Chip inductors, also known as power inductors, high-current inductors, and surface-mounted high-power inductors.It features miniaturization, high quality, high energy storage and low resistance.
How does SMD inductor measure inductance?
Two types of inductance measurement instruments: RLC measurement (resistance, inductance and capacitance can be measured) and inductance measurement instrument.
Measurement of SMD inductance method/step:
1. Be familiar with operating rules (instructions) of the instrument and matters needing attention.
2. Turn on the power and prepare for 15-30 minutes.
3. Select L file to measure the inductance.
4. Clip the two clips and reset them.
5. Clamp the two clips on both ends of the inductance, read the value and record the inductance.
6. Repeat steps 4 and 5 to record the measured values.You have to have five to eight pieces of data.
7. Compare several measurement values: if there is no significant difference (0.2uh), take its average value and remember the theoretical value of inductance;If the difference is too large (0.3uh), repeat steps 2-6 until the theoretical value of inductance is obtained.
Notes:
Different instruments can measure the inductance parameters have some differences.Therefore, before doing any measurement, familiarize yourself with the measuring instrument, understand what it can do, and then follow the instructions it gives you.
