GJ4 Multilayer Ceramic Capacitors Murata Electronics GJ4 Multilayer Ceramic Capacitors offer a 0.10µF to 1µF capacitance range, 25VDC to 100VDC rated voltage, and maximum 3.2mm x 1.6mm dimensions. These capacitors feature dielectric material that enables a reduction of noise, making these product more effective for noise reduction than the general purpose models. Murata Electronics GJ4 Multilayer Ceramic Capacitors are ideal for audio circuits, such as digital amplifiers where there are distortion characteristics.
