Dillenburg, Germany Isabellenhuette has extended its LMx product range to include the size 0805 (LMI). The low-ohmic LMx precision resistors can be used over a value range of 1 to 100 mOhm and can be both reflowed and soldered. Typical applications include drive control units, filter circuits and low-cost electronics in automotive technology. The product range is also available in the sizes 1206 (LMK), 2010 (LMP) and 2512 (LMS). Special features of the LMx range include a tolerance range of 1 to 5 %, high pulse energy (up to 0.5 J), extremely low thermic internal resistance from <25 K/W and a load capacity of 0.25 to 2 W. They are compact and flat-framed, with low-inductance characteristics. The effective and uncomplicated method of construction offers cost-effective production, as reflected in the price to the customer. All LMx resistors are manufactured using the patented Isa-Plan foil technology. The use of Manganin, a high-resistivity material, offers a number of advantages, for example, a negligible thermal electromotive force against copper (less than 1 µV/K) and excellent long-term stability (better than 0.5 % under full loading). In addition, Manganin ensures a resistance value virtually unaffected by temperature over a range from -40 to + 170 °C. Isabellenhuette Heusler GmbH KG , Dillenburg, Germany. www.isabellenhuette.de.
