LAN Transformers

Optimized Product Detail Page: LAN Transformers

Introduction
LAN Transformers (also called Pulse Transformers LAN) are critical magnetic components in Ethernet infrastructure. They enable galvanic isolation, impedance matching, and signal coupling while minimizing electromagnetic interference (EMI) in data transmission. These transformers are essential for PoE/PoE+ (Power over Ethernet) systems, delivering DC power alongside data signals through standard Cat.5/Cat.6 cables—eliminating separate power supplies for endpoints like IP cameras, wireless APs, and VoIP phones. Designed for reliability across industrial and commercial networks, our LAN Transformers ensure robust signal integrity in high-density environments.

Key Specifications

• Standards Compliance: 10/100/1000 BASE-T, IEEE 802.3ab (Gigabit Ethernet).

• Temperature Range: Operates at -40°C to +125°C, suitable for harsh industrial settings.

• Isolation & Noise Suppression: High common-mode rejection ratio (CMRR) and EMI shielding minimize signal distortion.

• Inductance: 350μH min (ensures stable PoE power delivery).

• PoE/PoE+ Support: Delivers 12.95W (PoE) to 30W (PoE+) power via data or spare pairs.

• Compact Design: Surface-mount (SMD) packages with 0.99mm/1.27mm pin spacing for high-density PCBs.

Applications
These Communication Transformers are engineered for:

• Network Hardware: Routers, switches, and servers requiring noise-resistant data coupling.

• PoE Devices: IP cameras, VoIP phones, and wireless APs where integrated power simplifies installations.

• Industrial IoT: Robotics, automated control systems, and broadcast video equipment demanding wide-temperature operation.

• Consumer Electronics: Set-top boxes, smart home hubs, and gaming consoles.

Design Advantages

1. Enhanced Power Efficiency
   Optimized core materials reduce DC resistance, minimizing heat generation in PoE applications. This complements designs using Power Inductors for voltage regulation.

2. Signal Integrity Protection
   Triple-shielded windings and low interwinding capacitance (<35pF) prevent crosstalk in multi-gigabit transmissions. Pair with RF Microwave Components or EMC Filter - EMI/RFI modules for full-spectrum noise suppression.

3. Space-Saving Integration
   Auto-manufactured SMD modules replace bulkier wire-wound variants, accelerating assembly and reducing labor costs. Ideal for compact devices alongside Sensors or RF Inductor arrays.

4. Future-Proof Scalability
   Supports up to 10G speeds and 100W PoE++ (IEEE 802.3bt), ensuring compatibility with next-gen networks.

Why Choose Our LAN Transformers?
As networks evolve toward smaller cables (e.g., 28AWG Cat.6) and higher densities, precision Transformers become indispensable. Our LAN Transformers deliver:

• Zero-latency data transfer for real-time applications (e.g., AR/autonomous systems).

• EMC Filter - EMI/RFI integration to meet FCC/CE directives.

• Drop-in compatibility with industry RJ45 connectors.
