FAQ LAN Transformer: WHD12501TG

What is the main selection difference between WHD12501TG and WHD12501G?

›

The main difference is temperature grade. WHD12501TG is rated for both operation and storage from -40 to +85 °C, while WHD12501G operates from 0 to +70 °C. Their mechanical dimensions are similar, but substitution still requires comparison of the pin diagram, document revision, and prototype results. A temperature-related suffix does not replace a complete substitution review.

Can link conclusions measured at 25 °C be used directly when WHD12501TG operates at -40 °C or +85 °C?

›

No. The electrical specifications are stated with 25 °C as the reference, while -40 to +85 °C defines the operating environment. Engineering validation should cover link establishment, bit-error performance, and EMC at cold start, high-temperature steady state, and after temperature cycling. Use the actual local component temperature for internal hot spots rather than only the chamber setpoint.

How should the 1500 VAC dielectric withstand condition and 8 mA biased-inductance condition of WHD12501TG be kept from being misinterpreted?

›

The 1500 VAC, 1 mA, 60 s value is a dielectric withstand test between windings, not a continuous operating voltage. The 8 mA value is the DC-bias test point for the 350 μH minimum open-circuit inductance, not a port power-current rating. The two parameters address isolation and magnetizing characteristics separately; neither establishes PoE power or an end-product safety classification.

What Certifications Does VOOHU Hold?

›

VOOHU is certified to ISO 9001:2015 and ISO 14001:2015 standards. Our products comply with RoHS, REACH, and CE requirements, ensuring high quality, environmental compliance, and reliable performance for global markets.
