RKS1E221MCNAHJGS

The RKS1E221MCNAHJGS is a surface-mount conductive polymer aluminum electrolytic capacitor in Nichicon’s RKS series, offering 220 µF capacitance at a 25 V rating. It is a polarized SMD radial-can style capacitor designed for general-purpose electronic use where bulk capacitance, low equivalent series resistance, and high ripple handling are required.

Key value propositions include a low ESR of 27 mΩ (measured at 20°C/100 kHz), high frequency ripple capability up to 1.6 A, and an extended load life of 3000 hours at 125°C, providing robustness for demanding thermal and ripple environments.

Key Features

• Dielectric / Construction  Conductive polymer aluminum solid electrolytic construction tailored for low loss and stable performance.
• Nominal Capacitance  220 µF with tolerance −20% to +20% at 120 Hz, 20°C.
• Rated Voltage  25 V DC.
• Low Loss / ESR  ESR of 27 mΩ at 20°C/100 kHz, supporting efficient high-frequency operation.
• Ripple Current Capability  Low-frequency ripple 160 mA (120 Hz) and high-frequency ripple 1.6 A (300 kHz) for effective smoothing and decoupling under dynamic loads.
• Leakage Current  Specified leakage current of 275 µA after initial conditions.
• High Temperature Endurance  Rated for a lifetime of 3000 hours at 125°C under rated voltage.
• Wide Operating Temperature  −55°C to +125°C operating range for broad environmental tolerance.
• Package & Assembly  φ8 × 10 mm radial can SMD (embossed carrier taping and moisture-proof packing). Compatible with lead‑free reflow soldering peak temperatures up to 260°C as defined in the series datasheet.
• Compliance  The series documentation states compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose electronics  Bulk energy storage and smoothing where a compact 220 µF, 25 V polarized SMD capacitor is required.
• Power supply filtering  Low ESR and high ripple current capability make it suitable for smoothing and output filtering in power modules and converters.
• High‑temperature environments  Endurance rating of 3000 hours at 125°C supports use in designs exposed to elevated ambient temperatures.

Unique Advantages

• High ripple tolerance: The combination of 1.6 A high-frequency ripple capability and 27 mΩ ESR reduces heating and improves stability under dynamic load conditions.
• Extended life at elevated temperature: 3000 hours endurance at 125°C provides predictable lifetime behavior for thermal stress applications.
• Compact SMD radial-can form factor: φ8 × 10 mm size and embossed carrier taping support automated placement while delivering 220 µF in a small footprint.
• Low-loss dielectric: Conductive polymer construction with tanδ = 0.12 (20°C, 120 Hz) helps maintain performance across frequency and temperature.
• Manufacturing-friendly: Documented compatibility with lead‑free reflow up to 260°C facilitates modern assembly processes.
• RoHS‑aligned: Series-level RoHS compliance reduces regulatory handling and supports green-design efforts.
