RALEC surface mount resistors have the characteristics of high precision, high reliability, and diverse specifications, and are widely used in the electronics industry. The following is a detailed introduction to them:
CHARACTERISTICS
High precision: Advanced manufacturing techniques are used in the manufacturing process, resulting in minimal differences between the resistance value and the nominal value. For example, some products have an accuracy of ± 0.01%, which enables electronic device circuits to calculate and control current flow more accurately, improving device performance and stability.
High reliability: Using high-quality materials and strict production processes to ensure stability and reliability under various environmental conditions. In harsh environments such as high temperature and humidity, it can still maintain normal working conditions without generating excessive heat or performance degradation due to environmental changes. Its excellent durability enables it to withstand long-term use and various external factors such as humidity, vibration, etc. without compromising performance or lifespan.
Diversified specifications:
Resistance range: ranging from milliohms to megaohms. For example, some alloy surface mount resistors have a resistance range of 0.1m Ω~200m Ω, which can meet circuits with different precision requirements.
Tolerance level: including multiple levels such as ± 1%, ± 2%, ± 5%, etc., to adapt to circuits with different accuracy requirements.
Power range: ranging from tens of milliwatts to several watts, depending on the size and design of the resistor. For example, some surface mount resistors have a rated power of 0.05W (medium power), while some alloy surface mount resistors have a rated power of up to 1W/1.5W/2W/3W/4W.
Temperature coefficient: It reflects the degree of change in resistance value with temperature. Some products have a temperature coefficient as low as ± 15ppm/℃, which can effectively reduce the impact of temperature on resistance value.
Packaging forms: including bulk and roll packaging (such as 2mm Pitch paper tape, 4mm Pitch paper tape, 4mm Pitch tape, etc.) to meet the needs of automated production and manual welding.
2、 Product series
Surface mount resistor series: including conventional thick film, conventional thin film, high-power thick film, high-precision thick film, anti sulfurization thick film, anti surge thick film, anti high voltage thick film, resistor attenuator and other types.
Alloy surface mount resistor series: models include LR1206, LR1210, LR2010, LR2512, LR2527, etc., with features such as increased power, high rated power, ultra-low resistance, high precision, low temperature coefficient, and high heat dissipation performance. For example, the LR series alloy patch resistors have a high rated power, a wide range of resistance values, and a low temperature coefficient, making them suitable for high-power power supplies, inverters/frequency converters, LED driver power supplies, industrial control, medical devices, motors, and other fields.
3、 Application Fields
RALEC surface mount resistors are widely used in various electronic devices with high precision and reliability requirements, such as consumer electronics, automotive electronics, LED lighting, industrial control, medical equipment, LED power supplies, and other fields. In the field of automotive electronics, its high precision and reliability ensure that equipment can operate stably in harsh environments, unaffected by temperature and humidity.
