Frequently Asked Questions (FAQs)
What should I look for when choosing a Knowles hi-rel capacitor supplier?
Look for suppliers with strong technical expertise, quality certifications (like ISO9001 and AS9100), proven track records with hi-rel components, and good customer support. It’s also important that they can supply authentic products and offer customization or technical assistance if needed.
How can I verify the authenticity of Knowles hi-rel capacitors from a supplier?
Always choose authorized distributors or direct manufacturers listed on Knowles’ official website. Request certificates of conformity, traceability documents, and ensure their packaging and labeling match Knowles’ standards to guarantee authenticity.
What quality standards should a reliable supplier have?
A reliable supplier should be certified with relevant quality standards such as ISO9001 and, for aerospace or defense applications, AS9100. These certifications assure quality management and compliance with industry requirements for hi-rel components.
Are there minimum order quantities (MOQs) when purchasing from manufacturers?
Yes, many manufacturers have MOQs which can vary depending on the capacitor type or custom requirements. It’s best to clarify MOQ policies with the supplier early in your discussions to ensure they align with your project needs.
How do I compare prices and lead times between different Knowles capacitor suppliers?
Request detailed quotes from several authorized suppliers, including pricing, lead times, shipping costs, and payment terms. Also, consider their reputation for meeting delivery schedules and their willingness to communicate updates throughout the ordering process.
