The QPI-21 is derived from the industry proven Picor QPI-6 QuietPower® active EMI filter but enhances filter attenuation and versatility. The QPI-21 active EMI filter attenuates conducted common-mode (CM) noise to 45dB and differential-mode (DM) noise to 80dB over the CISPR22 frequency range of 150 kHz to 30 MHz. In addition, the QPI-21 has increased filtering capability to different DC-DC converter grounding schemes increasing its usage with various industry dc-dc converters. In addition, the QPI-21 has package pad connections allowing for the option of additional X capacitance to be used. The QPI-21 is packaged in the standard Picor LGA SiP with a ~1 inch 2 area.
