RoHS POWER RESISTORS u (M)SQ(H, M, P T, U, Z) Series: Cement Box ,
INTRODUCTION
Cement-Box type resistors offer a choice of resistive elements inside a white flameproof cement box. In addition to being flameproof, these resistors are also non-corrosive and humidity proof. The available resistive elements are: SQ MSQ NSQ GSQ - Standard wire wound (all welded construction) - Metal oxide core (low inductance, high resistance) - Non-Inductively wound (Ayrton-Perry Method, all welded construction) - Fiber Glass Core
