Detailed explanation of various resistors
1. Thin film resistors: representatives of high precision and high performance
Guangjie's thin film resistors are known for their excellent precision and stability. The AR series is a benchmark for precision applications, with tolerances as low as ± 0.01%, temperature coefficient (TCR) up to ± 5 ppm/℃, and size coverage ranging from tiny 0201 to larger 2512. For circuits that require operation at high frequencies, such as communication and radar equipment, the ARF series is designed specifically for ultra-high frequency circuits, supporting operating frequencies up to 70GHz. In addition, there are ARN series with aluminum nitride substrate and excellent heat dissipation performance, RAM series with sulfur resistance, and TAR and PR series that have passed strict automotive testing to meet the requirements of harsh environments such as automobiles and industries.
2. Metal film resistors: a combination of reliability and high-frequency applications
Metal film resistors, especially the MELF (cylindrical) package series, exhibit excellent reliability and special performance. For example, the CSRV series complies with the AECQ200 automotive standard, has high precision, and is suitable for precision current detection scenarios such as automotive battery management systems. The CSRF series is optimized for high-frequency applications, with low insertion loss in the 5GHz frequency band, making it suitable for devices such as 5G communication modules.
3. Alloy resistance: the core of high current detection
In situations where high currents need to be measured or controlled, the alloy resistance of Guangjie is a key component. The LR series is made of special alloy integrated molding, with a resistance as low as 0.5m Ω, almost no inductance, and has a rated power of up to 3W and good TCR. It is widely used for current detection in power supplies, inverters, and automotive electronics. For sampling scenarios with higher precision requirements, the LRP series can be chosen.
4. Thick film resistors and other power type resistors
Thick film chip resistors (such as CR series) are the most widely used general-purpose resistors with a wide range of resistance values and high cost-effectiveness. When the circuit needs to handle higher power, the TR series plug-in power resistors provided by Guangjie (such as TO220 package) can reach a power of 20W to 100W and are commonly used in UPS, power equipment and other fields.
5. Resistors designed for special environments
Guangjie also produces resistors specifically designed to cope with harsh environments. For example, the AS series sulfur resistant resistors can effectively prevent corrosion failure caused by sulfur-containing environments such as industrial areas and hot spring areas. The HVR series high-voltage resistor can withstand thousands of volts of overload voltage and is used for high-voltage voltage division detection. The SWR/PWR series has strong surge resistance and can provide protection for circuits such as motor control that are susceptible to voltage surges.
How to choose a photoelectric resistor
In actual selection, you can follow the following approach:
Clarify core requirements: Firstly, determine the primary requirements of the circuit for the accuracy, power, resistance range, and temperature stability of the resistor.
Consider the work environment: Determine whether there are special factors such as high frequency, high voltage, high humidity, sulfur-containing, or high impulse current in the application environment, and select the corresponding series based on these characteristics.
Reference packaging and size: Select the appropriate packaging size based on the spatial layout of the circuit board (such as 0201, 0402, 0603, 2512 and other surface mount packaging, or TO220 plug-in packaging).
Utilizing official resources: It is recommended to refer to the detailed selection guide and data manual provided by Guangjie official or authorized agents to obtain the most accurate parameter information and the latest product updates.
I hope the above information can help you fully understand Guangjie's rich resistor product line. If you could share specific application scenarios (such as automotive battery management, communication RF circuits, or industrial power supplies), perhaps you could provide more focused selection recommendations.
