Frequently Asked Questions
1. What is a 0.4mm pitch B-to-B battery connector used for?
This connector is specifically designed for board-to-board battery connections in ultra-thin consumer electronics such as smartphones, tablets, smart wearables, power banks, and portable medical devices. It provides a reliable high-current power path between the battery and the mainboard in an extremely compact form factor.
2. What pin counts are available?
The GY046P series is available in 10P, 14P, 16P, 20P, 24P, 30P, 40P, and 50P configurations. The 24P version measures only 4.40mm wide. Each product includes both the male header (plug) and female receptacle (socket) as a mating pair.
3. How thin is the mated profile?
The mated height is just 0.98mm, making it suitable for the thinnest smartphone and wearable designs. Combined with the 0.40mm pitch, this connector saves significant PCB real estate compared to standard BTB connectors.
4. What current can this connector handle?
This connector is specifically engineered for high-current battery power transmission with a rated voltage of 50V AC/DC and a contact resistance of ≤100mΩ max. The full gold plating on nickel underplate ensures minimal power loss and stable current delivery under load.
5. What is the operating temperature range?
The connector operates reliably from -35°C to +105°C, with the insulator made of LCP (Liquid Crystal Polymer) rated UL 94V-0. This wide range covers consumer device charging, discharging, and extreme ambient conditions.
6. What plating is used on the terminals?
Terminals are made of high-performance copper alloy with a minimum 50µ” nickel underplate followed by full gold plating. This dual-layer plating process significantly reduces contact resistance and provides superior corrosion and oxidation resistance for long-term reliability.
7. Is this connector suitable for SMT assembly?
Yes. The connector is designed for standard SMT (Surface Mount Technology) assembly processes. The dual-row terminal layout ensures stable coplanarity for reliable soldering, and the LCP housing withstands reflow soldering temperatures without deformation.
8. What are the insulation and dielectric ratings?
Insulation resistance is ≥50 MΩ minimum, and the connector can withstand 500V AC for one minute without breakdown, ensuring safe operation in battery management circuits where voltage isolation is critical.
9. Do you provide technical drawings and datasheets?
Yes. Request PDF technical drawings, 3D models, and detailed specifications using the form above (click “Download Specifications & Request a Quote”). Our engineering team can also assist with footprint recommendations and application design support.
