PLF1A680MDL4

The PLF1A680MDL4 is a radial-lead, conductive polymer aluminum solid electrolytic capacitor designed for demanding power-decoupling and filtering tasks. It delivers low equivalent series resistance (ESR) and high ripple-current capability in a compact radial can package.

Targeted at automotive and industrial electronics, this capacitor combines a 68 µF capacitance at a 10 V rating with a robust operating temperature range and AEC-Q200 qualification for reliability in harsh environments.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a 10 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Conductive Polymer Construction — Solid electrolyte technology providing inherently low ESR and stable performance across temperature.
• Low ESR — ESR specified at 25 mOhm (100 kHz, 20°C), supporting efficient high-frequency decoupling and reduced power loss.
• High Ripple Current — Rated for 1.45 A at 120 Hz and 2.9 A at 100 kHz, enabling effective filtering in DC–DC converters and power rails.
• Thermal & Life Performance — Load life of 2000 hours at 105°C and operating temperature range of −55°C to +105°C for sustained high-temperature operation.
• Automotive-Grade Reliability — AEC-Q200 qualified and designed to meet endurance and damp-heat requirements listed in the PLF series datasheet.
• Radial Can Package — Compact radial can with 2.5 mm lead spacing and dimensions L: 1.05 × D: 0.63 cm for through-hole assembly; compatible with lead-free flow soldering conditions.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU) 2015/863).

Typical Applications

• Automotive power rails — Bulk filtering and decoupling on ECU and control-module power supplies where low ESR and high ripple capability are required.
• DC–DC converters — Output smoothing and high-frequency ripple suppression in compact converter designs.
• Sensor and actuator electronics — Local energy storage and transient suppression for reliable operation across −55°C to +105°C.

Unique Advantages

• Low-loss operation: 25 mOhm ESR at 100 kHz minimizes dissipation and improves power efficiency in high-frequency circuits.
• High ripple handling: Rated ripple currents (2.9 A at 100 kHz) let designers use smaller capacitance values while maintaining ripple control.
• Automotive-qualified: AEC-Q200 qualification supports use in vehicle electronics requiring standardized reliability testing.
• High-temperature endurance: 2000-hour load life at 105°C demonstrates sustained performance under elevated operating temperatures.
• Compact radial form factor: Small can dimensions and 2.5 mm lead spacing simplify placement in through-hole assemblies and compact boards.
• RoHS and lead-free solder compatible: Meets RoHS directives and corresponds to lead-free flow soldering conditions for modern manufacturing processes.
