PLF0E681MDO1

The PLF0E681MDO1 is a radial lead, conductive-polymer aluminum solid electrolytic capacitor in Nichicon's PLF series. It delivers low ESR and high ripple-current capability in a compact radial can package suitable for environments from -55°C to 105°C.

Key value propositions include a 680 µF capacitance at 2.5 V rating, very low ESR (6 mΩ at 100 kHz), and a rated load life of 2000 hours at 105°C. AEC-Q200 qualification and RoHS compliance make this part appropriate for demanding electronics assemblies used in automotive applications. Products in this series are scheduled to be discontinued and are not recommended for new designs.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 2.5 V and a tolerance of ±20% at 120 Hz, 20°C.
• Low ESR — Equivalent series resistance of 6 mΩ measured at 100 kHz, enabling lower losses in high-frequency circuits.
• High Ripple Current — Rated ripple current of 5.7 A at 100 kHz and 2.85 A at 120 Hz for robust AC stress handling.
• Thermal and Lifetime Performance — Operating temperature range -55°C to +105°C with a specified load life of 2000 hours at 105°C.
• Package & Mounting — Radial lead (can) package with lead spacing 3.5 mm and dimensions L: 1.2 × D: 0.8 cm; polarized device for through-hole mounting.
• Reliability & Compliance — AEC-Q200 qualification and RoHS directive compliance (2011/65/EU, (EU)2015/863); lead-free flow soldering condition correspondence is supported.

Typical Applications

• Automotive power electronics — Suited for modules that require low ESR and high ripple-current handling within the automotive temperature range.
• On-board power supplies — Bulk energy storage and smoothing where long life at elevated temperature (2000 h at 105°C) is required.
• High-frequency power circuits — Low ESR and measured performance at 100 kHz make this capacitor appropriate for circuits operating at high switching frequencies.

Unique Advantages

• Low-loss operation: 6 mΩ ESR at 100 kHz minimizes dissipation and improves efficiency in high-frequency designs.
• High ripple tolerance: Rated for 5.7 A at 100 kHz (and 2.85 A at 120 Hz), supporting demanding AC stress conditions.
• Wide temperature range with proven lifetime: -55°C to +105°C operation and 2000-hour endurance at 105°C support reliability in thermally challenging environments.
• Automotive-grade qualification: AEC-Q200 qualification confirms suitability for automotive electronics where that standard is required.
• Lead-free solder compatibility: Radial lead type designed to meet lead-free flow soldering conditions for modern assembly processes.

Why Choose PLF0E681MDO1?

PLF0E681MDO1 combines conductive-polymer aluminum chemistry with a radial through-hole package to deliver a compact, low-ESR capacitor capable of handling high ripple currents and extended high-temperature operation. Its AEC-Q200 qualification and RoHS compliance make it a choice for established automotive and industrial designs that require verifiable performance across a wide temperature range.

Because the part is specified for a 2000-hour life at 105°C and includes measured ESR and ripple-current ratings, it provides predictable behavior for engineers validating power rail stability and thermal endurance in existing designs. Note that this product is scheduled for discontinuation and is not recommended for new designs.
