The dimensions differ in consideration of the Q characteristics.
<Difference between LQH32C series and LQH32P series>
LQH32P series: This series has a closed magnetic circuit structure coated with a magnetic particle resin.
Therefore, the generated magnetic flux does not leak out so easily, and is not affected by the land.
LQH32C series: Since there is more magnetic flux leakage in this series compared to the LQH32P series, the Q characteristics may deteriorate after mounting due to affects from the land.
Therefore, the land dimensions were reduced to decrease the effect from the land.
