RKS1J560MCNAJJGS

The RKS1J560MCNAJJGS is a surface-mount conductive-polymer aluminum electrolytic capacitor from Nichicon’s RKS series. It delivers 56 µF capacitance at a 63 V rating in a compact φ10 × 10 mm SMD can, designed for general-purpose power electronics that require high ripple handling and long-term stability.

With a −55 °C to 125 °C operating range and a rated life of 3000 hours at 125 °C, this part targets designs that demand reliable, low-ESR energy storage and decoupling across demanding thermal and frequency conditions.

Key Features

• Core Electrical — 56 µF capacitance at 63 V with tolerance −20% to 20%, providing predictable energy storage for power rails and bulk decoupling.
• Low ESR — 30 mΩ ESR measured at 100 kHz (20 °C), enabling efficient high-frequency performance and reduced thermal dissipation.
• High Ripple Capability — Low-frequency ripple current 140 mA (120 Hz) and high-frequency ripple current 1.4 A (300 kHz), supporting both bulk smoothing and high-frequency switching applications.
• Leakage and Loss — Specified leakage current of 176 µA and tan δ (DF) of 0.12 (20 °C, 120 Hz), allowing predictable loss and standby behavior in power circuits.
• Wide Temperature & Long Life — Operating range −55 °C to 125 °C with a rated lifetime of 3000 hours at 125 °C, suitable for extended high-temperature operation.
• Surface-Mount Can Package — φ10 × 10 mm radial SMD can in embossed carrier taping with moisture-proof packing for automated placement and reliable board assembly.
• RoHS Compliant — Meets RoHS directive requirements as provided in the product data.
• Reflow Compatibility — SMD type supports lead-free reflow soldering per datasheet guidance (peak 260 °C allowed under specified time limits).

Typical Applications

• Power Supply Filtering — Bulk smoothing and filter capacitors on 63 V rails where low ESR and measurable leakage are required for stable voltage supply.
• DC–DC Converter Output — Output decoupling for switching regulators that benefit from low ESR (30 mΩ at 100 kHz) and high-frequency ripple tolerance up to 1.4 A.
• High-Frequency Power Rail Decoupling — Local decoupling on high-frequency power rails where both low-loss (tan δ 0.12) and compact SMD packaging are important.

Unique Advantages

• High ripple handling in a compact SMD can: 1.4 A high-frequency ripple current capability with 30 mΩ ESR provides efficient decoupling in tight board space.
• Wide temperature resilience: Rated for −55 °C to 125 °C operation and 3000-hour life at 125 °C for sustained high-temperature reliability.
• Predictable leakage and loss characteristics: Specified leakage current (176 µA) and tan δ (0.12 at 120 Hz) allow designers to budget standby losses and thermal rise accurately.
• SMD-ready packaging: Embossed carrier taped, moisture-proof packing and lead-free reflow compatibility streamline high-volume assembly.
• RoHS compliance: Environmentally compliant material selection simplifies regulatory considerations for many markets.
