Chip Coils
for General Use Magnetic Shielded Type LQH3ER Series
s
Features
The LQH3ER series consists of magnetically shielded
chip inductors. Its tight inductance tolerance of +-2%
enables no adjustment of circuit. The shielding
structure eliminates external interference and
facilitates high mounting density.
