PLF0E821MCO8

The PLF0E821MCO8 is a radial-lead conductive polymer aluminum solid electrolytic capacitor designed for high-ripple, low-ESR power applications. Built for demanding thermal and electrical environments, this 820 µF, 2.5 V polarized capacitor delivers compact energy storage with robust lifetime performance.

Targeted at automotive and other industrial applications, the device combines low ESR and high ripple current capability with AEC-Q200 qualification and RoHS compliance to support reliable power-filtering and decoupling in space-constrained assemblies.

Key Features

• Capacitance & Voltage — 820 µF at a rated voltage of 2.5 V with ±20% tolerance, providing bulk capacitance for low-voltage power rails and energy buffering.
• Low ESR — Equivalent Series Resistance of 7 mΩ measured at 100 kHz (20°C), minimizing power loss and heat generation under high-frequency load.
• High Ripple Current — Rated ripple current of 5.6 A at 100 kHz (and 2.8 A at 120 Hz), suitable for high-duty switching and regulator output filtering.
• Thermal & Lifetime Performance — Operating range −55°C to +105°C with a specified load life of 2000 hours at 105°C.
• Package & Mounting — Radial, can-type construction with 2.5 mm lead spacing and compact dimensions (φ6.3 × 9 mm), compatible with lead-free flow soldering conditions.
• Quality & Compliance — AEC-Q200 qualified and RoHS compliant for regulated electronic assemblies.

Typical Applications

• Automotive electronic modules — Energy buffering and decoupling on low-voltage power rails in modules where AEC-Q200 qualification and high ripple performance are required.
• DC–DC converter outputs — Low ESR and high ripple current ratings make this part suitable for smoothing and stability on high-frequency converter outputs.
• Compact power assemblies — Small φ6.3 × 9 mm can size with radial leads provides bulk capacitance in space-constrained through-hole designs that require lead-free solder compatibility.

Unique Advantages

• Reduced thermal stress: Low ESR (7 mΩ at 100 kHz) lowers I²R losses, helping manage temperature rise in high-current applications.
• High ripple endurance: 5.6 A ripple current at 100 kHz supports demanding switching environments and reduces filtering component count.
• Long high-temperature life: Specified 2000 hours at 105°C provides predictable end-of-life characteristics for designs exposed to sustained elevated temperatures.
• Automotive-capable qualification: AEC-Q200 rating signals suitability for regulated automotive electronic assemblies requiring component-level qualification.
• Through-hole assembly compatibility: Radial lead form with lead-free flow soldering correspondence eases integration into conventional PCB assemblies.
