What are the categories of Panasonic resistors?

As a globally renowned comprehensive electronic technology enterprise, Panasonic's resistor product matrix covers a diverse range of scenarios from basic circuits to high-end industrial applications, and can be classified into the following six core categories:
1. Surface mount resistor (SMD resistor)
High heat-resistant surface mount resistor: using special materials and processes, it can work stably in a wide temperature range of -65 ℃ to+175 ℃, suitable for high-temperature scenarios such as automotive electronics (such as car inverters) and industrial control (such as motor drives).
High precision surface mount resistor: With an accuracy of ± 0.05% and a temperature drift as low as ± 10ppm/℃, it meets the precision measurement needs of medical equipment (such as electrocardiographs) and communication equipment (such as 5G base stations).
Chip resistors for current detection: low resistance (0.5m Ω to 910m Ω) combined with high precision, designed specifically for power management (such as battery management system BMS) and electric tools.
Small high-power surface mount resistor: reduces volume by 30% while achieving a 5W power density, suitable for space limited scenarios such as consumer electronics (such as smartphones) and drones.
Sulfurization resistant surface mount resistor: Resists corrosion in sulfurized environments through special coatings, suitable for harsh industrial environments such as chemical and mining.
Universal SMD resistors: covering standard sizes from 0402 to 6432, meeting the basic circuit requirements of household appliances (such as air conditioners) and consumer electronics (such as televisions).
SMT resistor placement: Integrating multiple resistors into one simplifies circuit board design, improves production efficiency, and is widely used in computers and communication equipment.
2. Plug in resistor (THT resistor)
Pin resistance: Traditional plug-in design, suitable for manual welding and maintenance scenarios of industrial equipment (such as PLCs) and old-fashioned household appliances (such as cathode ray tubes and televisions).
Thermistor (discontinued): Once used for temperature detection, it has gradually been replaced by NTC/PTC sensors.
Adjustable resistor (discontinued): Initially used for circuit debugging and calibration, now mostly replaced by digital potentiometers.
3. Special function resistors
Attenuator: Used for signal attenuation and impedance matching to ensure stable operation of communication equipment (such as RF modules) and testing instruments (such as oscilloscopes).
Chip ring (chip signal detection terminal): specially designed for high-speed digital circuits to enhance signal integrity, applied in scenarios such as servers and switches.
4. Classified by materials and technology
Carbon film resistor: Low cost, average stability, suitable for general consumer electronics (such as radios).
Metal film resistor: High precision (± 1%), good stability, widely used in precision circuits (such as instruments).
Metal oxide film resistance: high temperature resistance (up to 450 ℃), strong overload capacity, suitable for industrial control (such as frequency converters) and power management (such as switch mode power supplies).
Thin film resistor: using vacuum deposition technology, with an accuracy of ± 0.1%, small size, suitable for high-end consumer electronics (such as VR helmets) and automotive electronics (such as ADAS controllers).
Thick film resistor: With high power (up to 10W) and low cost, it is widely used in household appliances (such as refrigerators) and industrial equipment (such as welding machines).
Alloy resistor: low resistance value (starting from 0.5m Ω), high precision (± 1%), specially designed for current detection, applied in battery management systems (such as Tesla Model 3) and power modules (such as server power supply).
5. Classification of application fields
Automotive Electronics: Passed AEC-Q200 certification, suitable for in car inverters, battery management systems (BMS), and body control modules (BCM).
Industrial control: high heat resistance, high-power resistor, suitable for motor drive, power management, factory automation (such as PLC, robots).
Consumer electronics: miniaturized, high-precision resistors suitable for smartphones, tablets, and smart home devices (such as smart speakers).
Communication equipment: high-frequency, low loss resistor, suitable for base stations, routers, and optical modules (such as 5G optical communication).
In the field of energy: corrosion-resistant and highly reliable resistors, suitable for solar power generation systems and energy storage inverters (such as Panasonic and Tesla cooperation projects).
Technical advantages and certification
High precision and low temperature drift: such as ERA * V/K/P series thin film resistors, with an accuracy of ± 0.05% and a temperature drift of ± 10ppm/℃, meeting the demands of the high-end market.
ESD resistance and solder resistance: Special processes enhance resistance to static electricity (up to 8kV) and solder stress, improving production yield.
Corrosion and vulcanization resistance: using special materials and processes to resist harsh environmental corrosion and extend product life to more than 10 years.
High heat resistance and high power: By optimizing materials and design, the resistance heat resistance (up to 175 ℃) and power processing capability (such as 5W miniaturization design) are improved.
Application area coverage
Automotive Electronics: Panasonic resistors are widely used in battery management systems and electric compressor controllers for companies such as Toyota and Tesla.
Industrial control: compatible with Siemens and Mitsubishi Electric's PLC and AC servo drives to assist in factory automation.
Consumer electronics: entering the supply chain of Apple and Huawei, used for power management modules for smartphones and tablets.
Communication equipment: Provide high-frequency resistors for 5G base stations for Huawei and ZTE to ensure signal stability.
Energy sector: Collaborate with Panasonic's own battery business to provide high reliability resistors for solar inverters and energy storage systems.
