Ozonizer Removes Germs In Consumer And Automotive Apps

Murata’s ultra-compact MHM500 ozonizer module is constructed on a low-temperature co-fired ceramic (LTCC) element. Using a discharge electrode and a dielectric electrode within the LTCC board, the ozonizer creates a stable supply of ozone. Fabricating the electrodes within the LTC element extends the modules’ lifetimes. The ozone element measures 14.2 by 31.5 by 17 mm, and the power supply module is 36 by 50 by 24 mm. The module operates from a +12-V dc input voltage and consumes around 1 W. Ozone generation performance is 2.5 mg/h maximum. The MHM500 can be used to generate ozone in a broad range of consumer, industrial, and automotive accessory applications. Bacteria can proliferate in many appliances such as refrigerators and dishwashers, resulting in mildew, odors, and potential health risks. Previous ozone-creating units have been too large and expensive to incorporate into consumer appliances, but now, the compact MHM500 module makes this possible.
