RNS1C220MDS1

The RNS1C220MDS1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, offering 22 µF nominal capacitance at 16 V. Designed for general-purpose electronic applications, it delivers a compact footprint and measurable low ESR and leakage characteristics for board-level power applications.

Its specification set — including a wide operating temperature range and rated endurance — makes it suitable for designs that require stable capacitance, defined ripple-handling, and predictable electrical performance over time.

Key Features

• Core Electrical — 22 µF capacitance at 16 V with tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Low Loss / High-Frequency Performance — tan δ = 0.06 (20°C, 120 Hz) and ESR = 49 mΩ measured at 20°C/100 kHz, supporting high-frequency applications.
• Ripple Current Capability — Rated low-frequency ripple current of 190 mA at 120 Hz and high-frequency ripple current of 1.9 A at 300 kHz (frequency coefficient data available in series datasheet).
• Leakage Current — Low leakage current specified at 52 µA after application of rated voltage.
• Reliability / Endurance — 2000 hours endurance at 105°C under rated voltage conditions per the RNS series specification.
• Temperature Range — Rated for operation from -55°C to 105°C.
• Package & Mounting — Compact radial lead can: φ6.3 × 7 mm, lead spacing 2.5 mm (tolerance 0.5 mm); available in bulk (no terminal forming) or bag packing.
• Polarized — Designed as a polarized electrolytic capacitor for appropriate circuit use.

Typical Applications

• General-purpose electronics — For circuits that specify a 22 µF, 16 V conductive polymer radial electrolytic capacitor in a compact can package.
• Board-level power modules — Suitable where defined ESR and ripple current ratings at 100 kHz–300 kHz are required for performance verification.
• Space-constrained designs — Compact φ6.3 × 7 mm can and 2.5 mm lead spacing for tight PCB layouts.

Unique Advantages

• Low ESR at high frequency: 49 mΩ (20°C/100 kHz) supports high-frequency ripple handling and predictable impedance behavior.
• High-frequency ripple capability: Rated for 1.9 A ripple current at 300 kHz, enabling use in applications with significant HF ripple content.
• Wide operating temperature range: −55°C to 105°C supports deployment across a broad set of environmental conditions.
• Defined endurance: 2000 hours at 105°C provides a known life expectation for thermal stress conditions.
• Compact radial can: φ6.3×7 mm footprint and 2.5 mm lead spacing reduce PCB area while retaining through-hole mounting robustness.
• Low leakage: Specified leakage current of 52 µA after rated-voltage application aids in low-standby-current designs.
