WebAnswer to FAQ on flex crack countermeasures for TDK's Multilayer Ceramic Chip Capacitors (MLCCs). A flex crack is most frequently detected by electrical measurement as a decrease in insulation resistance. The MLCC's IR (Insulation Resistance) will decrease because the crack creates a weak point in the dielectric. WebAccordingly, the crack detection chip according to the present embodiment simply determines the presence of a crack with four tPD units 600 and operates the TDR module 300 only when it is determined that there is a crack, so the efficiency of crack detection is increased. can increase dramatically. In addition, since the approximate location of ...
