FAQ LAN Transformer: WHSH16037D0
Q
Why must the 2500 VAC, 1 mA, 5 s specification of WHSH16037D0 not be written as '2500 V operating withstand voltage'?
A
It is a dielectric withstand test between windings: apply 2500 VAC with a 1 mA leakage-current limit for 5 s to verify short-duration insulation integrity. It is not a continuous operating voltage. System safety must be evaluated separately against the actual working voltage, insulation class, creepage distance, clearance, and applicable standards.
Q
Which dimensions are critical when creating the SMD land pattern and mechanical model for WHSH16037D0?
A
The body is approximately 12.80 ± 0.50 mm × 6.90 ± 0.50 mm and approximately 5.65 ± 0.50 mm high. Pin pitch is 1.27 mm, the longitudinal pad span is 8.89 mm, and the center-to-center distance between pad rows is 10.50 mm. Before placement, also assess how the 0.76 mm pad width, coplanarity, and 0-8° lead angle affect solder-paste volume and solder wetting.
Q
Which room-temperature specifications still require system-level review when WHSH16037D0 is used from -40 to +85 °C?
A
Both operating and storage ranges are -40 to +85 °C, but the electrical specifications use 25 ± 5 °C as their reference. Verify link operation, bit-error performance, and EMC at the temperature endpoints. The minimum 350 μH open-circuit inductance is measured at 100 kHz, 0.1 V, and 8 mA bias; the 8 mA value is only a test condition and is not PoE current capability.
Q
What Certifications Does VOOHU Hold?
A

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.

Q
