Product Overview
C Series : Soft Termination Capacitor

The C Series Soft Termination MLCCs are used for crack mitigation purposes in applications exhibiting high mechanical and thermal stress.

View Product List

TDK Soft Termination Series is designed for use in applications where significant board flex may occur - especially in safety or high reliability designs. Conventional termination materials used in standard MLCCs are inflexible; therefore vibration, shock, or thermal expansion and contraction have the potential to crack or shear the solder joint between the component and the circuit board. In higher reliable applications, which are exposed to shock and vibration and to extreme temperature swings, this can result in higher failure rates in the field for conventional capacitors. TDK's soft termination provides very high resistance to mechanical and thermal stress to ensure the component can meet the requirements of its customers.
