Capacitors aimed at power supply primary circuits
Murata Electronics
GB series of monolithic ceramic capacitors
Murata has increased the capacitance and reduced the cost of its GB series of monolithic ceramic capacitors for power supply primary circuits.
The monolithic capacitors are aimed at power supply primary circuit applications to achieve 56nF capacitance.
The cost was also reduced by 15 per cent over previous models by replacing the precious metals like silver that were used for the electrodes with a base metal such as nickel.
The GB series of X2-class safety capacitors has acquired certification to international capacitor safety standard IEC60384-14 and can resist electrical surges of up to 2500V.
The series offers a volume reduction of up to 90 per cent when replacing the typical choice of film capacitors for EMI reduction in power supply primary circuits, and use a third of the footprint.
The volume reduction makes the product ideal for small and low-profile equipment such as adaptors for laptop and notebook computers.
The GB series comes in 10, 15, 22, 33, 47 and 56nF versions measuring 5.7 x 5.0mm, with a low profile between 1.0 and 2.9mm, depending on capacitance.
