RKS1H680MCNAHJGS

The RKS1H680MCNAHJGS is a surface-mount conductive polymer aluminum electrolytic capacitor offering 68 µF capacitance at 50 V. Designed for general-purpose SMD applications, it combines low ESR and high allowable ripple current with extended load life for demanding temperature environments.

Key value propositions include low equivalent series resistance (30 mΩ at 100 kHz), high-frequency ripple capability (1.25 A at 300 kHz), and proven endurance (3000 hours at 125°C), making it suitable where stable performance and thermal robustness are required.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a rated voltage of 50 V and tolerance of −20% to +20%.
• Low ESR — ESR of 30 mΩ measured at 20°C and 100 kHz, enabling efficient high-frequency performance and reduced losses.
• High Ripple Current — Rated ripple current of 125 mA at 120 Hz and 1.25 A at 300 kHz for robust handling of AC stress in power circuits.
• Wide Temperature & Long Life — Operating range from −55°C to 125°C with an endurance rating of 3000 hours at 125°C under rated voltage.
• Dielectric Loss (tan δ) — tanδ of 0.12 measured at 20°C, 120 Hz to indicate loss characteristics under standard test conditions.
• SMD Can Package — Radial, can-style SMD package with dimensions φ8 × 10 mm (D: 0.8 cm, L: 1.0 cm) and embossed carrier tape packaging with moisture-proof packing.
• Leakage Current — Specified leakage current of 170 µA, measured after standard conditioning.
• Compliance — RoHS compliant.

Typical Applications

• General-purpose SMD designs — Suitable for a wide range of surface-mount circuits that require a compact 68 µF, 50 V polarized capacitor.
• High-frequency and high-ripple circuits — Used where elevated high-frequency ripple currents are present, leveraging its 1.25 A rating at 300 kHz and low ESR.
• High-temperature environments — Appropriate for applications that must withstand elevated operating temperatures, supported by a −55°C to 125°C range and 3000-hour endurance at 125°C.

Unique Advantages

• Extended high-temperature endurance: 3000 hours at 125°C provides predictable aging and reliability in thermally demanding designs.
• High-frequency efficiency: 30 mΩ ESR at 100 kHz and low dielectric loss (tanδ 0.12) reduce dissipation and improve performance in switching environments.
• Robust ripple handling: 1.25 A at 300 kHz and 125 mA at 120 Hz allow the capacitor to tolerate significant AC stress without performance degradation.
• Compact SMD form factor: φ8 × 10 mm can-style package minimizes board area while providing the benefits of a solid polymer electrolyte capacitor.
• Production-ready packaging: Supplied in embossed carrier tape with moisture-proof packing for streamlined assembly and handling.
• Regulatory compliance: RoHS-compliant construction supports environmentally conscious product designs.
