The 47K275V X2 Datasheet holds the key to understanding a crucial component used for electromagnetic interference (EMI) suppression in various electronic devices. This document provides detailed specifications, characteristics, and performance data for a specific type of capacitor, helping engineers and designers ensure their products meet safety standards and operate reliably in noisy electrical environments.
Decoding the 47K275V X2 Capacitor
The “47K275V X2” designation reveals several key aspects of this capacitor. “47” typically represents the capacitance value, often expressed as 0.47 microfarads (µF). “K” denotes the capacitance tolerance, typically ±10%. “275V” signifies the rated voltage, indicating the maximum AC voltage the capacitor can safely withstand. Finally, “X2” categorizes the capacitor’s safety rating, specifically for across-the-line applications. These capacitors are designed to be connected between the phase and neutral conductors in AC power circuits. Their primary purpose is to suppress unwanted electrical noise and prevent it from propagating through the power line and affecting other devices.
X2 capacitors are a specific type of safety capacitor, meaning they are designed to fail safely in the event of overvoltage or other stress conditions. Unlike standard capacitors, which might short-circuit and create a fire hazard, X2 capacitors are designed to fail open, preventing dangerous short circuits. Key characteristics found in the 47K275V X2 Datasheet often include:
- Capacitance value and tolerance
- Rated voltage (AC)
- Operating temperature range
- Dissipation factor
- Insulation resistance
- Safety certifications (e.g., ENEC, UL, CSA)
X2 capacitors, including the 47K275V X2, are widely used in a variety of applications, including:
- Power supplies
- Consumer electronics (e.g., televisions, washing machines)
- Industrial equipment
- Lighting ballasts
The Datasheet provides essential information for selecting the appropriate capacitor for a specific application, ensuring optimal performance and safety. For example, consider the following simplified table showing voltage vs application:
