PLX1C391MDL1

The PLX1C391MDL1 is a Nichicon PLX series conductive polymer aluminum solid electrolytic capacitor in a radial lead can package. Designed for demanding environments, it offers low equivalent series resistance and high ripple-current capability in a compact radial form factor.

Targeted at automotive and other high-reliability systems, this capacitor delivers a combination of high-temperature endurance and electrical performance useful for power supply smoothing, decoupling and high-frequency filtering applications.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance (at 120 Hz, 20°C), suitable for bulk energy storage and decoupling in low-voltage power rails.
• Low ESR — 23 mΩ specified ESR at 100 kHz, enabling reduced loss and improved performance in high-frequency circuits.
• High Ripple Current — Rated ripple current of 565 mA at 120 Hz and 1.13 A at 100 kHz, supporting continuous AC stress and switching-power applications.
• Long High-Temperature Life — Endurance rated at 3000 hours at 125°C with defined limits for capacitance, tan δ and ESR after test; designed for sustained elevated-temperature operation.
• Broad Operating Temperature — Specified for −55°C to +125°C, suitable for systems exposed to wide thermal ranges.
• Radial Lead Package — Compact radial can with 5 mm lead spacing and dimensions L: 1.3 × D: 1.0 cm for through-hole mounting and robust mechanical connection.
• Manufacturing & Environmental — Compatible with lead-free flow soldering conditions and RoHS compliant; AEC‑Q200 qualified for automotive-grade reliability.

Typical Applications

• Automotive Power Electronics — Bulk smoothing and decoupling in automotive DC–DC converters and power rails where high ripple handling and temperature endurance are required.
• Embedded Power Supplies — Energy storage and filtering for board-level power regulation that benefits from low ESR and high-frequency performance.
• High-Temperature Electronics — Circuits operating in elevated ambient temperatures that require capacitors with defined endurance at 125°C.

Unique Advantages

• High-temperature endurance: 3000 hours at 125°C provides predictable long-term performance under sustained thermal stress.
• Low impedance at frequency: 23 mΩ ESR at 100 kHz and favorable impedance ratios across −55°C to +125°C help maintain stability in switching and high-frequency applications.
• Robust ripple handling: Specified ripple currents at both low and high frequencies minimize heating and extend component life in AC-stressed applications.
• Automotive-grade qualification: AEC‑Q200 rating supports use in automotive system designs that require supplier-backed reliability standards.
• Compact radial form factor: Through-hole radial can with 5 mm lead spacing simplifies PCB layout for power and filtering stages while providing strong mechanical anchoring.
• Manufacturing-ready: Lead-free flow soldering compatibility and RoHS compliance ease integration into modern production processes.
