RF80J271MDN1

The RF80J271MDN1 is a conductive polymer aluminum solid electrolytic capacitor intended for general-purpose electronic applications. It combines low ESR/ESL construction with high ripple-current capability to support demanding power-decoupling and high-frequency smoothing tasks.

Key attributes include a 270 µF capacitance at 6.3 V, a wide operating temperature range from −55 °C to 105 °C, and a long load life specification of 2000 hours at 105 °C, all in a radial lead, φ5 can footprint suitable for through-hole assemblies.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance at 6.3 V with ±20% tolerance, suitable for bulk decoupling and smoothing in low-voltage power rails.
• Low ESR / Low ESL — ESR specified at 11 mΩ (100 kHz, 20 °C) and typ. ESL 1.5 nH, enabling reduced loss and improved high-frequency performance.
• High Ripple Current — Rated ripple current of 370 mA at 120 Hz and 3.7 A at 300 kHz, supporting both low- and high-frequency switching environments.
• Thermal and Lifetime Performance — Operating range −55 °C to 105 °C with a rated load life of 2000 hours at 105 °C for reliable elevated-temperature operation.
• Polarized Radial Lead Package — Radial lead (can) package with 2.0 mm lead spacing, compatible with lead-free flow soldering processes.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply decoupling — Use as bulk or output capacitors on low-voltage DC–DC converters where low ESR and high ripple handling are required.
• High-frequency switching circuits — Suited for smoothing and ripple suppression in switch-mode power supplies up to hundreds of kHz, supported by specified ripple current at 300 kHz.
• General purpose electronics — Through-hole radial lead format fits conventional assembly flows for consumer and industrial electronics needing reliable polymer capacitor performance.

Unique Advantages

• Reduced power loss: Low ESR (11 mΩ at 100 kHz) minimizes dissipation under ripple conditions, improving efficiency in power stages.
• High-frequency capability: Specified ripple current up to 3.7 A at 300 kHz and low ESL (typ. 1.5 nH) support compact decoupling near fast switching devices.
• Durable at elevated temperature: 2000-hour load life at 105 °C provides predictable end-of-life behavior for designs exposed to higher ambient temperatures.
• Assembly-ready radial format: Radial lead construction with lead-free flow soldering compatibility simplifies integration into through-hole assemblies.
• Regulatory confidence: RoHS compliance ensures alignment with common restriction-of-hazardous-substance requirements.
