Frequently Asked Questions
Q: What is the typical application for the NFM21PC475B1A3D feed-through capacitor?
A: This component is used for high-frequency noise suppression in power supply lines, particularly in DC-DC converters, due to its low 5mOhm DCR and 6A current rating.
Q: Can this 4.7 µF feed-through capacitor replace a standard MLCC?
A: No. Unlike standard MLCCs, this three-terminal feed-through capacitor provides superior high-frequency attenuation with a through-line structure for EMI filtering.
Q: What is the maximum DC voltage this component can handle?
A: The rated voltage is 10V, meaning it is suitable for 5V or 3.3V power rails but should not be used in 12V circuits.
Q: Is the NFM21PC475B1A3D suitable for high-current designs?
A: Yes. With a 6A rated current and an ultra-low DCR of 5mOhm, it minimizes power loss and heat generation in power line filtering.
Q: What is the operating temperature range of this feed-through capacitor?
A: It operates from -40°C to +85°C, making it suitable for consumer electronics and industrial control applications.
Q: What is the physical size and mounting style of this component?
A: It uses a surface-mount 0805 (2012 metric) package with 3 PC pads, measuring 2.00mm x 1.25mm with a max height of 0.95mm.
Q: Does this part support cut tape (CT) packaging for prototypes?
A: Yes. It is available in both Cut Tape (CT) for small quantities and Tape & Reel (TR) for automated assembly.
