### Overview: BFC2336282 The **BFC2336282** is a specific part number belonging to the **Vishay BC Components** MKP336 2 series. It is a metallized polypropylene film capacitor designed primarily for **EMI suppression** and across-the-line applications. --- ### Technical Specifications The following table outlines the critical electrical and physical characteristics of this component: | Parameter | Specification | | :--- | :--- | | **Capacitance** | 2.2 nF (0.0022 µF) | | **Tolerance** | ±20% | | **Voltage Rating (AC)** | 310 VAC | | **Safety Class** | X2 | | **Dielectric Material** | Polypropylene Film (MKP) | | **Operating Temperature** | -55°C to +110°C | | **Termination Style** | Radial Leads | | **Lead Spacing** | 10.0 mm | --- ### Key Features and Functionality #### 1. X2 Safety Rating The "X2" designation is a safety classification. These capacitors are designed to be connected across the AC mains (line-to-neutral). They are engineered to fail safely (without causing a fire or electric shock) even if they are subjected to high voltage surges or spikes. #### 2. Self-Healing Properties Because it uses **metallized film** technology, the capacitor has "self-healing" properties. If a localized breakdown occurs in the dielectric, the thin metal layer evaporates around the point of failure, clearing the short circuit and allowing the capacitor to continue functioning. #### 3. Low Losses Polypropylene (MKP) is known for its very low dissipation factor and high insulation resistance, making it highly efficient for AC filtering. --- ### Common Applications The BFC2336282 is typically used in the following circuits: * **EMI/RFI Suppression:** Filtering out high-frequency noise from the power lines. * **Power Supplies:** Used in the input stage of Switched Mode Power Supplies (SMPS). * **Household Appliances:** Used in white goods to prevent electrical interference from affecting other devices. * **Across-the-line:** General purpose AC filtering. --- ### Dimensions and Mounting The part is housed in a flame-retardant plastic case (UL 94 V-0) with epoxy resin sealing. * **Pitch:** 10 mm (distance between pins). * **Mounting:** Through-hole (THT) on a Printed Circuit Board (PCB).
