1812TRX Series

Compact SMT Ethernet Isolation Transformer

Coilcraft’s 1812TRX Ethernet isolation transformer features a fully automated construction, not only reducing cost but also increasing reliability. Its compact surface mount package measures just 4.5 x 3.2 x 3.1 mm, significantly smaller than traditional hand wound toroidal transformers. The 1812TRX is AEC-Q200 qualified, making it an ideal choice for automotive and other harsh-environment applications. It also meets Gigabit Ethernet 10/100/1000BASE-T1 and Power over Ethernet standards per IEEE 802.3, ensuring seamless integration into a variety of network environments.

Complies with IEEE 802.3 Standards
Chip-style in a compact SMT package: 4.7 x 3.1 x 3.1 mm
Fully automated for cost reduction and reliability
AEC-Q200 qualified

메모

When ordering, please specify packaging code: e.g. 1812TRX-S254RC
Inductance is per winding, measured at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4263B LCR meter and a Coilcraft CCF 1113 fixture.
1500 Vrms, one minute isolation (hipot) between primary to secondary.

IDC max per the center tap is the current required to increase the part temperature 15°C from ambient 25°C.
