BXN11508-G1

The BXN series from DENSO includes both sintered and press-fit types. For the sintered models, the heat sink heat sinks are primarily made of copper, though lower power versions may use aluminum or iron. While various models share a similar appearance, their outer diameters vary. In contrast, the press-fit models feature aluminum heat sinks. Although they have a similar appearance, differences in stator wire welding methods and overall shapes distinguish them from each other. Copper heat sink heat sinks in the BXN series offer superior thermal performance compared to other materials. These heat sinks are nickel-heat sinkd for durability and do not require special protective coatings. The assembly is secured with iron rivets. The Toyota series, notable for its distinctive "drumstick" appearance, is easily recognizable. It features heat sinks made of either copper or aluminum. The design does not include excitation tubes, resulting in a streamlined structure with fewer components, which enhances reliability and performance.
