BT15B Series

BT15B Series

To address the demand for high-capacity batteries and fast charging in smartphones, Kyomori-Ka has launched the BT15B series of battery connectors. This series features a footprint reduced by approximately 30% and a height lowered by 0.1 mm, effectively saving internal device space. Despite its compact design, it supports 15A high current and 100W USB PD fast charging, maintaining a temperature rise of less than 30°C at full 15A load. Additionally, the all-metal armored design at both ends significantly enhances structural integrity, effectively preventing damage caused by mating misalignment.

Product Features

Space-Saving Design With A 15A Rated Current
Power terminals are rated at 15A per pin and signal terminals at 0.3A per pin, offering high power delivery capability; a space-optimized design achieves extreme miniaturization.
The Product Has A Robust Structure.
Fully armored structure with metal shielding over the mating face and central section, preventing housing damage during misaligned mating.
High Terminal Contact Reliability
The design features 6-point contact for power terminals and 2-point contact for signal terminals; this multi-point structure ensures a stable connection.
Proper Mating Operation

The BM15B series consists of 15A power/signal hybrid board-to-FPC connectors featuring a 0.4mm pitch and a 0.7mm mating height. Metal guide leads accommodate generous mating

tolerances (±0.47mm in pitch and ±0.3mm in width) to ensure smooth mating, while a crisp tactile click prevents incomplete mating and enhances the user experience.

The Product Complies With RoHS Environmental Requirements.

Halogen-free. Chlorine or bromine levels in the connector do not exceed standard limits. * Defined according to the IEC 61249-2-21

standard as: Br ≤ 900 ppm, Cl ≤ 900 ppm, and Br + Cl ≤ 1,500 ppm.
