HiTech / HTR Resistors

HiTech Resistors

Since inception in 1988, Hi Tech Resistors Pvt Ltd, popularly known as HTR in the electronics industry worldwide, has grown to become one of the leading resistor manufacturers in the world with presence in 35 countries through a network of representatives and distributors, worldwide.

HiTech Resistors produces over a hundred thousand wire wound and low ohm current sense resistors everyday in a wide variety of mounting and housing configurations.

Amongst the very few ISO/TS 16949:2009 certified resistive device manufacturers in the world, Hi-Tech Resistors has a strong presence in the automotive sector through its range of HVAC and ECS (Electronic Control Systems) resistive devices.

HiTech Resistors is one for the first companies to use the automotive ‘Product Part Approval Process’ methodology for industrial applications in which quality is always ‘built in at source’.

  • Incorporated in 1986 as a specialist producer of fixed wire wound resistors, HiTech Resistors has now transformed itself into a broad based manufacturer of Wire Wound, Low Ohm Current Sense Resistors, and Fusible Resistors with through hole and SMD terminations.
  • HTR is registered ISO 9001:2000 company certified by DNV (Netherlands)
  • HiTech Resistors Offers :
  • Wire Wound Resistors
  • Current Sense Resistors / Low Ohm Resistors
  • Surface Mount Resistors
  • Fusible Resistors

HTR now has the ability to offer techno-economic customized resistors for a wide range of applications.
