Hộp điện trở chuẩn Batemika R210A
R210A series of reference resistors present an accurate and stable source of electrical resistance at an affordable price. R210A resistors are based on a Vishay VHP101 hermetically sealed foil resistive element, which provides superb short-term and long-term stability, as well as a fair level of immunity to mechanical and electrical stress. R210A resistors feature extremely low temperature coefficient, which enables the use in air at normal laboratory ambient conditions, eliminating the need for additional thermal enclosure.
