The CSP series of PCB energy absorption resistors are manufactured from inorganic materials such as graphite and Al₂O₃, which are sintered at high temperatures to form a solid core. The resistive element uses a semiconductor mechanism, ensuring low inductance suitable for high-frequency applications. The surface is encapsulated with epoxy resin, providing excellent sealing and moisture resistance. These resistors can absorb random strong pulse energy release within a short time, making them ideal for applications such as power transmission, electric traction, pulse power sources, and induction heating.
