Mini Thermopads® Triple Wrap Series

Our MTVA W3 Thermopads® are microwave absorbtive attenuators which offer a smaller physical size with increased frequency range. The series operates DC to 12.4 GHz. The MTVA W3 version of the Thermopad® offers metallization wraps around input, output, and ground terminals with small contact pads on the backside. The process permits inspectable solder fillets when flip chip mounting. Our application notes describes the mounting techniques to optimize RF performance, heat sinking, and mechanical support terminals for use with alternative high frequency attachment methods and space applications. This product is available with various plating options including RoHS compliant lead free silver over nickel plating, 60/40 low temperature solder plating or 60/40 solder fused finish for easy reflow processing.
