Surface mount chip resistors are available in three different terminal styles for either RF or DC applications, such as bias voltage dropping or heaters. Terminal Style A has a full backside metalization for direct attachment to a heat sink or an item to be heated. Terminal Style B has wrap-around divider for low power SMT applications. Terminal Style C has a split ground that allows it be mounted as a resistor or termination. This style provides a larger ground area for increased heat dissipation and is an excellent choice for high power SMT applications.
