporting stable performance at high switching frequencies.
• High ripple current capability — Rated ripple current 390 mA at 120 Hz and 3.9 A at 300 kHz (frequency coefficient data available in the series specification).
• Temperature and endurance — Operating range -55°C to 105°C with 2000 hours endurance at 105°C under rated voltage conditions.
• Leakage current — Specified leakage current of 150 µA (after 2 minutes at rated voltage, 20°C condition described in the datasheet).
• Compact radial package — φ8×11.5 mm can, radial lead mounting, lead spacing 3.5 mm ±0.5 mm; supplied in bulk/bag packing for mass production.
• Polarized design — Polarized aluminum solid electrolytic capacitor suitable for DC power circuits.

Typical Applications

• General-purpose power circuitry — Energy storage and smoothing in general-purpose electronic designs requiring compact radial electrolytics.
• High-frequency power stages — Filtering and ripple handling where low ESR at 100 kHz and rated high‑frequency ripple current are required.
• DC/DC converters and point‑of‑load — Local decoupling and bulk support for converters operating up to the specified temperature and frequency ranges.

Unique Advantages

• Low ESR at switching frequencies — 21 mΩ (20°C/100 kHz) supports reduced voltage ripple and thermal dissipation in high-frequency circuits.
• High-frequency ripple capability — Rated ripple current of 3.9 A at 300 kHz enables use in demanding switching applications without exceeding specified limits.
• Wide temperature endurance — -55°C to 105°C operating range with 2000 h endurance at 105°C provides durability for long-term deployments.
• Compact radial form factor — φ8×11.5 mm can with 3.5 mm lead spacing simplifies replacement of through-hole electrolytics while saving board area.
• Predictable leakage and stability — Specified leakage current (150 µA) and series ESR measurement methodology from the datasheet enable easier thermal and reliability planning.
