Metal Strip chip high Power Low Ohmic Resistors (LRP)

Things go better with DeMint (LRP) high power metal strip resistors.

(LRP) Low ohm metal strip resistors from DeMint Electronics offer a wide range of high-power current sensing applications including power management of NB, MB and monitor, automotive, shunts and power amplifiers, DC-DC converter and charger, test & measurement instruments, linear power supplies and switching.

(LRP) Design for applications that require high power handling (Up to 3W) and low resistance values from 7mΩ to 100mΩ and come with a range of advantages including a wide temperature range and a varied choice of wide range package sizes 2512 with high current capability.

DeMint (LRP) is aiming for very high power-to-footprint size ratio, excellent frequency response and very low inductance in a solid metal nickel-chrome or manganese-copper allow resistive element with Low TCR ±50PPM/°C. Also, ideal for all types of voltage division, current sensing and pulse applications.
