This geometry creates a highly effective low-pass filter that diverts high-frequency EMI noise directly to ground, preventing it from propagating through your circuit or escaping as radiated emissions. They are a go-to solution for engineers designing to meet EMC compliance standards.\u003c\/p\u003e\n\n\u003cp\u003eFor more information on electromagnetic compatibility (EMC) standards and best practices, visit the NIST Electromagnetic Compatibility resources.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eQ: What capacitance values are included, and how do I choose the right one?\u003c\/h4\u003e\n\u003cp\u003eA: This listing offers 10 pF, 100 pF, 1000 pF (102), 2200 pF (223), 3300 pF, 4700 pF, 1 µF, and 2 µF options. For high-frequency EMI suppression (RF, switching noise), smaller values like 100 pF–1000 pF are typically most effective. For low-frequency or mains-line filtering, larger values such as 1 µF–2 µF are preferred. Select based on the frequency range of the interference you need to attenuate.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What does the M4 thread designation mean for mounting?\u003c\/h4\u003e\n\u003cp\u003eA: M4 refers to the Metric standard thread with a 4 mm nominal diameter. This is a widely used panel-mount thread size — simply drill a standard M4 hole in your chassis, enclosure, or PCB standoff, and secure the capacitor with the included or standard M4 nut for a solid, grounded connection.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Are these feed-through capacitors suitable for both AC and DC circuits?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. With a 100V rating, these capacitors can be used in both DC applications and low-voltage AC circuits, provided the peak voltage does not exceed the rated value. Always verify that your application's operating voltage, including transient spikes, remains within the 100V rating for reliable long-term performance.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between a 10-piece and 20-piece pack?\u003c\/h4\u003e\n\u003cp\u003eA: Both packs contain the same high-quality feed-through capacitors. The 10-piece option is ideal for prototyping or small repairs, while the 20-piece pack offers greater value for production runs, lab stock, or projects requiring redundancy.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What capacitance values are included, and how do I choose the right one?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This listing offers 10 pF, 100 pF, 1000 pF (102), 2200 pF (223), 3300 pF, 4700 pF, 1 µF, and 2 µF options.
