Aluminum Housed Resistors - Chassis AHR / AHRN

  • Aluminum Housed Resistor Applications – Snubbers Resistor for snubber circuits, Braking Resistors, Gate Resistors, Dumping Resistors for Motor Controls, Rush Current protections, Snubber Resistors for snubber circuits (Low Inductance type)
  • AHR : 5W - 1000W
  • Low Inductance AHRN & Precision Resistance Tolerance type are available

  • This series of resistors are made with Nickel Copper or Nickel Chromium resistance wire on ceramic core fitted into anodized Heat sink using high temperature moulding compound.

  • With strong leads which is good for pulse current handling
  • Good for as Snubber Resistors in snubber circuits
  • Good for high pulse / surge power and current dissipation applications. Please state your application conditions.
  • Suitable for industrial machines and equipment
  • Durable and can withstand stronger vibration, moisture and solvent
  • Improved heat conduction and convection design
  • For Low Ohmic Resistors, please tell working Voltage and Duty Cycle. Different Voltage can cause different current. And in turn different resistance wire is needed.

  • Support Low temperature coefficient
  • Support Low Inductance requirement - as medium frequency resistors and snubber resistors
  • Customizable connection and mounting
  • We support Aluminum Housed Resistor for wide variety of industrial applications. Different applications can have a very different resistor electrical and mechanical profile requirement.

  • Accept large, small quantity orders and PayPal.
  • Prompt Delivery, within 10 - 15days, e-mail us for pricing.
