• Introduction
  • The LHL10TB121K, or KEL10TB121K, is a fixed inductor that is generally used in electronic applications. This component has a nominal inductance of 1.21 mH, a saturation current of 79.5 mA, and a tolerance of up to ±20%. It is considered to be a relatively basic component that can be used in many different types of applications, such as voltage regulators, motor drives, audio amplifiers, and more.
  • The LHL10TB121K is designed specifically for surface mounting on printed circuit boards and is constructed with an epoxy-encapsulated body. The component is made to have a reliable performance and is also resistant to dust and other corrosion-causing substances.
• Application Fields
  • The LHL10TB121K is most commonly used for voltage regulation applications, as it is able to provide a stable and constant current in order to maintain a fixed voltage output. This is especially useful for applications that require a low output ripple such as switched-mode power supplies (SMPS). It is also suitable for use in motor drives and other power-stabilizing systems.
  • The LHL10TB121K is also a popular choice for audio amplifiers, as it\'s able to handle a high signal current without degrading the signal-to-noise ratio. This makes it an ideal component for sound systems as it ensures that the audio signal is not distorted.
  • The LHL10TB121K can be also used in radio frequency (RF) applications, as its high saturation current makes it suitable for use in HF and VHF circuits. It also has a low self-resonance that makes it suitable for use in RF filters and RF amplifier circuits.
• Working Principle
  • The working principle of a fixed inductor such as the KEL10TB121K is relatively simple. When a varying current passes through the inductor, the magnetic core inside it creates a varying magnetic field, which in turn induces a varying voltage across its terminals. This varying voltage, known as an induced voltage, is proportional to the rate of change of the applied current and is equal to the product of the inductance and the rate of change of the current.
  • The amount of induced voltage generated is determined by the value of the inductor. Higher values of inductance yield higher induced voltages, while lower values yield lower induced voltages.
  • The maximum amount of current that can pass through an inductor before it saturates is determined by its saturation current. The saturation current of the LHL10TB121K is 79.5 mA, meaning that it can handle up to 79.5 mA of current before it begins to saturate. This is an important consideration when selecting an appropriate inductor for a given application.
• Conclusion
  • The LHL10TB121K is a fixed inductor that is commonly used in electronic applications such as voltage regulation, motor drives, audio amplifiers, and radio frequency applications. It is designed specifically for surface mounting on printed circuit boards and is constructed with an epoxy-encapsulated body. The component has a nominal inductance of 1.21 mH, a saturation current of 79.5 mA, and a tolerance of up to ±20%. The working principle of a fixed inductor is relatively simple; when a varying current passes through it, an induced voltage is generated proportional to the rate of change of the applied current.
