Square Patch Coil E4 series square hollow inductor, the welding part is higher than the product body,which is more convenient for product soldering and reduces soldering defects.The top design is flat, the inductance is 3.3nH--40nH, the carrier tape is mounted,and the automatic chip production, inductance.The accuracy of 2% and 5% is optional. It is always our development direction to develop better products.
