CTX33-18971-R is a surface mount power inductor/transformer from the Econo-Pac/Octa-Pac series that can be used as single or coupled inductors or 1:1 transformers providing isolation between two windings. The device features a secure 4-terminal mounting configuration and is designed around high frequency, low loss material for optimal performance. It operates within an ambient temperature range of -40°C to +85°C and a storage temperature range of -40°C to +125°C, with an infrared reflow temperature rating of +240°C for 30 seconds maximum. This RoHS compliant component (-R option) is suitable for applications including DC-DC converters, buck, boost, forward, and resonant converters, noise filtering, filter chokes, and 1:1 300Vdc isolation transformers.
