Use high-frequency circuit according to the circuit characteristics: the smaller the better distribution parameters should be used in metal film resistors, metal oxide film resistors and other high-frequency resistance. Low frequency circuits: winding resistance, carbon film resistors are applicable. Decoupling circuit, filter circuit: The change in resistance is not strictly required, any type resistors are applicable. Power amplifier, bias circuit, sampling circuit: circuit stability requirements are relatively high power ptc resistance, temperature coefficient should be selected resistor. Selected according to the choice of resistance resistor values ??and error: the principle is the nominal resistance of resistors and resistor values ??required for the difference between the smaller the better. Selection error: error RC time constant circuit required resistors as small as less than 5% of the general optional decoupling circuit power thick film resistors, the feedback circuit filter circuit load circuit is not too high error Optional 10%. -20% resistor. According resistor limit parameter selection Rated voltage: When the actual voltage exceeds the rated voltage resistance, even to meet the power requirements of the resistor will be breakdown. Rated power: The selected resistor power rating should be greater than the actual power to bear more than double in order to ensure long-term reliability of the resistor circuit to work in. Product Description: Nanjing Electronic produced a series of high-power wound resistors include DDR winding resistance, DQR corrugated wound resistors, DSR adjustable winding resistance. Depending on different occasions and different people's habits, also called ceramic wound resistors, ceramic tube resistors, power resistors, ripple resistance, brake resistance, braking resistance, corrugated resistors, charging resistors, discharge resistors, discharge resistors current limiting resistor, aging resistance or load resistance .DR series winding resistance is one of the core products Zhengyang Hing, high-power, high impact, fast heat dissipation, high stability, long life, fast delivery and so on.
