Panasonic 330 μF Capacitor 25V dc, Surface Solder 500

Panasonic Capacitor, 330μF Capacitance, 25V Voltage - EEEFP1E331AP

This is a polar aluminium electrolytic surface-mount capacitor designed for demanding electronic environments, including automotive applications. It provides energy storage and smoothing for DC circuits and operates across a wide temperature range suitable for intensive use. The device is supplied in carrier tape for automated assembly and features solder terminations for secure surface mounting.

Features and Benefits:

• 330μF capacitance reduces voltage ripple for stable supplies
  25V rating supports medium-voltage DC rail applications
  80mΩ low ESR improves transient response and efficiency
  850mA ripple current handles high AC components in DC lines
  2000h lifetime at elevated stress for predictable service life
  82.5μA leakage current minimises standby losses

Applications

• Suitable for automotive electronic control modules requiring AEC‑Q200 qualification
  Ideal for power-supply output filtering in industrial automation
  Used with motor-drive electronics to smooth switching transients
  Can be used for backup smoothing in battery-management systems
  Suitable for Compact consumer electronics needing surface-mount decoupling

What environmental extremes can it withstand during operation?

It is rated to operate from -55°C up to 105°C, covering typical automotive and industrial temperature profiles.

How does the construction affect soldering and assembly?

The aluminium case with solder terminations and carrier-tape packaging supports standard reflow processes and automated placement.

What tolerance should designers allow for capacitance variation?

The capacitance tolerance is ±20%, so circuit margins should accommodate this potential deviation.

How does polarity influence PCB layout?

Being a polar device, it requires correct orientation on the PCB and appropriate marking or silkscreen to prevent reverse installation.
