UBR Series
Ultra-Broadband Resistors
GENERAL DESCRIPTION
Passive Micro Component group is pleased to introduce the UBR Series of next generation of surface mount Ultra-BroadbandResistors. This product was designed utilizing our proprietary Glass Sandwich Flexiterm® Technology, (GSFT). The Flexiterm® is asurface mountable automotive qualified termination that adds an extra margin against damage due to flexture during installation.
The UBR Series has been designed with high quality selected materials that yield excellent performance. This product is ideal
for use in Optical Transceiver Modules or any application requiring excellent ultra-broadband performance. The use of glass
sandwich technology and precision laser triming reduces parasitic noise up to 40 GHz.

Dimensions are in inches.

NOTES:
Mounting will allow the solder fillet to travel up approximately 0.015" of the chip's end and side termination surface. Heavier fillets require a predeposition ofsolder paste and or an increase in pad dimensions. Typical solder paste application is a .008" to 0.01" thickness with >50% of volume in solder alloy. Can bemounted in both vertical and horizontal orientation without changing electrical performance
