• High-Frequency Operation: Switching frequency optimized between 200 kHz - 700 kHz, enabling compact magnetics and high-density designs -- a reliable high-frequency transformer choice for modern power systems.
• Low-Profile Design: Ultra-low profile with a 10.5 mm (adjustable) height for thin SMD assemblies and tight-board designs.
• High Isolation & Temperature Range: Isolation rating 1500 VDC and wide operating/storage temperature -40 °C to +125°C for robust field performance.
• Compliance & Materials: Lead-free, RoHS compliant; termination finished with Sn-0.7Cu. Selected variants cite IEC60950 compliance where applicable.
• Applications Versatility: Designed specifically as a POE transformer for PoE power delivery, it is ideal for surveillance cameras, IP phones, wireless access points, and other PoE-powered IoT/edge devices.

• Topology: Forward converter (supports half/full bridge and active clamp topologies).
• Switching Frequency: 200 kHz - 700 kHz (optimized).
• Isolation Voltage: 1500 VDC (typical hi-pot test conditions shown in datasheet).
• Operating Temperature: -40°C to +125°C (including self temperature rise).
• Profile: Low-profile, 10.5 mm max (adjustable in some package variants).

• Power: 50W-150W class depending on model; commonly used 120W/150W configurations for PoE power stages.
• Typical Turns / Inductance / DCR: Multiple part-specific windings and OCL/LK values are provided in the product datasheet for accurate design matching (see datasheet tables for part numbers POE-TP65-116 ~ POE-TP65-130). Designers should choose the part number matching target turns ratio and leakage inductance for their converter topology.

• PoE Power Systems: Centralized PoE power supplies, midspans, and PoE injectors.
• Surveillance: Powering IP cameras and PTZ modules where low profile and isolation are required.
• Enterprise Networking: Wireless APs and VoIP/IP phones requiring reliable isolated power.
• IoT & Edge Devices: Low-profile power modules for compact sensors and gateway devices.

• Optimized for modern PoE topologies -- compact, high-frequency magnetics reduce PCB area and improve thermal characteristics.
• Robust isolation and wide temperature range ensure field reliability in industrial and commercial deployments.
• Multiple part variants and winding options allow designers to match turns ratio, leakage inductance and DCR to forward-converter designs for maximum performance.

For part selection, refer to datasheet tables (POE-TP65 series) for exact turns, OCL, LK, DCR and hi-pot values per part number. Example series items and mechanical footprints are shown in the datasheet to support PCB layout and pad design.

When integrating into forward-converter or active-clamp circuits, confirm leakage inductance and turns ratio requirements to meet transient and regulation targets.
