FAQ LAN Transformer: WHSH16012P4

What system-level checks are still required when using the 720 mA capability of WHSH16012P4 in an IEEE 802.3at project?

›

The 720 mA rating allows the component to be evaluated for an IEEE 802.3at design, but it does not replace a complete system calculation. Confirm the power-pin and center-tap connections, PSE/PD role, cable and connector ratings, PCB copper temperature rise, and PD power at the worst-case input voltage, then perform full-load temperature-rise and link bit-error testing.

Why must the crosstalk limit of WHSH16012P4 not be replaced with the 30 dB value used by other 16PIN 10/100BASE-T models?

›

WHSH16012P4 specifies a crosstalk-attenuation magnitude of at least 15 dB from 1 to 100 MHz, while its common-mode rejection magnitude is at least 30 dB over the same range. Component acceptance must use the limits of WHSH16012P4 itself rather than values from a model with a similar outline. Board-level link and EMC targets still require system testing.

Which temperature and time limits should be included in the reflow process card for WHSH16012P4?

›

Include these limits: heating rate no greater than 3 °C/s; cooling rate no greater than 6 °C/s; 60-180 s at 150-200 °C; 60-150 s above 217 °C; peak temperature 250 °C (+0/-3 °C); 20-40 s within 5 °C of the actual peak; and no more than 8 min from 25 °C to peak. Verify the actual profile by measuring the populated board.

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.
