Open Air Resistor, Metal Element Current Sense, Low Ohm

Current sense open air resistors are expected to gain wide acceptance in the worldwide market as a result of increased thermal management capabilities.

The FLQ series is designed for applications requiring the transfer of heat away from circuits and solder joints. Available in 0.5W, 1W, and 1.5W rating, the resistor is being specified for current sensing, feedback, current detective, supper low inductance, as well as surge and pulse applications.

The hot spot on the open-air resistor is approximately 0.2 degrees higher than on a typical metal strip chip resistor. This results in an increased thermal path for the FLQ, reducing heat transfer into the solder joints and circuits.

The flameproof FLQ low resistance value resistors are constructed of a wire resistive element with welded copper leads to prevent solder wicking, which can change the device's resistance value in the circuit by as much as 30%. Because of this, the device is ideal for thermally harsh environments, including automotive and aerospace applications, as well as enclosed, poorly ventilated circuits in applications such as laptop computers.

Features:

• Radial leads.
• Non-inductance.
• Solderable Copper Leads.
• Lead (Pb)-free and RoHS compliant.
• ±1%, ±2%, ±5% standard tolerance.
• High stability bare metal element open air style.

Applications:

• ​Automotive Current Sensing, Feedback System.
• CPU Drive Control, Power Tool Motor controls.
• Power Supply Shunt, Current Detective.
• Inverter and Switching Power Supplies
• Residual Battery Power Detection.
• High power AC/DC detection.

Jingdacheng Electronics(JDC) is a leading power resistors manufacturer in China, and we are always focusing on providing various resistors and loading solutions since it was established in 1997. With 24 years industry experiences, JDC has a professional team for resistor designing, manufacturing and quality control, and most of our managements have been working for JDC at least 10 years. Even approved by ISO9001:2014, JDC started proceeding a very high standard (Japan JIS) of manufacturing and quality inspection since we built a long partner cooperation with Japan IWAKI MUSEN in 2013. Now, JDC is providing many resistors and solutions for some top500 companies, Such as: Huawei, Yaskawa, Panasonic, Midea, etc.
