XFMR High-Performance Isolation Transformers

RECOM Power XFMR High-Performance Isolation Transformers feature a subminiature design with UL-listed materials and SMD surface-mount or THD plug-in installation. These transformers withstand typical reflow oven peak temperatures and offer single, dual, or triple primary and secondary windings. The XFMR portfolio includes several variants. The RBE bobbin-type transformers cover the most common input/output voltage combinations. The RPE-021 and RBA-026 are also bobbin types and are designed for wide input voltage range power supplies. The RMR-028 and RMR-031 transformers are ideal for regulated 5V-to-5V or IGBT gate drive power supplies, while the remaining RMR transformers cover the most common input/output voltage combinations. Applications for RECOM XFMR transformers include infrastructure, data and telecom, test and measurement, power generation, energy distribution, and automation.
