The MHQ1005P19NJT000 are Fixed Inductors IND 0402 19nH S-HQ SMD RF IND made by TDK. These components have a 0402 case size, 19nH inductance, and operate in a range of 10MHz to 5GHz. They are designed for high Q performance in a range of applications such as wireless power, DC-DC converters, and low noise circuit designs. The high Q gives these components excellent noise immunity and power efficiency. They have very low ESR (Equivalent Series Resistance) values and can handle higher operating temperatures, up to 125 degrees Celsius. These components are provided in a tape & reel packaging, making them an ideal choice for automated assembly lines.
