RX27-8 Ceramic Housed Wirewound Resistor

RX27-8 Ceramic-housed wirewound resistor


Product Introduction:


  • Product Features: Lead wires are silicone braided wires, customizable length, low inductance. Ceramic shell packaging, flame retardant, belongs to insulated resistors.
  • Application Areas: Generally used in DC or low-frequency AC circuits. Can be used as braking or charge-discharge resistors.
  • Product Standard: Detailed specifications of RX27 ceramic shell power wire-wound resistors under standard Q/RW370-1994.
  • Can negotiate to provide non-inductive products, designated by adding "N" before the model number.
  • Capable of producing products that comply with RoHS and REACH requirements.
