  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

Applications

• 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

What mounting considerations apply to this component?

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.

How does polarity affect circuit placement?

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

What tolerance should designers allow when specifying capacitance?

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

How significant is the leakage current for low-power designs?

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