Overview and Application Notes
-
Overview : The BSDF11B1N1115 is a high-reliability, surface-mount (SMT) SD card connector engineered for secure memory expansion in compact and demanding electronics. Featuring a built-in normally-open (NO) card detection switch and durable copper alloy contacts (0.5A rated), this connector ensures stable data transmission and robust mechanical retention. Constructed with a high-temperature LCP (UL94V-0) housing and a shielded outer shell, it operates reliably across a temperature range of -25°C to +85°C. With a proven durability of 10,000 mating cycles, it provides an ideal storage I/O solution for tablets, industrial data loggers, and automotive infotainment systems.

Application Notes :
-
PCB Footprint & Assembly: The surface-mount (SMT) design requires accurate solder paste application to ensure strict pad coplanarity. Thanks to its Hi-Temp LCP housing, the connector is fully compatible with standard RoHS lead-free reflow soldering profiles.
-
Card Detection System: Integrates a normally-open (NO) switch that closes upon successful card insertion. Engineers should route this CD pin to the system microcontroller to reliably trigger memory mounting and dismounting sequences.
-
Grounding & Retention: Ensure the outer metallic shell mounting pads are fully soldered to the PCB ground plane. This not only minimizes EMI (Electromagnetic Interference) susceptibility but also maximizes mechanical peel strength to withstand repeated card insertions and extractions.
