1206J1000221MCTE01

Overview

The Knowles Syfer 1206J1000221MCTE01 is a three-terminal surface-mount EMI filter capacitor designed for high-frequency noise suppression. It features a C0G (NP0) dielectric material providing stable capacitance characteristics across varying temperatures and voltages. The component operates within a DC voltage rating of 100V and offers a nominal capacitance of 220pF with a tolerance of ±20%. Housed in a standard 1206 (3216 metric) package, it supports operation from -55°C to +125°C. This device integrates feedthrough technology to minimize parasitic inductance, ensuring effective signal integrity in sensitive electronic circuits.
