Walter resistors are products launched by Suzhou Walter Electronics Co., Ltd., known for their high reliability, high precision, and diverse packaging specifications. The following is a detailed introduction to them:
CHARACTERISTICS
High reliability: Huade resistor products have high reliability, exceeding the 2000 hour US military standard Mil-202 and Method 107G testing standards, and can work stably for a long time in harsh environments.
High precision: Some products can achieve an accuracy of ± 0.01%, which can meet the strict requirements of precision electronic circuits for resistance values.
Diversified packaging specifications: Huade resistors offer a variety of packaging specifications, such as 0201, 0402, 0603, 0805, 1206, 2010, 2512, etc., to meet the needs of different application scenarios.
Low temperature coefficient: The temperature coefficient is usually around ± 50ppm/℃, and the resistance value has little effect on temperature changes, which can ensure the stability of the circuit in different temperature environments.
Low electric couple effect: Some products have an EMF<0.5uV/℃, further improving the accuracy and stability of the resistance.
