Cal-Chip Electronics, Incorporated RM SERIES Thick Film Chip Resistors - RM Series "Fixed Chip Resistors" manufactured for more compact electronic components and automatic mounting system. These Chip Resistors have electrical stability and mechanical stress due to used reliable metal glazed paste printed on Alumina substrate. Resistors will reduce your cost and save developmental time. FEATURES 1. Very small, thin and light weight. 2. Both flow soldering and reflow soldering are applicable. 3. Owing to the reduced lead inductance, the high frequency characteristic is excellent. 4. Suitable size and packaging for surface mount assembly. PART NUMBERING (EX) 0805 1 /10 watt 5% 10ohm RM 1 10 2 J 3 100 4 CT 5 1. Code Designation: Thick Film Chip Resistors 2.
