The Vishay RCL series is a long side termination thick-film chip resistor series available in sizes 0406, 0612, 1020, 1218, and 1225. Compared to standard thick-film chip resistors, RCL series parts have higher power dissipation capabilities; 2 to 4 times the power dissipation of standard thick-film chip resistors with similar chip size. The 1225 case size is rated for 2 W. For reasons that will be discussed later, RCL series parts are an excellent choice for applications with extreme thermal cycling requirements. RCL series parts are available with tolerance ±5% or ±1%. Many industries, including automotive, demand AEC-Q200 qualified resistors and Vishay’s RCL series meets this standard. The series is offered with a resistance range from 1 Ω to 2.2 MΩ. Additionally, jumper versions of RCL series parts are available with maximum current capability up to 12 A for the 1225 case size. For operation in harsh environments, the sulfur-resistant version known as the RCA-LS e3 series is available.
