TFBR Stainless Steel Power Resistors The TFBR series provides high power density in a low profile package. Designed for easy assembly and supplied with a variety of terminal styles, the film technology lends itself to high frequency operation due to its low inductance characteristics. The added benefit of high instantaneous pulse capacity also makes the TFBR suitable for braking, snubbing and discharge requirements. This product is RoHS compliant.
