Trimmers

Trimmers allow for easy adjustment of resistance values through physical manipulation. Vishay offers single- and multi-turn trimmers in a variety of case styles, sizes, and technologies. Trimmers are variable resistors that are commonly used for all applications in which the exact ohmic value needed for the design is not defined in advance. They offer easy adjustment (generally done with a screwdriver) and stability after being assembled on the PCB.

Main parameters:

  • Single-turn or multi-turn (single-turn trimmers are cheaper, while multi-turn devices offer more precise turning)
  • Through-hole or SMD designd (depending on the customer's choice)
  • Adjustment range: defines the max ohmic value needed
  • Overall dimensions: dependent on the available space on the PCB

Sealing level: dependent on customer's constraints
