Overview of PLX1D121MCL1 – Radial Lead Conductive Polymer Aluminum Capacitor, 120 µF / 20 V

The PLX1D121MCL1 is a radial-lead conductive polymer aluminum solid electrolytic capacitor from Nichicon's PLX series. It delivers low equivalent series resistance (ESR) and high ripple-current capability in a compact radial can package for demanding electronic environments.

Designed for automotive electronics and other high-reliability markets, this 120 µF, 20 V polarized capacitor offers a wide operating temperature range and a long-life rating for sustained performance in elevated temperatures.

Key Features

  • Capacitance & Voltage — 120 µF rated capacitance at 20 V with ±20% tolerance, suitable for power filtering and decoupling in low-voltage systems.
  • Conductive Polymer Electrolyte — Solid conductive polymer construction enables low ESR and stable performance across temperature and frequency.
  • Low ESR — 27 mΩ equivalent series resistance measured at 100 kHz, supporting efficient energy transfer and reduced heat generation.
  • High Ripple Current — Rated for 800 mA at 100 kHz and 400 mA at 120 Hz, allowing reliable handling of dynamic load currents.
  • Long Life at Elevated Temperature — Endurance rating of 3000 hours at 125°C with specified limits on capacitance change, tan δ, and ESR.
  • Temperature Range & Stability — Operates from –55°C to +125°C; impedance characteristics specified to remain within defined ratios vs. +20°C at 100 kHz.
  • Automotive-Grade Qualification — AEC-Q200 qualified for use in automotive electronic applications.
  • Radial Lead Package — Radial can package with 3.5 mm lead spacing and lead-free flow soldering compatibility; RoHS compliant.

Typical Applications

  • Automotive Electronics — Filtering and decoupling on vehicle power rails where AEC-Q200 qualification and high-temperature endurance are required.
  • Power Supply Filtering — Bulk and decoupling capacitor for DC–DC converters and voltage regulators needing low ESR and high ripple current handling.
  • Industrial Control Electronics — Energy smoothing and transient handling in control modules operating across a wide temperature range.

Unique Advantages

  • Low ESR (27 mΩ at 100 kHz): Enables lower voltage drop and improved thermal performance under high-frequency operation.
  • High Ripple-Current Capability: 800 mA at 100 kHz and 400 mA at 120 Hz support dynamic loads and reduce stress on upstream components.
  • High-Temperature Endurance: 3000 hours at 125°C provides predictable lifetime performance in elevated-temperature environments.
  • Wide Operating Temperature: –55°C to +125°C operation supports both cold-start and high-temperature duty cycles.
  • AEC-Q200 Qualified: Meets automotive qualification requirements for customers specifying automotive-grade components.
  • Radial, Lead-Free Solder Compatible: Through-hole radial can package with lead-free flow soldering compatibility simplifies board-level assembly for legacy and robust designs.
