Description

RX27-7A Ceramic-housed wirewound resistor

Product Introduction:

  • Product Features: Leads can be directly installed with screws. Ceramic shell packaging, flame retardant, belongs to insulated resistor.
  • Application Areas: Generally used in DC or low-frequency AC circuits. Can also be used in three-phase circuits as a voltage equalizing resistor.
  • Product Standard: Q/RW370-1994 RX27 ceramic shell power wire-wound resistor detailed specification.
  • Can negotiate to provide no inductance products, designated by adding "N" before the model number.
  • Can produce products that comply with RoHS and REACH requirements.
