SRF3216A-222Y is a type of common mode chokes. It is designed for applications of common mode noise filtering in power and data lines, mainly used to reduce differential-mode currents interfering with other higher level electronic circuitry.The SRF3216A-222Y common mode choke is an inductor capacitor (LC) circuit consisting of two inductors with similar values of inductance. These inductors are connected in series, with their magnetic fields linked together to form a large effective inductance. An internal capacitor is connected across the inductors in parallel with the inductors. This capacitor is referred to as the "interconnection capacitor", which is the most important component in the SRF3216A-222Y common mode choke.The SRF3216A-222Y common mode choke works by creating a balanced common mode noise filter and is effective at attenuating a range of frequencies, from 100 kHz up to over 1 GHz. This specific common mode choke features inductance of 2.2 uH with a rated current of 2A, an inductor Q (quality factor) of 12 with a parasitic capacitance of 22 pF, and a very low series resistance of only 0.06 Ohms. It operates at maximum temperature of 125°C and uses ceramic housing for better safety.The SRF3216A-222Y common mode choke is ideal for applications where attenuation of noise signals and harmonics is needed. It can be used as a low frequency noise reduction device. It is also used in communication circuits and in power lines to reduce electromagnetic interference. It can be used as the last stage of noise filtering as it provides high isolation and low pass-band attenuation.In addition, the SRF3216A-222Y can be used as a wide-band choke in power lines and communication lines. The choke makes use of its internal capacitance to form an LC filter. The LC filter provides high isolation and wideband, low pass-band attenuation characteristics. The choke reduces both differential-mode currents and common-mode currents. This reduces interference to other circuit components and reduces the adverse effects of switching noise on the surrounding environment.The SRF3216A-222Y can also be used in industrial applications. It is well-suited for applications that require low-noise operation such as communications systems, automotive and medical devices. It is also suited for EMC applications and power supply circuitry to reduce EMI. Additionally, it can be used to filter out high frequency signals in switching power supplies.In conclusion, the SRF3216A-222Y common mode choke is a versatile and robust component for noise reduction applications. It features low series resistance, a high isolation, wide-band, low pass-band attenuation characteristics, ceramic housing, and its maximum temperature is 125°C to provide reliable operation. It is suitable for use in communication and industrial systems, automotive and medical equipment, as a wide-band choke in power lines, or as the last stage of noise filtering in power lines and communication lines.
