Q1: What is the difference between 10/100 Base-TX and 1000 Base-T transformers?
A1: The main difference lies in the transmission rate and the number of wire pairs used. 10/100 Base-TX transformers support speeds up to 100 Mbps and typically use two pairs of Cat5 cables (one for TX, one for RX). 1000 Base-T (Gigabit) transformers support up to 1000 Mbps (1 Gbps) and require all four pairs of Cat5e or Cat6 cables to achieve full-duplex transmission on all four pairs simultaneously. If you need higher bandwidth for applications like HD video streaming or large data transfers, we recommend the 1000 Base-T series.
Q2: Can these network transformers support PoE (Power over Ethernet) applications?
A2: Yes, we offer 10/100 Base-TX transformers that are PoE (Power over Ethernet) ready. These models are designed with a center tap structure that can safely carry the DC power required for PoE applications (such as IP cameras, VoIP phones, and wireless access points) while maintaining signal integrity. Please check the product datasheet for the isolation voltage rating (typically 1500Vrms) to ensure it meets your PoE requirements.
Q3: What is the difference between SMD and DIP packaging? Which one should I choose?
A3: The choice between SMD (Surface Mount Device) and DIP (Dual In-line Package) depends on your production process.
* SMD is designed for automated assembly lines with pick-and-place machines. It offers higher assembly efficiency and is ideal for high-volume, compact PCB designs.
* DIP is a through-hole package, which requires manual insertion or wave soldering. It is often used for prototyping, small-batch production, or applications requiring stronger mechanical bonding.
We offer both options, and our sales team can help you select the most suitable packaging based on your production scale and PCB layout.
Q4: Do you provide OEM/ODM services for custom network transformers?
A4: Yes, we specialize in OEM/ODM services for network transformers. We can customize the following parameters based on your specific requirements: Turns Ratio, Open Circuit Inductance (OCL), Hi-Pot (Isolation Voltage), operating temperature range, pin layout, and even the marking on the component. We also offer free samples for testing before mass production. Please provide your detailed specifications or schematic, and our engineering team will get back to you within 24 hours.
Q5: What certifications do your network transformers have? Are they RoHS compliant?
A5: Our network transformers are manufactured in compliance with international standards. All our products are RoHS (Restriction of Hazardous Substances) compliant and REACH compliant, ensuring they are environmentally friendly and safe for use in consumer electronics. Additionally, we can provide CE and FCC certification documents upon request. For specific projects requiring UL certification, we offer UL-listed models as well. Please let us know your target market and we can provide the appropriate compliance documentation.
