PLX1V390MCL1

The PLX1V390MCL1 is a radial-lead conductive polymer aluminum solid electrolytic capacitor designed for high-reliability applications. It delivers low ESR and high ripple-current capability in a compact radial can package, targeting automotive and other demanding electronic systems.

Key value propositions include stable operation across a wide temperature range (–55 °C to +125 °C), extended high-temperature lifetime, and qualification to AEC-Q200 standards for use in qualified automotive designs.

Key Features

• Capacitance and Voltage — 39 µF nominal capacitance with a 35 V rated working voltage; ±20% tolerance at 120 Hz, 20 °C.
• Low Impedance / Low ESR — ESR of 33 mΩ measured at 100 kHz, supporting low-impedance decoupling and stable performance at high frequency.
• High Ripple Current — Rated ripple current of 360 mA at 120 Hz and 720 mA at 100 kHz, enabling robust handling of AC stress in power circuits.
• Extended High-Temperature Life — Endurance rated to 3000 hours at 125 °C with defined post-test limits (capacitance within ±20%, ESR and tan δ ≤150% of initial values).
• Wide Operating Temperature — Specified from –55 °C to +125 °C with impedance stability across this range (Z(+125 °C)/Z(+20 °C) ≤ 1.25 at 100 kHz).
• Automotive Qualification — AEC-Q200 qualified, suitable for qualified automotive electronics applications.
• Radial Lead Package — Radial can with 3.5 mm lead spacing and compact footprint (L: 9 × D: 8 mm); compatible with lead-free flow soldering conditions.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive power modules — Bulk filtering and decoupling on 12 V and intermediate rails where low ESR and high ripple current are required.
• Engine control and powertrain electronics — High-temperature endurance and AEC-Q200 qualification support use in elevated-temperature control environments.
• On-board power supply decoupling — Compact radial package for localized energy buffering and transient suppression in constrained PCB layouts.

Unique Advantages

• Reliable high-temperature performance: 3000-hour lifetime at 125 °C provides predictable ageing behavior for long-duration thermal stress.
• Low-impedance operation: 33 mΩ ESR at 100 kHz combined with high ripple-current ratings enables effective high-frequency decoupling and reduced voltage drop under load.
• Automotive-grade qualification: AEC-Q200 rating supports use in certified automotive electronics projects.
• Compact radial form factor: Small L × D footprint and 3.5 mm lead spacing permit space-efficient placement on PCBs while remaining through-hole mounted.
• Manufacturing-friendly: Designed for lead-free flow soldering compatibility to fit modern assembly processes.
• Standards compliance: RoHS conformity simplifies environmental compliance for assemblies.
