Vishay WSHM2818 Power Metal Strip Resistors

Vishay’s WSHM2818 Power Metal Strip resistors feature an all-welded construction ideal for pulse applications, voltage division, and current sensing.

The design incorporates improved thermal management that enables high power density and reduces measurement error, while also offering very low inductance. The resistors can handle 7W in a 2818 case size, and Vishay’s proprietary processing enables resistance values down to 1mΩ and tolerance down to plus or minus 0.5%. 

Vishay WSHM2818 Power Metal Strip resistors are AEC-Q200 qualified and are unaffected by high sulfur environments. 

  • All welded construction ideal for pulse applications, voltage division, current sensing 
  • Improved thermal management enables high power density, reduces error 
  • Very low inductance: < 5nH 
  • High power density: 7W in 2818 case 
  • Resistance values: 0.001Ω to 0.2Ω, ±0.5% or ±1% tolerance 
  • AEC-Q200 qualified
