Thick film chip resistors: the cornerstone of the most widely used applications
Lizhi Electronics' thick film surface mount resistors are the core of its products, which have been optimized through different materials and processes to derive multiple sub series to meet specific needs.
Universal thick film resistors (such as CR series): This is the most basic series, manufactured using thick film technology, with a wide range of resistance values. It has a complete range of packaging sizes, covering everything from ultra small 0201 to high-power 2512, and is widely used in general circuits of various consumer electronics and communication devices.
High voltage and surge resistant resistors: For high voltage environments, Lizhi's RC series high-voltage thick film resistors can withstand voltages ranging from 500V to 10kV, with excellent insulation performance, and are commonly used in power transmission equipment and photovoltaic inverters. The RS series anti surge resistor focuses on resisting instantaneous high voltage impact, protecting circuit safety, and is suitable for scenarios such as power switches and motor controllers.
Low resistance and power type resistors: In situations where precise current measurement is required, such as battery management systems (BMS) for new energy vehicles, Lizhi's UR/LZI series low resistance resistors are key components, with resistance values as low as 0.1m Ω and high accuracy. For applications that require greater current carrying capacity, the CH series or RW series with wide electrode design provide better heat dissipation and power levels.
Alloy resistance: a representative of high power and high stability
Lizhi's alloy resistors are made of metal alloys and are known for their high power carrying capacity and excellent high-temperature and vibration resistance characteristics. For example, a 2512 packaged surface mount alloy resistor can achieve a power of up to 2W and a resistance accuracy of ± 1%. This type of resistor is particularly suitable for precise current detection and limiting in power modules and motor drives, and can maintain stable operation even in harsh environments.
Circuit Protection Expert: Varistor
Lizhi's varistors are mainly used to protect circuits from damage caused by voltage surges. Its product line is finely divided, including general-purpose models for household appliances, high-energy models for power systems, micro patch models for mobile phones and computers, and low leakage current models with strict limitations on leakage current (applicable to medical equipment). Users can choose according to different overvoltage protection requirements and installation space.
Special resistors for special environments
In order to meet the reliability requirements of industries, automobiles, and other fields, Lizhi has developed various special resistors.
Sulfur resistant resistor: Through special processing, it can effectively resist the corrosion of sulfur-containing gases and significantly improve long-term stability in harsh environments such as chemical and outdoor environments.
Precision resistor: Provides an accuracy of up to ± 0.5% and a temperature coefficient as low as ± 25ppm/℃, designed for applications that require high precision such as measuring instruments and voltage divider circuits.
Vehicle grade resistors: These products comply with the AEC-Q200 standard established by the Automotive Electronics Council, and can operate stably in a wide temperature range of -55 ℃ to 125 ℃, with stronger anti vibration performance, specifically designed for automotive electronic systems.
Adjustable resistor: a flexible control solution
The adjustable resistors of Lizhi (sometimes labeled as LZI) provide flexibility for circuit debugging and parameter adjustment. Its types include finely tuned precision multi turn adjustable resistors, cost-effective single turn carbon film adjustable resistors, patch type adjustable resistors suitable for modern surface mount technology, and ceramic, waterproof, and high-power adjustable resistors suitable for high temperature, outdoor, or high-power scenarios.
How to choose the appropriate Lizhi resistor?
When choosing a Lizhi resistor, you can start with the following key parameters:
1. Resistance and accuracy: Determine the required resistance value and error range for the circuit (such as ± 1%, ± 5%).
2. Power and size: Calculate the required rated power based on the operating current of the circuit, and select the appropriate packaging size accordingly (such as 08051206).
3. Special environmental requirements: If the application environment contains high voltage, surges, corrosive gases, high humidity, or severe vibrations, the corresponding high voltage, surge resistance, sulfurization resistance, waterproofing, or vehicle grade series should be given priority consideration.
4. Functional requirements: Clarify the role of resistors in circuits, whether they are used for ordinary current limiting, precision detection, voltage division, or circuit protection, in order to narrow down the selection range.
I hope this introduction about the categories of Lizhi resistors can help you. If you could share specific application scenarios, such as being used in power supply design, automotive electronics, or a certain consumer product, perhaps I can provide more specific selection suggestions.
