Power modules serve as the core power-supply units for a broad range of electronic equipment, encompassing switch-mode power supplies (SMPS), DC-DC converter modules, industrial power supplies, server power supplies, adapter power supplies, and other similar categories. These modules are typically subject to challenging operating conditions, including high-frequency switching, load-step transients, inrush-current surges, and wide-temperature-range operation.

Non-inductive resistors are a special type of resistive device that, through specialized structural design, reduce their parasitic inductance (inductive reactance) to an extremely low, negligible level.

Alloy resistors are precision power resistors that utilize Manganin, Constantan, or Nichrome alloys as the resistive element. They are characterized by low TCR, high precision, high current handling capability, and low resistance values.

Engineered with a specialized anti-sulfuration design, this resistor delivers robust resistance to sulfur-induced failure, guaranteeing stable operation and extended service life in harsh industrial atmospheres.

This product is a cost-effective preferred solution for current sensing, voltage dividing, and current limiting applications in a wide range of equipment, including power adapters, battery chargers, lithium-ion battery protection circuits, home appliance control boards, and power tools.

With a compelling combination of low TCR, high accuracy, low inductance, high power capacity, surge tolerance, and exceptional load stability, the alloy resistor has become the essential building block for current sensing, power monitoring, and overcurrent protection in modern HVAC systems.

In demanding power applications—including industrial controls, power modules, and high-frequency systems—the performance of the power resistor is a critical factor that directly governs equipment safety, conversion efficiency, and long-term reliability.

Engineered for high-precision, low-TCR, and high-power applications, HoBH bare alloy resistor series overcomes traditional design constraints. Providing reliable and economical current sensing and voltage dividing performance across multiple sectors, it establishes a new industry benchmark for bare alloy resistor excellence.
