RKS1J220MCNAHGGS

The RKS1J220MCNAHGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor rated at 22 µF and 63 V. It combines low ESR and high allowable ripple current with extended high-temperature endurance for compact power and high-frequency SMD designs.

Key attributes include a wide operating temperature range (−55 °C to 125 °C), a 3000-hour life at 125 °C, and lead-free reflow compatibility to 260 °C, making it suitable for assemblies that demand thermal reliability and reliable filtering under elevated stress.

Key Features

• Capacitance and Voltage — 22 µF nominal capacitance with a rated voltage of 63 V and capacitance tolerance of −20% to +20% (measured at 20 °C, 120 Hz).
• Conductive Polymer Dielectric — Solid polymer construction for stable electrical characteristics and reduced equivalent series resistance compared to traditional wet electrolytics.
• Low ESR & High Frequency Performance — ESR specified at 40 mΩ measured at 20 °C/100 kHz, optimized for high-frequency ripple handling.
• High Allowable Ripple Current — Low-frequency ripple current 110 mA (120 Hz) and high-frequency ripple current 1.1 A (300 kHz), supporting demanding power decoupling tasks.
• High-Temperature Endurance — Rated life of 3000 hours at 125 °C under rated voltage, with operating range from −55 °C to 125 °C.
• Leakage and Loss — Leakage current up to 100 µA and tan δ (DF) of 0.12 (measured at 20 °C, 120 Hz), enabling predictable loss and standby behavior.
• Surface-Mount Can Package — Radial can SMD package with dimensions φ8 × 7.7 mm and SMD land recommendation 8.3 × 8.3 mm; delivered in embossed carrier taping with moisture-proof packing for automated assembly.
• Reflow Compatibility & Marking — Compatible with lead-free reflow peak temperatures (260 °C) per the datasheet profile; case top marked with navy blue print.
• RoHS Compliant — Conforms to RoHS requirements as stated in the product information.

Typical Applications

• High-frequency power circuits — Low ESR at 100 kHz and 1.1 A high-frequency ripple current make this capacitor suitable for AC ripple suppression and decoupling in switching regulators and power modules.
• High-temperature electronics — 3000-hour life at 125 °C and an operating range down to −55 °C support use in industrial and thermally demanding environments.
• Surface-mount power assemblies — Compact φ8 × 7.7 mm SMD can and embossed carrier taping enable automated placement in dense board layouts requiring robust bulk capacitance.

Unique Advantages

• Low ESR for improved ripple performance — 40 mΩ ESR at 100 kHz reduces voltage drop and heating under dynamic loads, improving power-stage efficiency.
• High ripple-current handling — 1.1 A at high frequency and 110 mA at low frequency accommodate a wide range of switching and linear ripple conditions.
• Extended high-temperature life — 3000 hours at 125 °C provides long-term reliability in elevated-temperature systems and reduces maintenance/replacement cycles.
• SMD-friendly packaging — Embossed carrier tape and moisture-proof packing simplify integration into automated assembly while supporting lead-free reflow processes.
• Predictable leakage and loss characteristics — Specified leakage current (100 µA) and tan δ (0.12 at 20 °C, 120 Hz) enable predictable design margins for standby and filtering applications.
• RoHS compliant — Meets environmental requirements for lead-free production environments.
