Regarding the manufacturer of 0402 encapsulated alloy resistors, information is relatively limited based on current search results. I have found a clear manufacturer for you and integrated some other possible manufacturers, hoping to be helpful to you.
Clear 0402 alloy resistor manufacturer
According to the searched data table information, Walter Electronics provides the 0402 packaged alloy resistor series.
Product series: MSTC series.
Main features: This type of resistor is usually used for current detection and has the characteristics of low resistance, high accuracy, and low temperature coefficient. Huade's 0402 alloy resistor series covers a resistance range of 1m Ω~50m Ω, with an accuracy of ± 0.5% or ± 1%, and a rated power of 0.25W (1/4W).
Other possible manufacturer references
Alloy resistors are a sub segment of the resistor market, and many well-known resistor manufacturers may offer 0402 packaged products, but the specific product series needs to be further verified by you.
Here are some brands that appear in search results and are active in the 0402 packaged resistor market, with a high likelihood of producing alloy resistors:
YAGEO (Guoju): A globally renowned passive component manufacturer with a wide range of products. Multiple 0402 resistors of this brand appear in search results, but the specific series of its alloy resistors needs to be confirmed on the official website.
Vishay: There is a 0402 thick film resistor from this brand in the search results. Vishay also has a strong product line in the field of precision alloy resistors, which is worth paying attention to.
TE Connectivity: A global company specializing in connectivity and sensing solutions, as well as providing high-precision thin-film resistor products.
How to further search
Due to the fact that "alloy resistors" are a general term, different manufacturers have different names for their product series, making it difficult to find all manufacturers at once through a universal search engine. We suggest that you obtain more accurate and comprehensive information through the following methods:
1. Visit the manufacturer's official website: directly access the official websites of companies such as Huade, Guoju, and Weishi mentioned above.
2. Use professional platforms to screen: Screen on the websites of large electronic component distributors such as DigiKey, Mouser, Element14, etc. You can directly search for "alloy resistor" or "current sense resistor", and then select the "0402" package in the filtering criteria. The system will list all available brands and specific models, which is the most efficient method.
I hope the above information can provide you with valuable reference. If you have more specific requirements for 0402 alloy resistors with specific resistance values or accuracy ranges, I would be happy to assist you in further exploration.
