Capacitor achieved both high performance and high reliability

• Capacitor with the electrolyte fused with conductive polymer and electrolyte liquid
• As features of both conductive polymer and electrolyte liquid, large ripple current(low Equivalent Series Resistance : ESR), low leakage current and high reliability contribute to downsizing and high reliability of the equipment
• Suitable for automotive equipment and base stations which need compact and high reliability components.

Characteristic comparison with aluminum electrolytic capacitors, replacement examples

Capacitance frequency characteristics

Hybrid capacitor : 50V 10μF (ø5x6)
Aluminum electrolytic capacitor : 25V 100μF　(ø6.3x6)

In the high frequency band, a aluminum electrolytic capacitor with large capacitance can be replaced with the hybrid capacitor with small-sized and small-capacitance.

ESR(100kHz) temperature characteristics

Hybrid capacitor : 35V 47μF (ø6.3x6)
Aluminum electrolytic capacitor : 35V 330μF (ø10x10)

The hybrid capacitor has stable ESR characteristics from high temperature to low temperature, so it can be replaced with a small-sized hybrid capacitor.

Characteristic comparison with ceramic capacitors (MLCC), replacement examples

DC bias characteristics of capacitance

Hybrid capacitor：25V 22μF, (ø5x5.8)
MLCC : 25V 22μF, x5R, (3.2x1.6)

Hybrid capacitors have no change in capacitance due to DC bias
The capacitance of MLCCs is greatly reduced by DC bias.

Replacement of MLCCs with hybrid capacitors

	MLCC		Hybrid capacitor
Mounted circuit area imag
Series, part number	-		ZA Series EEHZA1E220R
specification	25 V, 22 µF, 3.2 x 1.6 mm		25 V, 22 µF, ø5 x 5.8 mm
Quantity	5 pcs		1 pc
Effective capacitance	22 µF 22 μF x 5 pcs x 20% = 22 μF (Capacitance reduced by 15 VDC)		22 μF (No Capacitance reduced by 15VDC)

Since the capacitance of MLCCs is reduced by applying voltage,
replacing MLCCs with hybrid capacitors can reduced quantities and space.
