Würth Elektronik WE-FB Flyback Transformers are 1.8 mH .25A 12V transformers that have an operating temperature range of -40°C to +125°C, including temp rise. They are designed to comply with the following requirements as defined by IEC60950-1, EN60950-1, UL60950-1/CSA60950-1 and AS/NZS60950.l. They also feature a reinforced insulation for a primary circuit at a working voltage of 400VDC.
Würth Elektronik Midcom WE-UNIT Off-Line Transformer series is for use in AC/DC switch mode power supplies. The WE-UNIT Off-Line Transformer, Würth Elektronik Midcom's most standard offline transformer series, is designed to work with a wide input voltage range from 125-375Vdc with an isolation voltage of 4kV. The UNIT series uses the standard bobbins and core sizes EE13 and EE16, which guarantees short lead times. Both the EE13 and EE16 sizes are offered in a vertical and horizontal layout. The EE13 versions are constructed for 3W of power and have standard output voltages of 5V, 12V, and 24V. The WE-UNIT's EE16 options have up to 9W output power with output voltages of 5V, 12V, and 24V.
