Current sense resistors are a rapidly evolving technology that focuses on regulating and monitoring power from the power supply to the end equipment.
In addition, current sensing resistors based on DeMint (CSM) metal alloys are capable of handling higher inrush currents, have better TCR capability, and generally do not suffer from differences in thermal expansion from the PCB. Metal alloy based resistors are a cost-effective solution compared to competing technologies including Hall effect sensors, magnetoresistive sensors and current transformers.
DeMint (CSM) provides high performance and reliability over the entire operating temperature range, with a small enclosure size and high power rating compared to standard current sense resistors. Resistance value starts at 1mΩ and goes to 700mΩ, applications include switches and DC-DC converters, battery packs, chargers, adapters, overcurrent protection in audio applications, power management applications, LED drivers, motor control, electric Tools and power amplifiers.
Ultra low resistance metal chip resistors (CSM) are SMD devices designed for current sensing circuits in power electronics systems. The metal alloy construction ensures high reliability and high performance with a very low and stable TCR (50ppm, 75ppm, 100ppm) value. The small chip size provides high power ratings from 0.5W to 5W and operates from -55°C to +155°C temperature. Accuracy tolerances are ±0.5% and ±1%.
There are many options of popular industry sizes: 0603, 0805, 1206, 2010, 2512, 3921, 4527, 0508, 0612, 0815, 1225, and 2139. 5K pcs per reel in smaller sizes 0603, 0805, 1206, 0508, and 0612. 4K pcs per reel for 2010, 2512, 0815, and 1225. 2K pcs per reel for 2139.
Ultra-low ohmic chip resistors (CSM) for current detection meet RoHS standards and lead-free requirements.
