POWER RESISTORS Bourns Releases New Power Resistors Riverside, California - October 3, 2006 - Bourns is pleased to announce the release of several new power resistor models. The PWR4412-2S is a bare metal element through-hole shunt resistor exhibiting three different power ratings of 1, 2 and 3 watts respectively with excellent resistance and TCR characteristics. The target applications are current sensing in motor drives, power supplies, electro valves, and electricity meters. The CHF2525CNT is a 50 ohm 40 watt resistor chip, which has a maximum VSWR of 1.2 to 9 GHz of operating frequency. The resistor is used as a dummy load on products such as isolators, hybrid couplers and dividers in specialist RF applications requiring very high frequencies such as military and satellite communications. The CHF9838CNF is a 50 ohm 250 watt resistor mounted on a flange, which displays a maximum VSWR of 1.1 GHz to 2.2 GHz. This resistor is made with Aluminium Nitride material and is suitable for telecom and broadcast equipment. The CHF3020CBF is a 10 watt resistor mounted on a flange and designed to be used as a dummy load in a coupler or as a balance resistor between phases in a Wilkinson divider primarily for broadcast and military RF transmission equipment. Design kits are available on request. For product datasheets please check the Bourns website at www.bourns.com.
