PCK0E561MCO1GS

The PCK0E561MCO1GS is a 560 µF, 2.5 V conductive polymer aluminum solid electrolytic capacitor in a compact SMD can package. Designed for demanding electronic power applications, it delivers ultra-low ESR and high ripple-current capability in a surface-mount form factor.

Ideal for automotive electronic modules and other high-reliability systems, this AEC-Q200 qualified part combines high capacitance, low impedance and a 2000-hour load life at 105°C to support robust power smoothing and decoupling in temperature- and vibration-prone environments.

Key Features

• Capacitance & Voltage — 560 µF rated at 2.5 V with ±20% tolerance for bulk decoupling and energy storage in low-voltage rails.
• Ultra-low ESR — 9 mΩ ESR specified at 100 kHz, minimizing voltage ripple and power loss in high-frequency circuits.
• High ripple-current capability — 2.25 A at 120 Hz and 4.5 A at 100 kHz, enabling effective handling of AC stress and switching currents.
• Thermal and lifetime performance — Rated for operation from −55°C to +105°C with a load life of 2000 hours at 105°C.
• Automotive-grade qualification — AEC-Q200 qualified for applications requiring automotive-level component screening.
• SMD can package — Radial can SMD (L: 7 × D: 8 mm) for compact surface-mount assembly; recommended land size 8.3 × 8.3 mm.
• Reflow and environmental compliance — Supports lead-free reflow soldering (peak up to 260°C per datasheet reflow conditions) and is RoHS compliant.
• Polarized, solid polymer construction — Conductive polymer chemistry offers stable performance with low loss and reliable leakage characteristics.

Typical Applications

• Automotive electronic modules — Provides bulk decoupling and smoothing in automotive power rails where low ESR and high ripple tolerance are required.
• Power supply filtering — Suited for post-regulator filtering and energy buffering on low-voltage, high-current boards.
• DC–DC converters — Supports switching converters that demand low impedance at high frequency and robust thermal endurance.

Unique Advantages

• Reduced voltage ripple: 9 mΩ ESR at 100 kHz helps lower output ripple and improve voltage stability in high-frequency circuits.
• High AC stress tolerance: Ripple current ratings of 2.25 A (120 Hz) and 4.5 A (100 kHz) allow the capacitor to withstand switching and ripple loads.
• Long-term thermal reliability: 2000-hour load life at 105°C demonstrates endurance for elevated-temperature operation.
• Automotive qualification: AEC-Q200 rating supports use in automotive-grade designs requiring screened components.
• Surface-mount convenience: Compact radial can SMD package with specified land pattern simplifies board layout while delivering high capacitance density.
• Lead-free assembly compatible: Reflow capability up to 260°C peak per datasheet enables lead-free manufacturing processes.
