RKS1H220MCNAHJGS

The RKS1H220MCNAHJGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor rated at 22 µF and 50 V. It combines low equivalent series resistance and high allowable ripple current in a compact φ8 × 10 mm SMD can for general-purpose electronic designs.

Designed for robust operation across a wide temperature range (−55 °C to 125 °C) and a load life of 3000 hours at 125 °C, this part targets applications that require stable capacitance, low loss (tan δ = 0.12 at 20 °C, 120 Hz), and long-term reliability under elevated temperature stress.

Key Features

• Capacitance & Voltage — 22 µF rated capacitance with a 50 V working voltage and ±20% tolerance at 20 °C, 120 Hz, suitable for a range of power and decoupling needs.
• Low Loss / Low ESR — Specified DF (tan δ) of 0.12 and ESR of 30 mΩ at 20 °C, 100 kHz, enabling efficient high-frequency performance and reduced dissipation.
• High Allowable Ripple Current — Low-frequency ripple current of 125 mA (120 Hz) and high-frequency ripple current of 1.25 A (300 kHz) to support demanding ripple environments.
• Long Life & Wide Temperature Range — Rated lifetime of 3000 hours at 125 °C and an operating temperature range from −55 °C to 125 °C for extended reliability in thermally stressful conditions.
• Leakage & Reliability — Leakage current specified as 100 µA, with endurance and shelf-life characteristics established in the datasheet (including post-125 °C and 85 °C/85% RH tests).
• SMD Can Package & Assembly — Radial can SMD package (φ8 × 10 mm) in embossed carrier taping with moisture-proof packing and compatibility with lead-free reflow soldering (peak 260 °C per datasheet conditions).
• Regulatory — RoHS compliant for lead-free product handling and assembly environments.

Typical Applications

• General Purpose Electronics — Intended for general-purpose use where a 22 µF, 50 V SMD capacitor with low ESR and high ripple capability is required.
• Power Stage Support — Suited to board-level power sections that demand stable capacitance and high allowable ripple current within the stated temperature and lifetime specifications.
• High-Temperature Environments — Ideal for designs that require sustained operation up to 125 °C and validated load life of 3000 hours at that temperature.

Unique Advantages

• Low ESR at High Frequency: ESR specified at 30 mΩ (100 kHz) reduces losses and heat in high-frequency circuits.
• High Ripple Handling: Rated for 1.25 A ripple at 300 kHz and 125 mA at 120 Hz, enabling use in applications with significant AC stress on capacitors.
• Extended Thermal Endurance: 3000-hour life at 125 °C provides long-term stability for thermally demanding systems.
• SMD Can with Reflow Compatibility: φ8 × 10 mm radially packaged SMD can shipped in embossed carrier tape and moisture-proof packing, supporting lead-free reflow (260 °C peak) per datasheet guidance.
• Controlled Leakage and Loss: Leakage current spec of 100 µA and tan δ of 0.12 (20 °C, 120 Hz) support predictable behavior in power and timing circuits.
• RoHS Compliant: Meets RoHS requirements for lead-free assembly environments.
