As a leading enterprise in the field of electronic components, LIZ Electronics has a wide range of resistor product lines and has designed multiple types of high-performance resistors for different application scenarios. The following categories introduce its core products and features:
Thick film surface mount resistor
Lizhi's thick film surface mount resistors are known for their high precision and stability, and are mainly divided into two series:
CR series: using thick film technology, the resistance range covers milliohms to megaohms (such as 200m Ω± 5% for 1210 package to 2.8M Ω± 1% for 0805 package), with an accuracy of ± 1% and a temperature coefficient as low as ± 100ppm/℃. Suitable for general circuit design, such as consumer electronics, communication devices, etc.
CH series: designed specifically for high power requirements, with resistance as low as 0.33 Ω and power up to 0.5W, suitable for high load scenarios such as industrial power management and automotive electronics.
Ultra micro series: Ultra micro surface mount resistors (such as 0201 package) launched in 2024, with a volume reduced by 50% compared to traditional models, suitable for smart wearable devices and high-density circuit boards.
Alloy resistance
Alloy resistors are characterized by high power carrying capacity and high temperature resistance. For example, the 2512 R050 surface mount alloy resistor has a power of up to 2W and a resistance accuracy of ± 1%. It is suitable for current detection, power modules, and other scenarios that require precise current limiting. Its material has anti vibration and high temperature resistance characteristics, and can work stably in an environment of 55 ℃~125 ℃.
Anti sulfurization resistor
Designed for harsh environments, sulfur resistant resistors are treated with special processes to effectively resist corrosion from sulfur-containing gases, making them suitable for applications such as chemical and outdoor equipment that are prone to corrosion. Its long-term stability is significantly better than ordinary resistors, making it suitable for industrial equipment with high reliability requirements.
High voltage resistor
Lizhi's high-voltage thick film surface mount resistors can withstand voltages ranging from 500V to 10kV, with excellent insulation performance, and are suitable for high-voltage environments such as power transmission equipment and photovoltaic inverters. The product combines high precision (such as ± 1%) and fast response characteristics, effectively preventing circuit failures caused by overvoltage.
Varistor
As the core component of circuit protection, Lizhi varistors are divided into multiple subcategories:
Universal type: suitable for household appliances and lighting equipment, with strong impact resistance.
High energy type: capable of withstanding high-power surge impact, used for industrial equipment and power systems.
Surface mount type: compact in size (such as 1206 package), suitable for high-density circuits such as mobile phones and computers.
Low leakage current type: With extremely low leakage current, it meets the stringent requirements of medical equipment and precision instruments.
Accuracy up to ± 0.5%, temperature coefficient as low as ± 25ppm/℃, suitable for high-precision scenarios such as voltage divider circuits and measuring instruments. For example, the 1k8 Ω resistor packaged in 0603 (with an accuracy of ± 5%) is widely used in consumer electronics and industrial control.
Vehicle grade resistor
Compliant with AECQ200 standard, with a temperature resistance range of 55 ℃~125 ℃ and strong anti vibration performance, specially designed for automotive electronics, such as in car control systems, sensors, etc.
