RKS1C271MCNAJLGS

The RKS1C271MCNAJLGS is a surface-mount conductive‑polymer aluminum solid electrolytic capacitor offering 270 µF capacitance at a 16 V rating. Engineered for general-purpose electronic designs, it combines high ripple capability and low equivalent series resistance (ESR) in a compact SMD can package.

Key value comes from a wide operating range (−55 °C to 125 °C), a long endurance rating (3000 hours at 125 °C), and SMD-friendly packaging that supports standard lead‑free reflow processes.

Key Features

• Capacitance & Tolerance — 270 µF nominal with tolerance of −20% to +20% at 120 Hz, 20 °C.
• Rated Voltage — 16 V DC nominal rating for general-purpose power decoupling and energy storage.
• Conductive‑Polymer Electrolyte — Solid electrolyte construction for stable high-frequency performance.
• Low ESR — ESR of 20 mΩ measured at 20 °C / 100 kHz, supporting efficient high-frequency operation.
• High Ripple Current — Low-frequency ripple current 200 mA (120 Hz) and high-frequency ripple current 2 A (300 kHz), enabling handling of demanding power supply noise and switching currents.
• Loss Angle — tan δ = 0.12 at 20 °C / 120 Hz for controlled dielectric losses.
• Leakage Current — Specified leakage current of 216 µA after application of rated voltage.
• Endurance — Rated load life of 3000 hours at 125 °C under rated voltage.
• Operating Temperature — –55 °C to +125 °C to support harsh thermal environments.
• Package & Assembly — Radial can SMD (φ10 × 12.4L; 1.24 × 1.00 cm), supplied in embossed carrier taping with moisture‑proof packing; compatible with lead‑free reflow to 260 °C per series guidance.
• Polarized — Intended for polarized applications; follow polarity in PCB layout and assembly.

Typical Applications

• Power Supply Decoupling — Bulk and high-frequency decoupling in DC‑DC converters and power modules where low ESR and high ripple handling are needed.
• Switching Regulators — Output filtering for switching power supplies, using the capacitor’s high-frequency ripple capability to reduce voltage ripple.
• Industrial Electronics — Energy storage and smoothing in industrial control and power electronics across a wide temperature range.
• Communications Equipment — Power filtering and decoupling in RF and high-speed digital systems that demand low ESR and stable performance at 100 kHz+ frequencies.

Unique Advantages

• Low ESR for efficient power delivery: 20 mΩ at 100 kHz minimizes losses and improves regulation in high-frequency power circuits.
• High ripple handling: Rated for 2 A at high frequency and 200 mA at 120 Hz, enabling reliable operation under switching and ripple stress.
• Wide temperature and long life: −55 °C to 125 °C operating range with 3000-hour endurance at 125 °C supports demanding thermal and longevity requirements.
• SMD can with reflow compatibility: Radial can SMD form factor supplied in embossed carrier taping and moisture‑proof packing, compatible with lead‑free reflow to 260 °C for modern assembly processes.
• Stable loss characteristics: tan δ of 0.12 at 20 °C / 120 Hz provides predictable dielectric loss for design margin calculations.
