The above prices are retail prices, please contact customer service for bulk quantities! Due to the wide variety of electronic components we operate, we cannot upload them one by one. If you cannot find the required component in my store. For connectors and other auxiliary accessories, just send the physical list (BOM) to customer service. You can solve the problem in one stop, covering chips, diodes, capacitors, resistors, connectors and switches. It saves labor cost and time to a large extent.
