RKS1V270MCNAHFGS

The RKS1V270MCNAHFGS is a surface-mount conductive polymer aluminum electrolytic capacitor from Nichicon's RKS series. It delivers 27 µF capacitance at 35 V with low ESR and high allowable ripple capability in a compact φ8 × 6.7 mm SMD can.

Designed for demanding thermal and ripple environments, this capacitor targets SMD power applications that require stable capacitance and long endurance up to 125°C, backed by a 3000-hour life specification at rated temperature.

Key Features

• Capacitance & Tolerance — 27 µF nominal with a tolerance of −20% to +20% at 120 Hz, 20°C.
• Rated Voltage — 35 V working voltage suitable for mid-voltage power rails.
• Low Loss / Frequency Performance — tan δ = 0.12 measured at 20°C, 120 Hz to characterize dielectric losses.
• Low ESR — ESR specified at 30 mΩ (measured at 100 kHz, 20°C) to support low-impedance filtering and high-frequency decoupling.
• High Ripple Current Capability — 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) for applications with significant AC stress.
• Leakage Current — Specified leakage current up to 100 µA (or 0.05CV, whichever is greater) after standard conditioning.
• Extended High-Temperature Endurance — Rated life of 3000 hours at 125°C under rated voltage.
• Robust Temperature Range — Operating from −55°C to +125°C for wide thermal margin.
• Surface-Mount Can Package — Radial can SMD form factor (φ8 × 6.7 mm) with recommended PCB land size 8.3 × 8.3 mm; supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Lead-Free Reflow Compatible — SMD type designed for lead-free reflow soldering with a 260°C peak correspondence as specified for the series.
• RoHS Compliant — Conforms to RoHS requirements.

Typical Applications

• Power supply output filtering — Low ESR (30 mΩ) and 1.6 A high-frequency ripple current capability make this capacitor suitable for smoothing and stabilizing DC-DC converter outputs.
• Point-of-load decoupling — Compact SMD can and strong high-frequency performance support decoupling close to regulators and power ICs where board space is limited.
• Telecommunications and networking equipment — Extended temperature range (−55°C to +125°C) and 3000-hour endurance at 125°C provide reliability for rack-mounted and field-deployed power systems.

Unique Advantages

• High ripple handling in a small footprint: 1.6 A high-frequency ripple current and 30 mΩ ESR deliver effective ripple absorption without large electrolytic volume.
• Extended thermal endurance: Specified 3000-hour life at 125°C supports long-term reliability in high-temperature operating environments.
• Predictable leakage behavior: Leakage current defined as 100 µA (or 0.05CV), enabling designers to budget standby losses and bias bleed requirements accurately.
• Assembly-ready packaging: Embossed carrier taping with moisture-proof packing and lead-free reflow compatibility simplify automated SMD production flows.
• Measured, verifiable performance: Key parameters (tan δ, ESR, ripple current) are specified with measurement conditions for straightforward electrical validation in designs.

Why Choose RKS1V270MCNAHFGS?

The RKS1V270MCNAHFGS balances compact SMD packaging with low ESR, high ripple current capability, and extended high-temperature life, making it a practical choice for power-dense designs that require reliable filtering and decoupling.
