Product Introduction

Product Overview

The Sinyinda SYCBCJY3PF is a compact 3-position signal connector female socket, designed to resolve the contradiction between cramped internal space in modern electronic devices and the stability of signal transmission. This series employs high-precision mold forming, with the insulator made of high-quality PA material, offering excellent flame retardancy and mechanical strength. The core conductive components use a copper base with a gold-plated (1μm) surface treatment, effectively preventing oxidation and corrosion, ensuring extremely low contact resistance even during long-term storage or in harsh environments. Its compact 20mm length design makes it an ideal choice for PCB board-end connections in model aircraft flight controllers, portable medical devices, and various sensor modules.

Product Introduction

  • Precision Gold-Plating Process:The contacts use copper gold-plating (1μm) treatment. Compared to standard tin or nickel plating, the gold layer offers unparalleled oxidation resistance and wear durability, making it especially suitable for weak signal transmission and high-frequency insertion/withdrawal scenarios, eliminating "false connections" and signal packet loss.
  • Ultra-Compact Design:The overall dimensions are only 20.0 x 10.7 x 8.7mm, with a mounting hole pitch of 15.9mm, greatly saving PCB routing space and meeting the layout requirements of handheld devices and miniaturized modules where "every inch of space is precious."
  • High-Reliability Structure:The internal spring contacts are precisely calculated for mechanical force, providing stable normal pressure to ensure tight contact even after 2000 insertion/withdrawal cycles; the external insulator surface is smooth and burr-free, complies with RoHS environmental standards, and adapts to a wide operating temperature range of -20°C to 100°C.
  • Wide Application Compatibility:Standard 3-Pin definition, with strong universality, can perfectly replace similar old models on the market. Widely used in fields such as drone battery balance charging interfaces, industrial sensor signal acquisition, and smart instrument communication ports.

Engineer's Selection Guide

When selecting the SYBCJY3PF for your project, please pay special attention to the following engineering parameters:

  1. Current Load Evaluation:This female connector has a rated current of 5A and a transient current of up to 7A. If your application involves continuous high current (>5A) or motor startup surges, it is recommended to consider our high-current series (such as the SYBCWL series); if it is only for signal transmission or low-power supply (such as sensors, LED drivers, balance chargers), this model is the best cost-effective choice.
  2. Environmental Tolerance:Although PA material offers good temperature resistance (-20°C to 100°C), if the application environment involves strong acid/alkali corrosion or long-term outdoor exposure, it is recommended to confirm whether the housing requires additional conformal coating protection or the use of a special engineering plastic version.
  3. PCB Package Matching:Be sure to verify the pad size drawing (Footprint) in the datasheet. This product has a pin diameter of 1.7mm, a pitch of 3.3mm, and a mounting hole diameter of 2.2mm. When designing the PCB, it is recommended to reserve a process tolerance of 0.1-0.2mm to ensure the yield rate of automated insertion or manual soldering.
  4. Mating Cycle Life Expectation:The design life is 2000 cycles. For consumer interfaces with frequent plugging and unplugging (such as multiple times daily), this lifespan fully meets usage requirements for over 5 years; if it is an internal fixed connection (never unplugged throughout its life), its reliability redundancy is extremely high.
