Low-inductance low-profile high-power resistors suit high-frequency applications

Arcol Resistors has announced availability of an extended range of low-profile stainless steel power resistors. The TFBR series is manufactured using cutting-edge film technology, offering low inductance characteristics, making the power resistors particularly suitable to high-frequency applications. Also, the TFBR range now has the option of standard 6.3mm Faston terminals, in addition to solder-pad and push-on terminals. The TFBR series incorporates innovative packaging design, providing a high power density in a very low-profile package. The substrate thickness is 1mm ± 0.2mm and the wattages (on a heat sink) are 100W for the TFBR100; 300W for the TFBR300; and 900W for the TFBR900. The resistors are RoHS compliant and are designed for easy assembly. High Instantaneous Pulse Capacity (IPC) characteristics make the TFBR resistors suitable for braking, snubbing and discharge applications. The Pulse Power is 8 x PNom < 1s. Other characteristics include a tolerance of ±10% standard and the operating temperature is -55C to +200C. The Peak Voltage is 4kV and the Insulation Resistance is 1000Mohm. The maximum operating voltage is 1,000V and the temperature coefficient is ±150ppm/C.
