# FilterElectricalRC

>  Basic Electrical RC filter 

## Parameters

<ParamField path="cutoff_frequency" type="hertz" />

<ParamField path="order" type="dimensionless" />

<ParamField path="response" type="dimensionless" />

## Interfaces

<ParamField path="in_" type="ElectricSignal" />

<ParamField path="out" type="ElectricSignal" />

## Global Attributes

These attributes are available to all modules and interfaces in a design.

<ParamField path="lcsc_id" type="str">
  Assign the LCSC ID of the module.

  If set, this will tell the picker to select that part from LCSC for this block.
</ParamField>

<ParamField path="manufacturer" type="str">
  This module's manufacturer name, as a string.

  Only exact matches on the manufacturer's name will be found by the picker.
  It's recommended to fill this information based on what `ato create component`
  provides.
</ParamField>

<ParamField path="mpn" type="str">
  This module's manufacturer part number, as a string.

  For the picker to select the correct part from the manufacturer,
  this must be set.
</ParamField>

<ParamField path="package" type="str">
  The package of the module.

  This drives which components can be selected, and what footprint is used.

  Must exactly match a known package name.
</ParamField>

<ParamField path="exclude_from_bom" type="bool" />

<ParamField path="override_net_name" type="str">
  When set on an interface, this will override the net name of the interface.

  This is useful for renaming nets which are automatically generated.
</ParamField>

<ParamField path="required" type="bool">
  Only for ModuleInterfaces.
  If set to `True`, require that interface is connected to something outside
  of the module it's defined in.
</ParamField>

<RequestExample>
  ```ato Basic Usage theme={null}
  import FilterElectricalRC, ElectricSignal, ElectricPower

  # Create low-pass RC filter
  rc_filter = new FilterElectricalRC
  rc_filter.cutoff_frequency = 1kHz +/- 10%

  # Connect power reference
  power_supply = new ElectricPower
  assert power_supply.voltage within 5V +/- 5%
  rc_filter.in_.reference ~ power_supply
  rc_filter.out.reference ~ power_supply

  # Connect input and output signals
  input_signal = new ElectricSignal
  output_signal = new ElectricSignal
  input_signal ~ rc_filter.in_
  rc_filter.out ~ output_signal

  # Alternative: use hardcoded values for faster solving
  rc_filter_fixed = FilterElectricalRC.hardcoded_rc(1kohm +/- 5%, 100nF +/- 10%)
  ```
