Mylar Capacitor: Its Unique Performance Explained – PCB COPY
Mylar capacitors have a relatively low temperature coefficient, typically ranging from -2% to +2% over a temperature range of -55°C to +125°C. This low temperature coefficient makes Mylar capacitors suitable for applications that require stable capacitance values across a wide temperature range, such as in automotive and industrial electronics.
Motor start capacitor affecting motor temperature
Hi, I had a motor start capacitor (450V, 7uF) die in a tumble drier. I had a 6uF, 400V one handy, so I used that while I waited for the replacement part. It seemed to be fine, except the drier seemed to be stopping early. After switching back to the spec''d part it was fine again. For my...

6 FAQs about [400V capacitor temperature exceeds]
What is the temperature coefficient of a capacitor?
The Temperature Coefficient of a capacitor is the maximum change in its capacitance over a specified temperature range. The temperature coefficient of a capacitor is generally expressed linearly as parts per million per degree centigrade (PPM/ o C), or as a percent change over a particular range of temperatures.
What happens if a capacitor exceeds its maximum voltage?
Using a capacitor beyond its maximum voltage can lead to damage, reduced performance, or even failure of the capacitor, compromising the entire circuit.
Can aluminum electrolytic capacitors exceed rated voltage?
ll not exceed the rated voltage.In the case where more than 2 aluminum electrolytic capacitors are used in series, please make sure that applied voltage will be lower than rated voltage and the voltage be will applied to each capacitor equally using a balancing resistor
What is a normal working temperature for a capacitor?
The normal working range for most capacitors is -30 o C to +125 o C with nominal voltage ratings given for a Working Temperature of no more than +70 o C especially for the plastic capacitor types.
How does temperature affect the reliability of a capacitor?
As the temperature rises, the working voltage of the capacitor can decrease, which may affect its overall reliability. If the capacitor operates in a high-temperature environment, it’s important to choose one with a sufficient voltage rating to accommodate the temperature variations.
What are the requirements of a capacitor?
all be within the specification.The capacitor shall not be used in an ambient temperature which exceeds the operating temperatur specified in the specification.Do not apply excessive current which exce the allowable ripple current.Appropriate capacitors which comply with the life requirement of the products should be sel
