RDS0J271MCNAFEGS

The RDS0J271MCNAFEGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 270 µF capacitance at a 6.3 V rating. It is designed for compact power circuitry where high capacitance, low ESR and reliable high-temperature endurance are required.

Key attributes include low equivalent series resistance (25 mΩ at 100 kHz), high ripple current capability (1.05 A at 300 kHz), and a rated load life of 3000 hours at 125°C. The part is compatible with lead-free reflow soldering (260°C peak) and is RoHS compliant.

Key Features

• Capacitance and Voltage — 270 µF nominal capacitance with a 6.3 V rated voltage and ±20% tolerance.
• Low ESR — 25 mΩ ESR measured at 100 kHz, enabling improved high-frequency performance and reduced loss in power circuits.
• High Ripple Current — Rated ripple current up to 1.05 A at 300 kHz (and 105 mA at 120 Hz), supporting demanding switching regulator and decoupling applications.
• High-Temperature Endurance — Load life rated to 3000 hours at 125°C, with specified limits for capacitance change, tan δ and ESR after endurance testing.
• SMD Package and Reflow Compatible — Radial can SMD package (φD×L: 6.3×5.7 mm) suitable for surface-mount assembly; verified for lead-free reflow peak temperature of 260°C.
• Wide Operating Temperature — Specified operating range from −55°C to +125°C for use across varied thermal environments.
• Standards Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supply Decoupling — Low ESR (25 mΩ at 100 kHz) and 270 µF capacitance make the capacitor effective for decoupling and bulk capacitance on 6.3 V rails in compact power assemblies.
• DC–DC Converters — High ripple current rating (1.05 A at 300 kHz) supports switching regulator output smoothing and input filtering at high switching frequencies.
• Embedded and Industrial Electronics — Long life at elevated temperature (3000 hours at 125°C) and −55°C to +125°C operating range suit extended-temperature boards and embedded systems exposed to high ambient temperatures.
• High-Frequency Filtering — Low ESR and specified ripple-current frequency coefficients enable reliable performance for high-frequency noise suppression in communication and instrumentation modules.

Unique Advantages

• High capacitance in a compact SMD can — 270 µF in a 6.3×5.7 mm package delivers significant energy storage while minimizing board area.
• Reduced thermal and electrical losses — 25 mΩ ESR at 100 kHz lowers dissipation in high-frequency applications, helping maintain regulator stability and thermal margin.
• Designed for high-frequency ripple — Rated ripple current of 1.05 A at 300 kHz and defined frequency coefficients enable predictable behavior across switching frequencies.
• Robust high-temperature life — 3000 hours at 125°C provides a quantifiable reliability metric for long-term deployment in hot operating environments.
• Assembly-ready — Surface-mount radial can and verified lead-free reflow (260°C peak) simplify integration into modern SMT assembly flows.
• Regulatory compliance — RoHS conformity supports use in products requiring restricted-substance compliance.

Why Choose RDS0J271MCNAFEGS?

The RDS0J271MCNAFEGS balances high capacitance, low ESR and strong ripple-current capability in a compact, surface-mount conductive polymer aluminum package. Its 3000‑hour life rating at 125°C and wide −55°C to +125°C operating range make it suitable for designs that must maintain capacitance and ESR stability under thermal stress.

This part is well suited for engineers specifying bulk decoupling or output filtering on low-voltage power rails where predictable high-frequency performance, assembly compatibility with lead-free reflow, and RoHS compliance are required.
