A transducer array for applying an alternating electric field (e.g., a tumor treatment field, also referred to as TTField) to a body of a subject generally includes a plurality of capacitively coupled electrode elements. Typically, certain electrode elements on a given array tend to operate more hotter than other electrode elements. For example, in many anatomical contexts, the corner elements of the transducer array are often hotter than non-corner elements. By connecting capacitors in series with those electrode elements (e.g., corner elements) that often operate more hotter, the difference in operating temperature between the electrode elements that often operate more hotter and other electrode elements can be reduced. 用于向受试者的身体施加交变电场(例如，肿瘤治疗场，也称为TTField)的换能器阵列通常包括多个电容耦合电极元件。通常，给定阵列上的某些电极元件往往比其他电极元件运行得更热。例如，在许多解剖上下文中，换能器阵列的角元件往往比非角元件运行得更热。通过将电容器与往往运行得更热的那些电极元件(例如，角元件)串联连线，可以减小往往运行得更热的电极元件和其他电极元件之间的操作温度的差距。
