It’s not easy being a current-sense resistor: so much is expected of this basic function of determining current flow by simple measurement of voltage across a known resistance, then applying Ohm’s Law ...

The CSM3637P ultra-high-precision, surface-mount, four-terminal current sense resistor has been announced with an increased resistance range to 200 mΩ. For power supplies, DC/DC and DC/AC converters, ...

Measuring dynamic current flow has always been an important parameter for managing system performance, and doing so has become even more so with the proliferation of smarter management functions for ...

Vishay has created a 5W 1206 current sense resistor range. Called WSLF1206, it is available in values down to 300μΩ. Only the 300μΩ and 500μΩ versions are rated at 5W, and that is only up to 70°C ...

TT Electronics IRC has developed a series of high-reliability thick film chip resistors tested to MIL-PRF-55342-level specifications. Designated the LRF3W-MIL Series, the resistors are terminated on ...

Stackpole Electronics is pitching its 1W-rated CSSH0805 all-metal 0805-size chip resistor family against 1206 and 2010 parts for current sensing. It comes in three temperature coefficient versions: ...

Current. Too little of it, and you can’t get where you’re going, too much and your hardware’s on fire. In many projects, it’s desirable to know just how much current is being drawn, and even more ...

This resistor with bands of red, violet, yellow, and gold has a value of 270,000 ohms (270kΩ) with a tolerance of ±5%. \( \begin{eqnarray*}\text{R}_\text{t ...
