RKS1V390MCNAHFGS

The RKS1V390MCNAHFGS is a surface-mount conductive polymer aluminum electrolytic capacitor offering 39 µF capacitance at a 35 V rating. It combines low equivalent series resistance and high allowable ripple current in a compact φ8 × 6.7 mm can-style SMD package designed for reflow assembly.

Engineered for applications that require stable performance across a wide temperature range, this RoHS-compliant capacitor delivers long endurance (3000 hours at 125°C) and tightly controlled electrical characteristics for power management, decoupling and bulk energy storage in compact electronic designs.

Key Features

• Conductive polymer aluminum construction  Solid electrolyte design for stable electrical characteristics and reduced ESR compared with conventional wet electrolytics.
• Capacitance and tolerance  39 µF with ±20% tolerance (measured at 20°C, 120 Hz) for predictable bulk and decoupling behavior.
• Voltage rating  Rated for 35 V operation to support mid-voltage power rails and converters.
• Low ESR  30 mΩ specified at 20°C, 100 kHz, enabling efficient high-frequency filtering and reduced power loss.
• High ripple current capability  160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) to handle dynamic loads and switching currents.
• Wide operating temperature  Specifically rated from −55°C to 125°C, with endurance verified for 3000 hours at 125°C under rated voltage.
• Leakage and dissipation  Leakage current specified at 100 µA and tan δ of 0.12 (20°C, 120 Hz), supporting controlled loss and low standby dissipation.
• SMD package and assembly  φ8 × 6.7 mm radial can-style SMD with embossed carrier taping and moisture-proof packing; compatible with lead-free reflow profiles up to 260°C peak per the series soldering guidelines.
• Reliability and shelf life  Endurance and shelf-life conditions from the series specification: capacitance, tan δ and ESR remain within defined limits after endurance, damp heat and soldering heat tests.

Typical Applications

• Power supply decoupling  Low ESR and high high-frequency ripple capability make this part suitable for decoupling on switching regulators and intermediate rails.
• DC–DC converters  Compact 35 V rating and 39 µF capacitance provide bulk smoothing and transient support in board-level converters.
• Point-of-load filtering  High allowable ripple current and low ESR help stabilize local power rails in densely packed electronics.

Unique Advantages

• High ripple tolerance: 1.6 A high-frequency ripple current rating at 300 kHz reduces thermal stress and extends system reliability under dynamic load conditions.
• Low ESR for efficient filtering: 30 mΩ ESR at 100 kHz minimizes voltage drop and power loss across the capacitor in high-speed switching environments.
• Wide temperature endurance: Rated −55°C to 125°C with 3000 hours life at 125°C, supporting designs that require sustained performance at elevated temperatures.
• Surface-mount convenience: Embossed carrier taping and moisture-proof packing streamline automated assembly and inventory handling.
• Controlled leakage and loss: Leakage current spec (100 µA) and tan δ (0.12 at 20°C, 120 Hz) enable predictable standby behavior and thermal management.
