New LRMAP1216 Resistor for Precise Current Measurement in High-Power Systems

TT Electronics has launched new resistors, the LRMAP1216. It offers compact and surface mount technology (SMT) and is AEC-Q200 approved. They are designed for the precise and reliable measurement of current in high power systems. They are ideal for motor control systems, power supply, Battery Management Systems (BMS).

The LRMAP1216 comes with high power handling up to 5 watts and is ideal for measuring high currents in applications. Their resistance value is low 500 µΩ with 0.5% tolerance and temperature coefficient of resistance (TCR) as low as 50 ppm/°C. This will simplify the designs as there will be less need for additional circuits while measuring. The resistor can even tolerate an overload of up to 25 watts for 5 seconds and is thus resilient to short periods of current surge.

Features of LRMAP1216

• High Power Handling up to 5 watts
• Resistance values as low as 500 µΩ 
• Can handle a short-term overload of up to 25 watts for 5 seconds

Applications of LRMAP1216
