RNS1D220MDS1

The RNS1D220MDS1 is a conductive polymer aluminum solid electrolytic capacitor in a compact radial-lead can (φ6.3×7 mm). It offers a 22 µF capacitance at a 20 V rating with polarized radial mounting for general-purpose electronic designs.

Engineered for applications that require low ESR and robust high‑frequency ripple handling, this part delivers measured electrical characteristics suitable for compact assemblies across a wide temperature range and a specified endurance at elevated temperature.

Key Features

• Core Technology  Conductive polymer aluminum solid electrolyte construction as part of the RNS series.
• Capacitance & Voltage  22 µF capacitance with a 20 V rated voltage and tolerance of −20% to +20%.
• Low Loss / DF  tanδ = 0.06 (measured at 20°C, 120 Hz), supporting stable AC behavior under the specified measurement conditions.
• Low ESR & High‑Frequency Performance  ESR = 49 mΩ at 20°C / 100 kHz and rated high‑frequency ripple current of 1.9 A at 300 kHz, enabling effective performance in higher-frequency circuits.
• Ripple Current  Low‑frequency ripple current: 190 mA at 120 Hz; high‑frequency ripple current: 1.9 A at 300 kHz (frequency coefficients per series data apply).
• Leakage Current  Specified leakage current: 66 µA (measurement conditions noted in product data).
• Temperature & Endurance  Operating temperature range −55°C to +105°C with an endurance rating of 2000 hours at 105°C.
• Package & Mounting  Radial lead can, size φ6.3×7 mm with 2.5 mm lead spacing (±0.5 mm). Available bulk (no terminal forming) or bag packing.

Typical Applications

• General Purpose Electronics  Suitable for general-purpose boards and modules that specify a 22 µF, 20 V polarized capacitor in a radial-lead package.
• High‑Frequency Circuits  Applicable where measured ESR (49 mΩ at 100 kHz) and high‑frequency ripple current capability (1.9 A at 300 kHz) are required.
• Temperature‑Challenged Systems  Designed for use across −55°C to 105°C with defined endurance (2000 h at 105°C) for sustained elevated‑temperature operation.

Unique Advantages

• Compact, board‑friendly form factor  φ6.3×7 mm radial can minimizes PCB area while providing axial lead mounting with 2.5 mm spacing.
• Measured low ESR at 100 kHz  49 mΩ ESR (20°C/100 kHz) supports reduced AC voltage drop and improved performance in high‑frequency paths.
• High‑frequency ripple capability  Rated 1.9 A ripple at 300 kHz delivers usable ripple handling for elevated switching frequencies (series frequency coefficients apply).
• Extended thermal endurance  2000 hours at 105°C specified endurance offers predictable aging characteristics for long‑life designs.
• Controlled leakage and loss  Specified leakage current (66 µA) and tanδ (0.06 at 20°C/120 Hz) provide quantifiable parameters for power budgeting and AC loss calculations.
• Standardized packaging options  Available in bulk (no terminal forming) or bag packing to suit assembly and handling preferences.
