Murata has released the UMAC, a miniature device with a high energy storage capacity. The device has been developed to meet growing demand for compactness, large capacity, extended cycle life (to eliminate the need for replacement), low internal resistance, fast charging and discharging, and the ability to withstand load fluctuations.
The UMAC, can be used as a secondary battery in the same way as a capacitor would traditionally be used, however the UMAC, energy device exhibits superior charge/discharge characteristics and has an extended service life compared with conventional batteries. Furthermore the device is able to maintain a flat voltage characteristic under a wide range of load characteristics.
The UMAC, device has a nominal voltage of 2.3V and a capacity of 3mAh, ESR is just 800 milliohms and operating temperature range is 0ºC to +70ºC. The device can be discharged at a maximum rate of 10C (30mA).
The BAC05 series from Murata offers a rugged design, efficient and flexible family of AC/DC converters suitable for a wide range of applications including industrial, medical, building automation and IoT devices.
Murata have introduced the NFG0QHB series of common mode noise filters, designed for high-speed differential interfaces such as those used on USB and HDMI interfaces.
Murata have extended their range of Lithium Coin cells to include High Drain and Extended Temperature types to meet the demanding requirements of next generation IoT devices.
Murata's range AMR sensors are magnetic switches that have an integrated IC that produces high and low output digital signals based on the magnetic field strength detected.
Murata manufacture a wide range of sounder and buzzer components based on Piezoelectric ceramic technology, the range includes surface mount and through hole housed sounders and Piezoelectric diaphragms.
The LXRW series from Murata are innovative variable capacitors which allow their capacitance value to be varied by applying a voltage, the capacitance varies proportional to the voltage applied making them ideal for use in frequency tuning circuits.
