PLF0G821MDO1

The PLF0G821MDO1 is a radial-lead conductive polymer aluminum solid electrolytic capacitor designed for demanding power-filtering and decoupling tasks. It combines low ESR and high ripple-current capability with a compact radial can footprint for board-level power modules and control electronics.

Targeted for applications requiring wide temperature operation and automotive-grade reliability, this part delivers 820 µF at 4 V, a -55 °C to 105 °C operating range, and AEC‑Q200 qualification.

Key Features

• Capacitance & Voltage — 820 µF rated capacitance at 4 V for bulk decoupling and energy buffering on low-voltage rails.
• Low ESR — ESR = 6 mΩ at 100 kHz, minimizing voltage drop and heat generation under high-frequency ripple.
• High Ripple Current — 3.25 A at 120 Hz and 6.5 A at 100 kHz to support switching power supplies and converters.
• Temperature & Lifetime — Rated for -55 °C to 105 °C with a load life of 2000 hours at 105 °C for stable long-term performance.
• Package & Mounting — Radial lead, can-style package with 5 mm lead spacing and compact dimensions (L: 1.3 cm × D: 1.0 cm) for through-hole assemblies.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant, suitable for regulated industry deployments.
• Polarity & Tolerance — Polarized design with ±20% capacitance tolerance at 120 Hz, 20 °C.
• Soldering Compatibility — Supports lead-free flow soldering conditions appropriate for radial lead components.

Typical Applications

• Automotive power rails — Bulk decoupling and smoothing on 4 V power domains where wide temperature range and AEC‑Q200 qualification are required.
• DC–DC converters and power modules — Low ESR and high ripple-current handling reduce loss and improve stability in switching regulators.
• Embedded control electronics — Energy buffering and transient suppression for microcontroller and sensor supply circuits in harsh environments.

Unique Advantages

• Low-loss operation: 6 mΩ ESR at 100 kHz reduces dissipation under high-frequency switching and helps maintain lower junction temperatures.
• High ripple tolerance: Rated ripple currents of 3.25 A (120 Hz) and 6.5 A (100 kHz) support aggressive power-stage designs and high switching loads.
• Automotive-grade reliability: AEC‑Q200 qualification and a 2000-hour load life at 105 °C provide predictable endurance for vehicle and industrial electronics.
• Wide operating range: -55 °C to 105 °C rating enables use across extended-temperature systems without derating the capacitor’s core performance.
• Compact radial form factor: Small can dimensions and 5 mm lead spacing simplify layout in through-hole assemblies while preserving capacitance density.
• RoHS compliant: Lead-free materials and soldering condition support for lead-free flow processes.
