A1 Series The MODULOHM A-1 wirewound power resistors series come in two sizes. The 15W and 25W. Because all our resistors are fully welded they can be used in commercial as well as in industrial equipment. The resistor element is wound in a single layer on a glass fibre rod and the connection to the terminals are all welded with a unique welding technique. The resistor element is imbedded in a steatite case with a ceramic substance producing a resistor with high electrical qualities and excellent mechanical strength. The terminals are made of nickel silver and are hot-tinned to secure excellent solderability. The MODULOHM resistors are produced in EU offering customers a high grade of flexibility. Customer specified versions are possible. › Show more information › A-1 Series Datasheet › Contact sales department Specifications Power Range 15W- 20W Over Load 10*PN in 5 sec De-rating 100% @ 45°C - 65% @105°C Resistance Tolerance ± 10%, ± 5%
