Wurth Electronics has released an innovative family of transformers, coupled inductors for the usage in energy harvesting applications. The WE-EHPI series was developed for the usage in application where power is generated by energy harvesting to power a device or charge a battery. Typically such applications can be found in fire, gas, alarm, and metering sensors and devices. Other points of usage are devices which are placed in the nature or cannot have a standard power source from the outlet or a battery. Würth Electronics Energy Harvesting Transformers are available in a compact package size of 6 x 6 mm with a max height of only 4 mm. Separated soldering pads allow an increased reliability of the circuit, and due to Würth Electronics advanced winding technology the tiny transformers also offer an increased performance in the circuit. The three available transformers in the turns ratio of 1:100, 1:50, and 1:20 fit with several integrated circuits for such applications.
