RKS1J150MCNAFGGS

The RKS1J150MCNAFGGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor in the RKS series. It delivers 15 µF capacitance at a 63 V rating in a compact φ6.3 × 7.7 mm SMD can package with polarized terminals and embossed carrier tape packaging.

Designed for applications that demand high ripple tolerance and extended high-temperature endurance, this capacitor offers low ESR, defined leakage characteristics and a 3000 hour load life at 125°C, making it suitable for demanding power-management and high-frequency circuit functions.

Key Features

• Capacitance & Voltage — 15 µF rated capacitance at 63 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Conductive Polymer Electrolyte — Solid-type construction for stable performance with a specified tan δ of 0.12 (20°C, 120 Hz).
• Low ESR — ESR of 80 mΩ measured at 20°C / 100 kHz, supporting efficient high-frequency performance.
• High Ripple Current Capability — Rated ripple current of 90 mA at 120 Hz (low frequency) and 900 mA at 300 kHz (high frequency) for improved decoupling under switching loads.
• Leakage Current — Specified leakage current of 100 µA (note: datasheet specifies leakage ≤ 0.05CV or 100 µA, whichever is greater after 2 minutes’ application of rated voltage).
• Extended High‑Temperature Endurance — Load life of 3000 hours at 125°C under rated voltage; rated operating temperature range −55°C to +125°C.
• SMD Can Package & Reflow Compatible — Radial can SMD package (φ6.3 × 7.7 mm) supplied in embossed carrier tape with moisture-proof packing; compatible with lead‑free reflow profiles (peak up to 260°C as per series specification).
• RoHS Compliant — Conforms to RoHS requirements as indicated in the product documentation.

Typical Applications

• Switching power supplies and DC‑DC converters — Low ESR and high allowable ripple current make this part suitable for bulk decoupling and output filter duties in switching regulators.
• Power management modules — Compact SMD can package and sustained high-temperature endurance support use in power management assemblies exposed to elevated operating temperatures.
• High-frequency decoupling — Specified ESR at 100 kHz and high-frequency ripple current rating enable effective decoupling in high-frequency circuits.

Unique Advantages

• High ripple-handling capability: 900 mA at 300 kHz (high-frequency) and 90 mA at 120 Hz (low-frequency) provide margin for switching applications and load transients.
• Stable high-temperature performance: 3000 hour life at 125°C supports long-term reliability in elevated-temperature environments.
• Low AC losses: tan δ of 0.12 (20°C, 120 Hz) and 80 mΩ ESR (100 kHz) reduce heating and improve efficiency in high-frequency operation.
• Compact SMD form factor: φ6.3 × 7.7 mm can package in embossed carrier tape enables automated placement and space-efficient PCB layouts.
• Predictable leakage behavior: Leakage specifications (≤ 0.05CV or 100 µA, whichever is greater) support reliable biasing and hold-up performance in circuits.
• Supply chain readiness: Mass-production status with moisture-proof tape packing simplifies procurement and assembly handling.
