This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.

MURATA DK1 X/Y Class SMD Ceramic Capacitors

Murata DK1 series are surface mount Y1 class safety capacitors that enable smaller and lower-profile AC-DC switching power supplies, such as those used in AV equipment, LED illumination, and 1U rack-mounted devices.

 The DK1 series measures just 11.4mm x 6.0mm x2.5mm and uses disc ceramic capacitor technology that enables high withstand voltage and certification to IEC60384-14 Y1 class requirements with ratings up to 300VAC. The capacitors can also be used as Class X1 capacitors at voltages up to 440VAC. 

Capacitors are available with values from 10pF to 1500pF with 10% to 20% tolerance. Murata DK1 series Y1 safety capacitors can operate at up to 125°C and provide 6000MΩ of insulation resistance.
