PFBR45-ST13150S is a power line communication (PLC) transformer from Bourns designed for functional insulation applications with a working voltage of 400 VDC. It features a primary inductance of 1 mH (±35% -30%) at 100 kHz / 1V, a turns ratio of 2:1 (±3%), and a leakage inductance of 1.5 µH typical with a 2 µH maximum. The transformer operates over a temperature range of -40°C to +125°C (including self-temperature rise) and is housed in a compact SMT package with excellent transmission characteristics. It is specifically designed for ST Micro 8500 PLC System-on-Chip (SoC) applications and complies with EN 62368 and EN 61885 standards. Common applications include smart grids, automatic meter reading systems, home automation, CCTV cameras, and street lighting systems.
