Thin Film on Silicon 2CFA Tapped RC Filter
General Information
Package Schematic
Tapped Filters are typically used for filtering EMI and RFI on
high-speed data lines connecting computer with peripheral.
These Silicon-based, Tantalum Nitride resistors and
capacitors feature excellent stability, temperature coefficients
and tracking performance. This product series conforms to
JEDEC standards.
