Panasonic 470 μF Polymer Capacitor 25V dc, Through Hole - EEHZS1E471V

This polymer capacitor is a hybrid electrolytic component designed for surface-mount use in demanding electronic and automotive contexts. It provides bulk capacitance for power smoothing, decoupling and transient suppression in circuits exposed to wide temperature ranges and elevated ripple conditions, while meeting automotive-grade reliability expectations.

• 470μF capacitance delivers substantial energy storage for power rails
• 25V rating supports low-voltage power supply applications
• High ripple capability 3.5A reduces voltage fluctuation under load
• Operating range -55°C to +135°C tolerates extreme thermal environments
• Hybrid electrolyte design offers low ESR for improved efficiency
• Polarised SMD construction enables Compact board-level placement

• Suitable for automotive power modules requiring AEC‑Q200 qualification
• Ideal for DC to DC converters and point-of-load filtering in automation systems
• Used with motor control electronics to handle high transient currents
• Can be used for backup smoothing in battery management systems

The component is rated for a 4000h operational lifetime at the specified conditions, indicating suitability for long-term use in high-temperature applications.

Plan for a leakage current of approximately 117.5 μA when calculating quiescent draw and standby power budgets.

The capacitance tolerance is ±20%, so designs must accommodate potential variation in effective capacitance values.

It is a polarised surface-mount device supplied in taped packaging, ensure correct polarity orientation and pick-and-place compatibility.
