The TE Connectivity FSK-23A is an economical, dual-contact, surface-mount microfilter designed for use in professional communication equipment. This electrical component is designed to reduce EMI (electromagnetic interference) and protect signal integrity. It provides excellent isolation, low parasitic capacitance, and an extended operating frequency range of 10MHz to 250MHz. The FSK-23A features two identical filter networks, each consisting of two resistors, and a single cap. The filter can be installed in any orientation, and features an ultra-small form factor for easy integration into circuit designs.
