PLF1E470MDO2

The PLF1E470MDO2 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can package, designed for demanding thermal and ripple-current environments. With a rated capacitance of 47 µF and 25 V rating, it offers low ESR and high ripple-current capability suitable for automotive and other high-reliability power designs.

Key design attributes include AEC-Q200 qualification, RoHS compliance, an operating temperature range of -55 °C to 105 °C, and a rated load life of 2000 hours at 105 °C—delivering durable performance where thermal endurance and stable electrical characteristics matter.

Key Features

• Electrical Performance: 47 µF capacitance at 25 V with ±20% tolerance, polarized configuration for DC filtering and decoupling.
• Low ESR & High Ripple Handling: ESR of 30 mΩ at 100 kHz and ripple current ratings of 1.5 A at 120 Hz and 3 A at 100 kHz support high-frequency and high-current applications.
• Reliability & Lifetime: Load life specified at 2000 hours when operated at 105 °C, with defined endurance and damp-heat performance criteria from the datasheet.
• Automotive Qualification: AEC-Q200 qualified and explicitly listed for automotive applications.
• Environmental Compliance: RoHS directive compliant (2011/65/EU,(EU)2015/863).
• Package & Mounting: Radial lead can, 5 mm lead spacing, compact dimensions L: 1.3 cm × D: 1.0 cm for through-hole mounting and flow solder compatibility per the radial lead type specification.
• Temperature Range: Specified operating range from -55 °C to +105 °C with proven impedance stability across temperature extremes as listed in the datasheet.

Typical Applications

• Automotive power electronics: Capacitor for power-supply smoothing, decoupling and ripple suppression in systems requiring AEC-Q200 qualification.
• DC–DC converters: Low ESR and high ripple-current capability make it suitable for output filtering in high-frequency converters.
• Control modules and sensor electronics: Compact radial package and thermal endurance support use in electronic control units and sensor interface circuits.

Unique Advantages

• Low ESR performance: 30 mΩ at 100 kHz reduces voltage ripple and improves efficiency in high-frequency power stages.
• High ripple-current capability: Rated for 3 A at 100 kHz and 1.5 A at 120 Hz to withstand demanding AC stress in power circuits.
• Automotive-grade qualification: AEC-Q200 compliance for designs requiring automotive-level component qualification.
• Thermal endurance: 2000-hour load life at 105 °C provides predictable long-term behavior in elevated-temperature applications.
• Compact radial form factor: 5 mm lead spacing and a 1.3 × 1.0 cm can enable space-efficient through-hole layouts with reliable solder connection.
• Regulatory compliance: RoHS conformity for environmental and materials compliance across supply chains.
