Murata Manufacturing announced the ultra compact MHM500 ozonizer module 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, and because the electrodes are fabricated within the LTCC element it offers a long life characteristic.
Comprising both the LTCC element and a power supply module, 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 dish washers resulting in mildew, odors and creating potential health risks. Previously, ozone-creating units have been too large and expensive to incorporate into consumer appliances, but now, the compact MHM500 module makes this possible.
The ozone element measures 14.2 × 31.5 × 17mm, and the power supply module 36 × 50 × 24mm. The module operates from a + 12 VDC input voltage and has a low power consumption of approx 1 W. Ozone generation performance is 2.5mg/h maximum. A remote signal input controls the operation of the unit without the need to turn ON/OFF the input supply. The high voltage output of the power supply module incorporates an over-current and output protection circuit that can isolate the element supply in case of a fault condition.
Other potential applications include use in automotive interiors, nursing care equipment and pet accessories.
