CADDOCK

Precision power resistors, current-sense resistors and current measurement solutions

 

About the manufacturer

Caddock Electronics is a US manufacturer specialising in high-precision and high-power resistors. The company focuses on components for applications where parameter stability, low parasitic inductance, accurate current measurement and efficient heat dissipation are critical.

Caddock’s portfolio includes power resistors in TO-126-, TO-220- and TO-247-style packages, current-sense resistors, precision film resistors and resistor networks. These products are designed for power electronics, measurement and control circuits where standard resistors may not provide sufficient durability or accuracy.

A key feature of many Caddock series is their non-inductive construction, reducing the resistor’s influence on switching and high-frequency circuits. This makes the brand relevant to both precision measurement paths and high-power applications.

 

Applications

Caddock resistors are primarily selected where measurement precision must be combined with high power handling or stable operation under demanding electrical conditions.

  • Power electronics – power resistors in converters, inverters and power supplies.
  • Current measurement – low-ohmic shunt and current-sense resistors.
  • Industrial automation – precision control and measurement paths.
  • Laboratory equipment – resistors with high stability and repeatability.
  • Electric drives – current measurement and limiting in power stages.
  • Switching and high-frequency systems – designs with reduced parasitic inductance.
  • High-power equipment – heat-sink-mounted resistor solutions.

 

CADDOCK products available from Maritex

Maritex offers specialised Caddock resistors for precision and high-power electronic circuits. The brand is particularly relevant to projects requiring low resistance values, stable parameters and efficient heat dissipation.

Available product groups include:

  • Power resistors.
  • Current-sense resistors.
  • Low-inductance resistors.
  • Precision film resistors.
  • Heat-sink-mountable resistor packages.

When selecting a Caddock resistor, resistance and tolerance should be considered together with power dissipation, cooling method, maximum current and pulse conditions. In current-sense applications, temperature coefficient and measurement-path layout are also particularly important.
