Introduction to RALEC resistor products
Company Overview
Established in 1994, RALEC, headquartered in Taiwan, China, China, is a manufacturer of chip resistance, resistance removal (network array resistance) and metal plate current detection resistance under Chilisin Group. The company focuses on technological innovation and has four major production bases in Kaohsiung, Taiwan, Kunshan, China, Yuanling, Hunan, and Malaysia. In 2017, it merged with Qilixin Group and further strengthened its research and development capabilities and global layout.
Core product series
Wangquan's resistor product line covers a wide range, mainly including the following types:
Alloy resistance:
Vehicle series: such as LRS (four terminal alloy current sensing resistor), LR-A (metal micro alloy resistor), LRH-A (low sensitivity alloy resistor), etc., designed specifically for automotive electronics to meet high reliability requirements.
Universal series: such as LR series (standard metal alloy resistor), LRE (miniaturized alloy resistor), LR4 (four terminal metal alloy resistor), etc., suitable for industrial, communication and other fields.
Barrier (network array resistor): used for high-density circuit integration to reduce installation complexity.
Metal plate current detection resistor: low resistance value (can be as low as 0.2m Ω), used for current detection and shunt, supporting high-precision power management.
Technical advantages
Material innovation: Manganese copper alloy, iron chromium aluminum alloy and other materials are used, which have high temperature resistance (oxidation resistance, vulcanization resistance) and anti-aging characteristics.
Low resistance and high precision: The resistance range is as low as 0.2m Ω, with a standard accuracy of 1% and an optional 0.5% high-precision version.
Low temperature drift characteristics: The temperature coefficient is as low as 15ppm/℃, ensuring stability at extreme temperatures.
High power carrying capacity: withstand current greater than 158A, high power density, suitable for high load scenarios.
Packaging technology: using patented copper terminal technology to enhance thermal conductivity and reduce electromagnetic interference (EMF); Thin film packaging technology enhances corrosion resistance and mechanical strength.
Application Fields
Wangquan resistor products are widely used in the following fields:
Automotive electronics: sensors, controllers, battery management systems (BMS), and electric vehicle charging modules.
Communication equipment: Current detection and power management in 5G base stations, routers, and switches.
Industrial automation: industrial sensors, transmitters, and high-precision control equipment.
New energy: energy conversion modules for solar inverters, energy storage systems, and charging stations.
Consumer electronics: Circuit protection and signal processing for devices such as smartphones and computers.
Quality certification and environmental standards
Certification System: Passed certifications such as ISO 9001 (Quality Management), ISO 14001 (Environmental Management), TS 16949 (Automotive Industry Standard), etc.
Environmental compliance: Compliant with RoHS standards, promoting the research and development of lead-free and biodegradable materials.
Market and Supply Chain
Global layout: Products cover the global market through channels of Qilixin Group, and agents in Shenzhen, Kunshan, and other places in China (such as Huaqiu Electronics and Kemeiye Electronics) provide localized support.
Product model example:
The RTT series surface mount resistors (such as RTT063831FTP, RTT032801FTP) come in packages including 1206, SMD, etc., making them suitable for diverse needs.
Precision alloy resistors (such as LR2512-23R00075F4), packaged in 2512, meet the requirements of high-precision current detection.
RALEC has become an important participant in the global resistor market, particularly in automotive grade and high-power scenarios, thanks to its deep cultivation in the fields of alloy materials and precision manufacturing. Its products have high reliability, low temperature drift, and high power density as their core competitiveness, continuously promoting the technological development of cutting-edge fields such as 5G communication, electric vehicles, and industrial automation.
