In addition to being flameproof, these resistors are also non-corrosive and humidity proof. The available resistive elements are: SQ - Standard wire wound (all welded construction) MSQ - Metal oxide core (low inductance, high resistance) NSQ - Non-Inductively wound (Ayrton-Perry Method, all welded construction) DIMENSION & RESISTANCE RANGE(mm) RoHS Operating temperature range
- Wire wound : -55°C ~ + 155°C
- Metal oxide : -30°C ~ + 155°C Ohms 0.22 2.0 22 220 2.2K 22K Code 0R22 2R0 22R 220R 2K2 22K NOTE: All Specifications subject to change without notice.
