10/100BASE-TX VoIP Magnetics Module – VP8019M HF

Overview:

The VP8019M HF is a high-performance 10/100BASE-TX magnetics module specifically designed for Voice over IP (VoIP) applications, including IP phones and Ethernet switches. Engineered to meet IEEE 802.3af and ANSI X3.263 standards, this module ensures reliable signal integrity, efficient power handling, and seamless network performance.

Key Features:

✅ IEEE 802.3af / ANSI X3.263 compliant for PoE (Power over Ethernet) support.

✅ Supports up to 350 mA current for power-demanding VoIP devices.

✅ Optimized for IP phone and Ethernet switch integration.

✅ Compact footprint for space-constrained PCB designs.

✅ Optional Auto MDIX support, enabling automatic detection of straight-through or crossover cables.

✅ Operating Temperature: 0°C to +70°C

✅ Storage Temperature: -10°C to +85°C
