Feed Through Capacitors: PSM4-152M-15B Application Field and Working PrincipleFeed through capacitors, also known as panel-mount, plug-in or panel-shape disk capacitors, are special-shaped capacitors that are mounted flush and insulated with the panel cutout. Generally, feed through capacitors are employed to filter electro-magnetic signals or radio signals. In this article, we will be examining the PSM4-152M-15B feed through capacitor, its application field and working principle.The PSM4-152M-15B feed through capacitor is typically used in automotive electronics. It has an ultra-low ESL of 0.55pF and a high current rating of 530mA. It is capable of achieving high-speed switching, enabling faster, more precise electrical control. Additionally, its fast frequency response limits acoustic feedback and improves system performance. Its shielding technology also helps reduce the influence of external interference on the circuit.The working principle of the PSM4-152M-15B feed through capacitor is simple. It acts as a non-linear resistor, allowing the current to flow through the capacitor when the voltage is below a certain threshold. When the voltage exceeds the threshold, the capacitor acts as a short, preventing current from flowing. This highly efficient switching is what makes it a popular choice for automotive applications.In terms of installation, the PSM4-152M-15B feed through capacitor is designed to be mounted directly onto the panel cutout. When installing the capacitor, careful consideration should be taken to ensure that the current rating is not exceeded. Additionally, the capacitor must be fully insulated from the panel cutout to reduce the risk of electric shock.The PSM4-152M-15B feed through capacitor is a popular choice for automotive electronics due to its high current rating and ultra-low ESL. It is capable of achieving high-speed switching and its shielding technology helps reduce the influence of external interference. Additionally, when installing the capacitor, it is important to consider its current rating and get proper insulation of its panel cutout to ensure safety.
