The PLF1E220MCL7 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can package. It delivers low ESR and high ripple-current performance in a compact φ8 × 7 mm footprint with 3.5 mm lead spacing.

Designed for demanding temperature and endurance requirements, this capacitor is rated for 25 V, 22 µF capacitance with ±20% tolerance and an operating temperature range of −55 °C to +105 °C, making it suitable for automotive electronics and other robust power applications.

Key Features

• Capacitance & Voltage: 22 µF rated at 25 V with ±20% tolerance (measured at 120 Hz, 20 °C).
• Low ESR Performance: ESR specified at 50 mΩ measured at 100 kHz, delivering reduced loss and improved transient response.
• High Ripple Current: Supports 900 mA at 120 Hz and 1.8 A at 100 kHz, enabling effective smoothing in high-frequency power circuits.
• Reliability & Lifetime: Load life of 2000 hours at 105 °C; endurance and damp-heat specifications maintain capacitance, tan δ and ESR within defined limits after testing.
• AEC-Q200 Qualified: Rated and tested for automotive-grade reliability; suitable for automotive electronic applications where AEC-Q200 qualification is required.
• Radial Lead Package: φ8 can size with radial leads and 3.5 mm lead spacing; compatible with lead-free flow soldering conditions.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Power Electronics: Bulk decoupling and ripple filtering in vehicle power supplies and DC–DC converters, leveraging high ripple-current capability and AEC-Q200 qualification.
• On-board Power Regulation: Local energy storage and smoothing for voltage regulators and power modules where low ESR improves transient response.
• Embedded & Control Systems: Decoupling and stabilization for microcontroller power rails and sensor interfaces operating over −55 °C to +105 °C.

Unique Advantages

• High ripple tolerance: Rated ripple currents up to 1.8 A at 100 kHz reduce heating under high-frequency load and extend system reliability.
• Low ESR for improved efficiency: 50 mΩ ESR at 100 kHz minimizes power loss and supports cleaner power delivery in compact designs.
• Automotive-grade qualification: AEC-Q200 rating provides documented reliability for automotive electronics design requirements.
• Extended high-temperature life: 2000 hours at 105 °C endurance supports sustained operation in elevated-temperature environments.
• Radial-lead, solder-ready package: Can-style package with lead-free flow soldering compatibility simplifies board-level assembly for through-hole designs.
