DeMint Electronics provides a wide range of precise shunts designed for high current applications requiring high precision, such as instruments, power supplies, watt-hour meters, automotive control systems, etc.
As one of current sensing resistors, metal plate alloy shunt resistors are precise low resistance which are often used in AC or DC voltage measurement. They are also called ammeter shunts.
The FLP shunt is composed of precise manganese kamar alloy plate, which is easy to weld and ensures the electrical performance of the welding joint. Strong structure provides high reliability, low inductance, and high load capacity. It is widely used in current limiting circuits such as communication systems, electronic machines, automatic control power supply, and current sharing or sampling detection.
Metal Plate FLP shunts can withstand higher current load than traditional resistors and surface mount resistors. Its power can reach 3W~70W, temperature coefficient ±50ppm/ °C, ±100ppm/ °C, inductance is less than 10 nH, resistance is as low as 0.00005Ω, tolerance accuracy ±1%, ±2%, and ±5%, and overcurrent capacity can reach 100A~600A.
DeMint provides bulk FLP series, which meets the lead-free and RoHS compliant. It can be customized according to customer's needs and provide customers with lower resistance series current sensing shunt resistors.
