Chip Weld Precision Resistors (LRN)
For the development of current detection and shunting applications, DeMint's high current shunt (LRN) adopts the welding structure of Manganin and KAMAR (NiCr20AlSi) precision resistance alloys. The spacing standard design makes it easy for surface mounting, reflow soldering, and suitable for current sensing and shunting applications.
Open bare alloy element design allows air flow to achieve maximum cooling effect, so that PCB retains less heat. The design of flame protection structure provides 0.0005Ω low resistance and low inductance. These factors make ruggedness (LRN) an excellent choice for all high current power supply and power applications that are not affected by most environmental stresses.
Specially designed for applications requiring high power processing (LRN). The power is 4W and 7W. The ultra-low resistance ranges from 0.5mΩ to 30mΩ. There are various tolerance selection advantages (±1%, ±2%, ±5%) , size 4312, and 4320. To achieve compact size and miniaturization, design a smaller, lower cost, higher performance, high power circuit terminal product design.
Provide packing with Embossed Plastic Tape, size 4312 2Kpcs per reel, 4320 2Kpcs per reel, products meet the lead-free and RoHS standards. Customers can specify resistance, size and specifications to meet the design challenges and specific technical requirements. Please contact DeMint Business Department for the latest product information.
