Large Diameter Solder-In High Temperature EMI Filters

Low Pass Filters

Large Diameter Solder-In High Temperature Filters can withstand 300°C installation temperatures. These EMI filters are ideal for low to medium impedance circuits where large amounts of capacitance to ground can be tolerated.

PRODUCT SOLUTIONS
