Power line filters are devices used to reduce or eliminate electromagnetic interference (EMI) noise from power supply lines. EMI noise is generated by electronic circuits and devices and can cause disturbances in other components. To ensure safe and reliable operation of electronic devices, a properly designed power line filter must be installed. The SNA-01-000-D is a power line filter module manufactured by the Symmetrix Technology Corporation. It is designed to provide a reliable and efficient noise reduction solution for industrial and other power applications.

The SNA-01-000-D filter module is used in a variety of applications including industrial power systems, medical equipment, embedded systems, automotive electronics, and other power circuits. It employs a single PCB design with integrated EMC (electromagnetic compatibility) components and a low-pass filter (LPF) that provides effective attenuation of EMI over a wide frequency band. The LPF consists of a simple circuit with two capacitors, two inductors, and one resistor. Other components, such as common-mode chokes, spark gap protection, and bypass capacitors, may be added to the filter to improve its performance.

The SNA-01-000-D filter module provides both EMI filtering and EMC protection. The EMI filtering capability reduces unwanted conducted and radiated emissions coming from both the AC and DC sides of the filter. On the AC side, the filter reduces noise generated by switching power supplies and other high-frequency circuits, while on the DC side it reduces pulse width modulation (PWM) noise and ripple currents. The EMC protection component of the filter prevents dangerous voltage transients, ESD (electrostatic discharge) pulses, and other harmful disturbances from entering the power supply line.

The SNA-01-000-D filter module also has high power handling capabilities. It is rated for up to 25 Amps of continuous current at 3.6 KV and can handle short-term currents of up to 250 Amps. The module also features an operating temperature range of -40°C to +85°C and an optimal impedance matching of less than 1 ohm. This makes it ideal for use in harsh and hazardous environments, such as in oil rigs.

In addition to its robust design and high power handling capabilities, the SNA-01-000-D filter module also offers excellent EMC performance. The module features a total attenuation of more than 40dB from 10MHz to 1GHz, making it suitable for a wide range of applications. Furthermore, it has a high surge current capability of 2kA, enabling it to withstand powerful surges from lightning strikes. Finally, the module is UL approved and meets various safety and EMC standards, ensuring that it meets the highest levels of quality and reliability.

Overall, the SNA-01-000-D filter module is a reliable and efficient power line filter for various applications. With its robust design, high power handling capabilities, and excellent EMC performance, the module is a cost-effective and reliable solution for industrial and other power applications.
