Discover a broad range of resistors from Caddock – from power resistors and precision components to advanced resistor networks. Whether you work with power, measurement, or high-voltage applications, you will find solutions that combine high performance, stability, and compact design for demanding environments.
Power resistors in TO packages provide high power density in a small footprint, with easy mounting to a heat sink. With a non‑inductive design, power levels up to 100 W, and variants ranging from TO‑126 to TO‑247 and D‑Pak, you can optimize cooling, layout, and cost in everything from driver stages to braking and test applications.
Axial and radial power resistors combine high power capacity with a compact format and non‑inductive construction. With resistance ranges from low‑ohmic power resistors to precision levels of several MΩ, voltages up to approx. 6 kV, and temperature tolerance up to +275 °C, you get a flexible building block for power supplies, measurement, and high‑voltage circuits.
For precise current measurement, we offer resistors with very low resistance – from a few milliohms up to around 1 Ω – in everything from TO and D‑Pak power packages to precision resistors with Kelvin connections and resistor networks. This ensures high measurement accuracy and controlled power dissipation in power supplies, driver stages, battery applications, and advanced test equipment.
When every ppm counts, our precision and ultra‑precision resistors offer tolerances down to 0.01%, very low temperature coefficients, and resistance ranges up to 100 MΩ. Ideal for reference circuits, precision amplifiers, and test and measurement systems where long‑term stability is essential.
Our precision networks provide extremely stable resistance ratios with ratio tolerances down to 0.01% and low ratio TCR. This includes everything from voltage dividers and current sensing networks to custom SIP networks – ideal for high‑resolution instruments, multirange meters, and sensitive analog stages.
For environments with extreme heat, we offer resistors capable of continuous operation up to +275 °C, available in precision, power, and low‑ohmic variants. They are designed for geophysics, aerospace, and heavy industry, where reliable performance under high thermal stress is business‑critical.
Our high voltage resistors combine very high resistance values – up to 10,000 MΩ – with low temperature coefficients and high precision. They are used in high‑voltage power supplies, medical equipment, and test and measurement instruments where leakage currents, stability, and safety must be tightly controlled.
High voltage networks make it easy to measure, divide, and monitor voltages up to 20 kV with high accuracy. These include precision and ultra‑precision voltage dividers as well as transient‑protected networks for energy metering and power quality monitoring – essential building blocks for robust measurement systems and power distribution.
Our SMT resistors cover everything from low‑ohmic solutions for current sensing to high‑ohmic precision chips and D‑Pak power resistors up to 25 W. With multiple package sizes and tight tolerances, you can combine high packing density with accuracy and power capability in modern electronics platforms.
When protection, precision, and compact design must go hand in hand, we offer custom resistor networks. The LC2000 series handles lightning and surge pulses and can be equipped with thermal protection or thermistors, in solutions that meet GR‑1089‑CORE and ITU‑T K.20 requirements.
