3、 Special applications and high-performance products
In response to the demands of emerging fields, Sartre has launched differentiated solutions:
High voltage/high temperature fuse:
A fast breaking surface mount fuse with a withstand voltage of over 250V, used for medical equipment and industrial power supplies.
Vehicle grade products:
Certified by IATF16949, such as high-temperature resistant fuses (55 ℃~150 ℃) and alloy resistors, compatible with BMS (battery management system) and OBC (on-board charger).
Ultra low resistance resistor:
Used for current monitoring of 5G base station power supply and server cooling fans.
4、 Panoramic View of Product Application Fields
Sartre products cover the following core scenarios:
Consumer electronics: fast charging for mobile phones, TWS earphones, lithium battery protection for laptops.
New energy and energy storage: photovoltaic inverters, outdoor power sources, energy storage systems (square shell fuse series).
Automotive electronics: electric vehicle BMS, charging station.
Industry and Communication: 5G base stations, servers, industrial power modules.
Sutter Technology takes "fuse+current detection resistor" as the dual main line, and through material innovation (such as graphene arc extinguishing technology patent) and process upgrading (thin film/thick film/alloy stamping), has built a product matrix covering the full scene circuit protection needs. Its technological barriers are reflected in high current density design (such as the 1032 series leading the industry for 2 years) and participation in international standards (leading more than 20 IEC/national standards), becoming a supplier to companies such as Huawei and Purple Mountain Laboratory. In the future, with the increasing demand for new energy and intelligent equipment, Sartre's technological accumulation in the fields of high voltage and high surge resistance will further strengthen its market competitiveness.
