The WEET CL21 MER Metallized Polyester Film Capacitor is one of the common models in the MER series, and its cost is affected by multiple factors such as raw materials, production processes, and performance parameters.
1. Core Raw Material Costs (Accounting for the Highest Proportion, Directly Determining the Basic Cost)
Metallized polyester film.
Lead materials.
Packaging materials.
2. Compliance and Certification Costs (High-Standard Certifications Increase Costs)
For consumer products: They only need to comply with China's GB standards and the EU's CE standards, resulting in relatively low certification costs.
For automotive electronics: Compliance with AEC-Q200 certification is required, which involves high costs.
Please refer to this image and its corresponding table:
| Capacitance uF | Voltage V | Pitch size mm | L*T*H mm |
| 2.2uF | 250V | 27 | 29*9*15.5 |

Have you ever encountered a failure of a Safety Ceramic Capacitor X2 Type?
Let's Explore the Failure Modes of X2 Capacitors Together: Symptoms and Failure Prevention Recommendations.
| Failure Mode | Core Mechanism | Key Symptoms |
| Open Circuit | Internal conductor/electrode breakage | No current flow; Equipment malfunction |
| Short Circuit | Dielectric breakdown | Excessive inrush current; May trigger circuit breaker tripping; in severe cases, the capacitor case may bulge, smoke, or even catch fire. |
| Parameter Drift | Film dielectric aging | Significant decrease in capacitor capacitance |
Failure Prevention Recommendations:
Component Selection Matching: Strictly select X2 capacitor application with appropriate specifications based on circuit operating conditions. Ensure that the rated voltage, rated temperature, and ripple current all meet the design requirements.
Environmental Control: Avoid prolonged exposure of capacitors to high-temperature environments, high-humidity environments or corrosive environments.
Electrical Protection: Add surge suppression components (such as varistors) and overload protection components to the circuit to reduce the impact of voltage spikes and overcurrents on Capacitors for Interference Suppression X2.
Regular Maintenance: For Class X2 Safety Capacitors in critical equipment, it is recommended to conduct electrical parameter testing once every 1–2 years to identify potential failure risks in advance.
