RCD Series MW provide a cost-effective solution for demanding
applications. Advantages include superior surge capability, improved
temperature stability, moisture resistance, noise, and a significant
space and cost savings over molded models. MW3 & MW5 feature
compliant gullwing terminals, which act as standoffs to reduce
PCB temperature and help minimize TCE stress (utilize compliant
terminals in applications with wide temp. gradients).
