Panasonic 470 μF Capacitor 25V dc, Surface Solder

Panasonic Capacitor, 470μF Capacitance, 25V Voltage - EEEFK1E471GP

This capacitor is a surface-mount polar aluminium electrolytic device designed for use in demanding electronic and automotive systems. It provides bulk energy storage and stabilisation for DC rails in high-temperature environments and is intended for automated assembly using tape packaging and solder termination methods.

Features and Benefits:

• 470μF capacitance delivers substantial charge storage and smoothing
  25V rated voltage supports moderate low-voltage DC applications
  105°C maximum operating temperature allows extended thermal margin
  850mA ripple current improves performance in high-frequency circuits
  5000h expected operational lifetime suits long-term service conditions
  20% tolerance accommodates typical capacitance variance for design margins

Applications

• Suitable for DC power-filtering in automotive control modules
  Ideal for voltage-stabilisation in industrial automation drives
  Used with power-supply modules in control and instrumentation units
  Can be used for decoupling in Compact SMD electronic assemblies

What mounting and soldering considerations apply?

The component is intended for surface-mount placement with solder termination, it is supplied on tape for pick-and-place machines to ensure consistent orientation and thermal contact during reflow.

How does the construction affect mechanical robustness?

The aluminium case provides a rigid enclosure that maintains polarity marking and withstands handling during automated assembly while offering effective electrolytic containment.

What environmental temperature range is supported in operation?

It operates correctly down to -55°C and up to 105°C, enabling use across cold-start conditions and elevated ambient temperatures without specification shifts.

How is leakage current relevant to circuit design?

The specified leakage current influences standby power and bias behaviour, so designers should account for this when calculating quiescent current and charge retention in low-current applications.

What standards and approvals are applicable for industry use?

The device meets automotive-grade AEC‑Q200 requirements and is RoHS compliant, supporting use in regulated manufacturing and automotive electronics.
