Large Diameter Solder-In High Temp EMI Filters
Large diameter solder-in, high temperature EMI 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.
Spectrum Control offers a variety of Solder-In EMI Filters.
- .400” diameter mounting vs .128” diameter mounting
- Increased capacitance values - up to 1.2µF
- EMI filtering from 500KHz up to 10GHz
- 15 amp current rating
- Glass sealed one end provided protection from hostile environments and maintain hermeticity
- Rugged monolithic discoidal capacitor construction
- High-temperature construction withstands 300°C installation temperatures
- Gold plated suited for gold bonding
- EMI filter designed to be soldered into a package, bracket or bulkhead
- Reverse seal available
- Special lead length and end terminations available
- Ideal for low to medium impedance circuits where large amounts of capacitance to ground can be tolerated (feedthrough "C" circuit)
- Microwave attenuators
- Microwave oscillators
- High impedance circuits where large capacitance values are not practical
- Signal and data lines
- DC power lines
