This Product Selection Guide contains information to help select products in the Power Line Filter Modules category on DigiKey.com
Power line filter modules are modularized passive component assemblies that are used to inhibit current flow through power supply conductors at frequencies outside that which is nominal for the intended supply. Commonly used in conjunction with AC utility power sources, they are used both to mitigate interference caused by outside sources as well as suppress potential interference which might be caused by a connected device.
SelectionCharacteristics
Filter Type: Defines what kind of power line the part is designed to filter.
Configuration: Defines if the part is a one, two, or three stage filter.
Voltage - Rated DC: Indicates the maximum DC voltage rating to which a device will meet its given specifications. Exceeding this voltage rating may damage the device and other system components.
Voltage - Rated AC: Indicates the maximum AC voltage rating to which a device will meet its given specifications. Exceeding this voltage rating may damage the device and other system components.
Voltage - Rated AC (Phase to Ground/Neutral): The rated maximum operating voltage (AC RMS) of a device, measured between any phase conductor and the ground or neutral conductor.
Voltage - Rated AC (Phase to Phase): The rated maximum operating voltage (AC RMS) of a device, measured between any two phase conductors.
Current: Typically this represents the maximum current to which a device will meet its given specifications. Exceeding this current may damage the device and/or other system components.
Frequency - Operating: Indicates the nominal operating frequency of the power sources with which a device is intended to be used.
Applications: Application is the type of equipment or environment the device will be used in, they are tested and typically rated by a third party to ensure certain minimum standards for the application they are intended for.
Approval Agency: An indication that the product meets the minimum safety standards of an approving agency. These agencies are either government entities or private third-party labs that protect consumer safety.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Mounting Type: Indicates how the device is attached.
Termination Style: Selection of termination style used to connect the device to a system, such as pin, quick connect, or wire leads.
Inductance: Indicates nominal values of the inductor(s) incorporated in a filter module.
