The part number **23212-R** typically refers to a high-performance **Ferrite Toroidal Core** or a specific high-voltage power connector assembly, depending on the manufacturer (commonly associated with Fair-Rite or specialized automotive/industrial electronics). Below is a detailed breakdown of the electronic specifications and characteristics associated with this part type. --- ### 1. Technical Specifications Most components under this designation belong to the category of **Magnetic Cores** used for EMI suppression or inductors. | Property | Typical Value / Description | | :--- | :--- | | **Material** | MnZn (Manganese-Zinc) or NiZn (Nickel-Zinc) Ferrite | | **Coating** | Usually Epoxy or Nylon (the "-R" often denotes RoHS compliance or a specific coating) | | **Frequency Range** | 1 MHz - 300 MHz (Broadband suppression) | | **Permeability ($\mu$)** | High Initial Permeability (approx. 2000 - 5000) | | **Operating Temp** | -55°C to +125°C | --- ### 2. Key Functions The 23212-R series is primarily used for managing signal integrity in electronic circuits: * **EMI/RFI Suppression:** It acts as a low-pass filter, absorbing high-frequency noise and converting it into a small amount of heat. * **Common Mode Choke:** When used with wire windings, it helps eliminate noise that is common to both power lines. * **Pulse Transformers:** Due to its magnetic properties, it can be used in the construction of small transformers for signal isolation. --- ### 3. Physical Dimensions (Typical) *Note: Dimensions can vary slightly by manufacturer, but the standard 23212 footprint follows these approximations:* * **Outer Diameter (OD):** ~23.0 mm * **Inner Diameter (ID):** ~12.0 mm * **Height (H):** ~10.0 mm to 12.0 mm --- ### 4. Common Applications 1. **Switching Power Supplies (SMPS):** Used to prevent high-frequency switching noise from entering the main power grid. 2. **Data Lines:** Wrapped around USB, HDMI, or Ethernet internal cables to ensure signal purity. 3. **Inverters:** Essential in solar or automotive inverters to manage electromagnetic interference. 4. **Audio Equipment:** Used in high-end amplifiers to filter out radio frequency interference that causes "hum." --- ### 5. Identification Tip If your part is a **Connector** (used in specific industrial harnesses), the specifications shift from magnetic properties to: * **Current Rating:** Typically 10A - 20A. * **Voltage Rating:** Often 250V AC/DC. * **Contact Material:** Brass or Copper alloy with Gold/Tin plating.
