RNE1A221MDS1

The RNE1A221MDS1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, offering 220 µF capacitance at a 10 V rating. It is designed for general-purpose circuit use where low ESR, high ripple current capability, and a compact radial package are required.

Targeted at general-purpose electronic designs, this component delivers a combination of low equivalent series resistance, wide operating temperature range, and long endurance for reliable board-level decoupling and power-filtering applications.

Key Features

• Conductive polymer aluminum solid electrolyte — Solid electrolyte construction for stable capacitance and low-loss performance in compact radial packages.
• 220 µF, 10 V rating — Provides bulk capacitance for decoupling and power rail stabilization in 10 V systems with ±20% tolerance.
• Low ESR — ESR of 30 mΩ measured at 20°C/100 kHz, enabling improved high-frequency performance and reduced power dissipation.
• High ripple current capability — Rated ripple current of 250 mA at 120 Hz and 2.5 A at 300 kHz supports both low- and high-frequency ripple handling.
• Wide operating temperature — −55°C to 105°C operating range suitable for a broad set of environmental conditions.
• Defined endurance — Load life specification of 2000 hours at 105°C for predictable long-term performance.
• Compact radial can — Case size φ6.3×10 mm with 2.5 mm lead spacing (±0.5 mm) for through-hole board mounting and straightforward assembly.
• Leakage and dissipation specs — Leakage current of 440 µA and tanδ of 0.08 (20°C, 120 Hz) for predictable loss characteristics.
• RoHS compliant and mass production — Environmentally compliant product available in bulk and bag packing with production status listed as mass production.

Typical Applications

• Power supply decoupling — Bulk and high-frequency decoupling on DC/DC converters and linear regulators where 220 µF and low ESR reduce voltage ripple.
• Board-level power filtering — Smoothing and filtering in general-purpose electronic assemblies benefiting from high ripple current at kHz frequencies.
• Embedded systems — General-purpose energy storage and transient support in consumer and industrial embedded designs across −55°C to 105°C.

Unique Advantages

• Low-loss operation: 30 mΩ ESR at 100 kHz minimizes dissipation and supports efficient high-frequency filtering.
• High ripple tolerance: Rated for 2.5 A at 300 kHz, enabling use in high-frequency power stages and switching regulators.
• Compact, assembly-friendly package: φ6.3×10 mm radial can with 2.5 mm lead spacing simplifies through-hole mounting and placement.
• Wide temperature range and defined life: −55°C to 105°C with 2000 hours endurance at 105°C provides predictable long-term behavior in demanding environments.
• Predictable leakage and dissipation: Specified leakage current (440 µA) and tanδ (0.08) support reliable power budgeting and thermal design.
• RoHS-compliant and production-ready: Available in bulk or bag packing with mass production status for volume designs.
