Resistor > Aluminium Housed Resistor AHR

Aluminium Housed Resistor AHR

Heavy-duty with improved heat convection design resistors – maximise Pulse Power Dissipation in a compact size.
With strong leads at both ends – good for pulse current handing.
Support mounting and connection customisation.

Aluminium Housed Resistor Applications – Braking Resistor, Gate Resistor, Dumping Resistor for Motor Control, Rush Current protection, Snubber Resistor for snubber circuits
AHR : 5W – 1000W
AHRN : Low Inductance type

This series of resistors use high quality Nickel Copper or Nickel Chromium 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 Resistor in snubber circuits
Good for High Pulse Power dissipation applications
Suitable for industrial machinery and equipment
Durable and can withstand stronger vibration, moisture and solvent
For Low Ohmic values, please tell the resistance, working Voltage and Loading Time or number of pulses per sec/min. Different Voltages can cause different loading currents.
Low temperature coefficient and better heat conduction
Customizable connection and mounting

We support Aluminium Housed Resistor for wide variety of industrial applications. Different applications can have a very different resistor electrical and mechanical profile requirement.
