FF TEK Co.,Limited is a one-stop service from PCB board manufacturing, BOM electronic components manufacturing&procurement and PCB Assembly company, Founded in 2011, we have more than 10 years of manufacturing and sales experience in related industries. Our company is committed to reform and innovation to adapt to the changing market demand.
Our company's main business is the production and procurement of electronic components (including the production of various switches and connectors, as well as the procurement of semiconductors, etc.), PCB and PCBA. Our products are widely used in consumer electronics, automotive industry, industrial control, medical and communication fields.
The power relay has different electrical contact characteristics and failure phenomena under different load types and under different load conditions. The types of loads include capacitive loads, motor loads, inductive loads, DC loads, low-level loads and dry circuits. Different load types have their own relatively common failure modes. The magnitude of the load is closely related to the failure form and failure mechanism. Contact bonding is easy to occur under loads above medium power.
Micro power relay: when the contact open circuit voltage is DC 28V, the contact rated load current (resistance) is 0.1A; 0.2A relay;
Weak power relay: When the contact open circuit voltage is DC 28V, the contact rated load current (resistive) is 0.5A; 1A relay;
Medium power relay: When the contact open circuit voltage is DC 28V, the contact rated load current (resistive) is 2A; 5A relay;
Large power relay: When the contact open circuit voltage is DC 28V, the contact rated load current (resistive) is 10A; 15A; 20A; 25A; 40A... Relay.
Power relay can expand the control range: it can switch, break, and connect multiple circuits at the same time according to different forms of contact groups.
The power relay has an amplifying effect: with a very small amount of control, a circuit with a large power can be controlled.
Automatic, remote control, monitoring: other electrical appliances form a program control circuit together to realize automatic operation.
Procured from the company for more than 5 years, from the initial one or two products to the current BOM procurement, the product quality is stable, the delivery is timely, especially the after-sales service is very professional, I hope there will be more projects for cooperation in the future.
This is exactly what I was looking for. No, I mean EXACTLY. We are a company that designs lighting equipment,We have cooperated with FF tech for many years. Most of our electronic materials are purchased from here. We cooperate very well from proofing, trial production to mass production.
Our company has ordered ICs, connectors, switches and other electronic components from your company since 2017. After years of cooperation and consideration, the products you sell fully meet our requirements and our company's consideration of product quality.
We have long-term purchase of PCB boards from this company, perfect assortment for various projects, and a great value for the money. The soldered holes and pads are perfect, markings clear, and they’re all trimmed perfectly with no rough or uneven edges.
Our company was established in 2011, we have more than 10 years of manufacturing and sales experience in related industries.
The main business of our company is the production and procurement of electronic components (including the production of various switches and connectors, as well as semiconductors, etc.), PCB and PCBA procurement.
Our various products are exported to South Korea, Japan, Europe and the United States and other countries and regions, with strong strength to meet the supply needs of various types of customers.
