Embedded Resistors – KOA Flat Chip Resistors for Embedded Substrates
Embedded resistors in a PCB allow the miniaturization of the total packages with improved electrical performance and highest reliability.
The key factors are high density mounting, good high frequency performance, excellent heat dissipation and high reliability by protection.
High Density Mounting
Embedded resistors are placed between the PCB layers
Heat Dissipation
PCB has better thermal conductivity than air
Reliability
Hot spot temperature is reduced
Epoxy resin is protecting embedded components
NEW: XR73- Series
KOA Flat Chip Resistors for Embedded Substrates
KOA’s resistors of XR73 series are especially designed for the usage in embedded technologies.
These extremely low profile parts of 0.13/0.14 mm height with Cu-terminations allow an easy placement between the PCB layers and can be connected with the top and bottom terminations to the PCB layers. This can realize high miniaturization of the circuit.
The parts are connected by conductive adhesion.
