WBC series of wire bondable chip resistors feature self-passivating tantalum nitride thin film technology on silicon substrates.
 
According to Dr. Debasis Roy, director of IRC Advanced Film Division’s Thin Film Business Unit, the resistors have an unmatched resistance range. “We have extended the resistance values for these resistors to range from 10 to 400KW. The extended range allows for better surge protection in higher power applications, such as hybrid circuits.” 

 Absolute tolerance ranges are down to ±0.1%, with absolute TCRs to ±25ppm/°C.
 
The resistor film provides stability over time and temperature, for increased power dissipation.

The chip resistors are available in 0202 and 0303 chip sizes.  The 0303 center-tapped chips can be used in feedback circuits of amplifiers.

An alternative to liquid epoxy for high-volume epoxy sealing applications, Uni-form epoxy preforms are one-part epoxy resins that are solid at room temperature. When heated, they melt and cure, forming a consistent seal that protects components from dust, moisture, oil, flux, solvents, conformal coatings, and other contaminants.
 
Close tolerances on preform configurations, consistent pre-mixed ratios of resin to catalyst, and consistent viscosity from beginning to end of batch ensure uniform results. 
 
Can be dispensed as rapidly as 200 to 600 parts/min. with little or no operator training; extensive operator experience is not required for uniform results. Said to eliminate pot-life concerns and costly cleanup procedures. Available in a range of shapes, sizes and materials.

Servo-Flo 505 Fixed-Ratio Meter System is for automated, robotic or manual dispensing applications. This single-servomotor dispensing system allows fixed and variable dispense rates while providing on-ratio materials that meet suppliers’ specifications.
 
Three levels of operator interface controls are available; these quickly set output flow rates and adjust material volume settings. The automation or the operator can select different stored flow and volume programs.
 
Has positive rod displacement metering, dispenses precise bead profiles or precision volumetric shots. Flow rates are varied on-ratio during the dispense cycle to provide different shot flows, bead diameters and tip speeds.
 
Accepts low- to high-viscosity materials and is supplied by pumps or pressure tanks. Meter, control panel and supply can be floor-mounted, portable-cart mounted or enclosed in a cabinet.
