Panasonic 330 μF Polymer Capacitor 35V dc, Surface - EEHZK1V331P

This polymer capacitor is a surface-mount hybrid electrolytic device designed for demanding electronic systems in automotive and industrial settings. It provides energy storage and smoothing for power rails in high-temperature environments, offering a Compact footprint suitable for densely populated boards. The component meets automotive quality screening standards and is intended for applications where long operational life and controlled leakage are important.

• Rated at 35V for higher voltage headroom and system margin
• Capacitance of 330μF ensures effective bulk energy smoothing
• Hybrid electrolyte construction reduces equivalent series resistance
• Ripple capability of 2800mA supports high-frequency power regulation
• Lifetime of 4000h at specified conditions enables extended service intervals
• Operating range from -55°C to 125°C sustains thermal resilience

• Suitable for power-supply decoupling in automotive ECUs
• Ideal for DC to DC converter output filtering in control units
• Used with motor-drive electronics requiring high ripple capacity
• Can be used for infotainment power-conditioning modules
• Suitable for industrial automation power-distribution boards

It is supplied in a taped surface-mount package and requires soldering to SMD pads sized for a 10mm diameter body with appropriate thermal profiles.

The device is polarised and must be oriented correctly with respect to circuit polarity to prevent malfunction or damage.

The capacitance tolerance is ±20%, so designers should accommodate potential variation in decoupling calculations.

The leakage is 115.5μA at rated voltage, which should be considered when calculating standby currents and bias networks.
