RKS1E220MCNAHGGS

The RKS1E220MCNAHGGS is a surface‑mount conductive‑polymer aluminum solid electrolytic capacitor in a compact φ8 × 7.7 mm can. It delivers low equivalent series resistance (ESR) and high allowable ripple current for demanding power and high‑frequency decoupling applications.

Designed for elevated‑temperature operation and reflow assembly, this RoHS‑compliant capacitor provides a combination of low ESR, high ripple capability, and extended load life (3000 hours at 125°C) for stable performance in harsh thermal environments.

Key Features

• Dielectric / Construction Conductive‑polymer aluminum solid electrolyte for improved high‑frequency performance and reliability.
• Capacitance & Tolerance 22 µF capacitance with ±20% tolerance (120 Hz, 20°C).
• Rated Voltage 25 V nominal rating.
• Low ESR & Loss Tangent ESR 30 mΩ measured at 100 kHz, 20°C, and tanδ 0.12 (20°C, 120 Hz) for efficient filtering at high switching frequencies.
• High Ripple‑Current Capability Rated ripple current: 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency).
• Thermal Endurance Wide operating temperature range of −55°C to +125°C with load life of 3000 hours at 125°C under rated voltage.
• SMD Assembly & Packaging Surface‑mount radial can package (φ8 × 7.7 mm) compatible with lead‑free reflow (peak up to 260°C) and supplied in embossed carrier taping with moisture proof packing.
• Leakage & Polarization Polarized construction with specified leakage current up to 100 µA.
• Regulatory Status RoHS compliant.

Typical Applications

• Power conversion and DC‑DC converters Bulk smoothing and output decoupling where low ESR and high ripple handling improve regulator stability and efficiency.
• High‑frequency switching regulators Decoupling at switching frequencies thanks to low ESR at 100 kHz and a 1.6 A high‑frequency ripple rating.
• Industrial and telecommunications equipment Support for elevated operating temperatures (−55°C to 125°C) and long life under thermal stress.
• Compact SMD power modules Small φ8 × 7.7 mm can for space‑constrained board designs with tape‑and‑reel packaging for automated placement.

Unique Advantages

• Low ESR for improved transient response: 30 mΩ at 100 kHz reduces voltage ripple and supports tight regulation in switching supplies.
• High ripple‑current capability: Dual ripple ratings (160 mA at 120 Hz, 1.6 A at 300 kHz) cover both low‑ and high‑frequency noise environments.
• Extended high‑temperature life: 3000 hours at 125°C under rated voltage delivers predictable aging and robustness in thermal stress scenarios.
• Reflow‑compatible SMD form factor: Designed for lead‑free reflow (up to 260°C peak) and supplied in embossed carrier taping for automated assembly.
• Clear specification set for engineering verification: Defined tanδ, leakage current, ESR, ripple current, and life ratings simplify component selection and qualification.
