Audited Supplier An optocoupler, also known as an optoisolator or photocoupler, is an electronic component used to transmit electrical signals between two circuits while maintaining electrical isolation between them. It is often used to protect sensitive components from high-voltage or noisy environments, provide feedback, and ensure safety in various electronic applications.
The basic structure of an optocoupler consists of two main components: a light-emitting diode (LED) and a photodetector (such as a phototransistor or a photodiode) enclosed within a single package. These components are isolated from each other within the package by a transparent medium, typically an optically transparent material like plastic or glass.
When an electrical signal is applied to the LED input side, it emits light. The light then shines on the photodetector on the output side. The photodetector converts the incoming light signal into an electrical signal, which can be used to control or monitor the connected circuitry. Since there is no direct electrical connection between the input and output sides, optocouplers provide electrical isolation, protecting the input circuit from voltage spikes, noise, or potential differences that might exist on the output side.
1. What main products does we sell?
We sells full range of diodes and bridge rectifiers. Our advantages are most complete line of low voltage drop schottky diode, TVS, ESD, Mosfet, big Bridges, Transistor.
2.How long is a quote valid for?
All prices quoted are valid for 30 days from the date of quotation.
3.What is payment terms?
We prefer pay in advance via TT,western union and Paypal(for small amount only).
4. How long is the production lead time?
* Most items we have stock of complete items;
* Most items we have stock of chips, lead time 2~3 weeks;
* Partial items have not stock of chips, lead time 4~5 weeks.
* once order confirmed, we can check the exact lead time then
5. What is the freight charge when we buy diodes from JUXING?
As freight will varies according to the size and weight of the parts, different location of customers, we will quote ex-work, freight to collect and paid by customer courier account of DHL,UPS, FEDEX. Or we will check the shipping cost and add it to the total amount customer should pay.
6. May I have some samples for testing?
We offer free samples for our customers and they only need to pay the freight for samples.
7. How to assure worldwide customers receive components in good quality and condition?
1st, with advanced manufacturing technology ensure product reliability;
2nd Strict quality control system, ISO registered;
3rd, We will provide data sheet for all components, and we prefer customer trial test our parts, volumn orders to be placed after trial test pass;
4th, Factory would check product 100% before delivery, and international safety packaging will be applied to ensure parts arrive at customer in good condition.
