What made you select Knowle’s new StackiCap MLCC Capacitors? What value do these products offer?
Knowles new StackiCap MLCC Capacitors offer unmatched combination of case size, capacitance, and voltage and can significantly reduce PCB space for applications needing high voltage, high capacitance MLCCs. The unique design incorporates a patented sponge layer technology allowing the part to be stacked up while terminated as a single MLCC homogenous design. Typical MLCC material is brittle and subject to cracking due to the piezoelectric, which causes parts to vibrate when current is applied and possibly cracking the MLCC. The sponge layer helps dampen the vibration and reduce the potential for cracking.
StackiCap products are available in voltage ratings up to 2kV and capacitance options up to 5.6uF. Available case sizes include 1812, 2220, 2225, and 3640 with operation temperature range from -55C to +125C and most are available with AEC-Q200 qualification.
