Yihao Electronic is one of the professional enterprise offering thermistor, humistor, temperature sensor and measuring methods also. We have years experience in producing thermistor series. The main pattern of our thermistor is glass encapsulation, such as diode form, diode patch and single-ended glass encapsulation. In our country, only two companies can manufacture the single-ended glass encapsulated products stably. The thermistor parameters of ours can satisfy differing measured conditions. 5K or 10K is used in the low temperature region, such as refrigerator, air condition, electrical calendar, water heater etc. 47.5K, 50K, 57.5K and 100K are used in the middle temperature region, such as water boiler, induction cooker, electric pressure cooker etc. 230K and 1000K are high B value products of high sensitivity in high temperature measurement, used in baking oven or microwave oven. By the meanwhile, our temperature sensor can be used in kinds of household appliances, such as refrigerator, air condition, water heater induction cooker etc. We can design various special parameters products as the demands of customers. In the temperature protection, we offer the self-restoration fuse which widely used in battery over-current protecting circuit. Our thermistors satisfy ROHS commands and the environment protection requirements of EU. Whether offering the ROHS commands or not, depends on the customers. We look forward to have cooperation with you.
