PLF0J221MDL4

The PLF0J221MDL4 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can package designed for demanding thermal and electrical environments. It delivers low ESR and high ripple-current capability in a compact, polarized radial-lead form factor tailored for automotive and other high-reliability power applications.

Key value comes from its low equivalent series resistance, high ripple-handling at both low and high frequencies, and a rated load life of 2000 hours at 105°C. The part is AEC-Q200 qualified and RoHS compliant, and it is compatible with lead-free flow soldering conditions.

Key Features

• Electrical Performance — 220 µF capacitance at 6.3 V rated voltage with ±20% tolerance, delivering stable decoupling and bulk energy storage for low-voltage power rails.
• Low ESR — ESR of 20 mΩ measured at 100 kHz (20°C) for reduced power loss and improved transient response.
• High Ripple Current — Supports 1.6 A at 120 Hz and 3.2 A at 100 kHz, enabling robust performance in switching and high-frequency power circuits.
• Thermal and Life Ratings — Operating temperature range of −55°C to +105°C with a rated load life of 2000 hours at 105°C, suitable for elevated-temperature operation.
• Reliability & Qualification — AEC-Q200 qualified and conforms to RoHS directives (2011/65/EU, (EU)2015/863), supporting regulated and reliability-focused designs.
• Mechanical & Mounting — Radial lead can package with 2.5 mm lead spacing and compact dimensions (L: 1.05 × D: 0.63 cm), compatible with lead-free flow soldering processes.
• Polarity & Handling — Polarized aluminum polymer construction for straightforward integration into polarized DC circuits.

Typical Applications

• Automotive power filtering — Low ESR and high ripple capability make this capacitor suitable for power-rail decoupling and smoothing in automotive electronics.
• DC–DC converter output — Compact capacitance and high ripple current ratings support output stage filtering in switched-mode supplies.
• Sensor and control modules — Stable performance across −55°C to +105°C and AEC-Q200 qualification support use in temperature-varying, reliability-critical control circuits.

Unique Advantages

• Low power loss: 20 mΩ ESR at 100 kHz reduces I²R losses and improves efficiency in power delivery circuits.
• High-frequency capability: 3.2 A ripple at 100 kHz provides reliable filtering for high-speed switching applications.
• High-temperature endurance: 2000-hour load life at 105°C offers predictable aging characteristics for elevated-temperature assemblies.
• Automotive-grade qualification: AEC-Q200 qualification aligns the part with automotive reliability requirements.
• Assembly-friendly packaging: Radial-lead can with lead-free flow soldering compatibility simplifies through-hole assembly processes.
