FAE Expert Insights
"The WTB-VH series is my go-to for power applications up to 15A. The large contacts and generous pitch provide excellent current capacity with low temperature rise. I've used these in power supplies and motor drives with excellent results. The ramp-style lock is easy to operate while providing secure retention. For best results, use AWG 16 wire for maximum current and ensure proper crimp quality. The connector is compatible with standard VH series headers from multiple manufacturers."

Frequently Asked Questions
What is the maximum current for WTB-VH-3P-CR?
The WTB-VH-3P-CR is rated for 15A per contact with all contacts powered simultaneously. This rating assumes AWG 16 wire and 30°C temperature rise. With all three contacts used for power (45A total), ensure adequate wire gauge and PCB copper area for heat dissipation. For continuous high-current operation, I recommend monitoring the connector temperature during validation testing. The connector can handle short-term overloads up to 20A per contact.
15A per contact with AWG 16. Use all contacts for power to maximize capacity.
What wire strip length is required for WTB-VH-3P-CR?
The recommended wire strip length for WTB-VH-3P-CR is 5.0-5.5mm. This length ensures proper contact between the crimp barrel and conductor while preventing exposed wire outside the insulation crimp. Use a quality wire stripper for consistent results. After crimping, verify that the conductor is visible through the inspection hole in the contact and that no strands are extending beyond the contact. The insulation should be captured by the insulation crimp without being crushed.
Strip 5.0-5.5mm of insulation. Verify through inspection hole after crimping.
