SlimStack 527600478 Board to Board Micro Connector Fmale, sometimes simply referred to as a female board-to-board connector or a receptacle, is an electrical connector designed to provide the female or receptacle side of a connection between two printed circuit boards

 Introdction：

SlimStack 527600478 Board to Board Micro Connector Female stands out with its exquisite exterior design. Its pin spacing is only 0.635mm, which greatly saves circuit board space while ensuring stable connection. The combined height of 3.0mm and width of 6.4mm have taken thinness to the extreme, providing strong support for the miniaturization of electronic devices. In products such as smartphones and wearable devices where space is scarce, this compact connector can easily adapt without taking up too much valuable space, making the internal layout of the device more compact and reasonable.

Its performance characteristics：

Current and voltage carrying capacity: The rated current reaches 0.5A (AC/DC) and the rated voltage is 50V (AC/DC), which can meet the low-power power supply and signal transmission needs of small and medium-sized electronic devices, and adapt to the conventional power specifications of consumer electronics, smart homes and other scenarios.

Low contact resistance: The maximum contact resistance is only 30 milliohms, effectively reducing energy loss during signal transmission, lowering the risk of heat generation, and ensuring the stability and efficiency of current and signal transmission.

Excellent insulation performance: The minimum insulation resistance is 100 megaohms (under 100V DC conditions), combined with 100V AC/1-minute voltage resistance, which can effectively isolate interference between circuits, prevent short circuits or leakage phenomena, and improve equipment operation safety.

Wide working temperature range:SlimStack 527600478 Board to Board Micro Connector Female can work stably in environments ranging from -20 ℃ to+105 ℃, and can withstand material shrinkage tests in low-temperature environments as well as performance degradation in high-temperature scenarios. It is suitable for various indoor and outdoor use environments.

High temperature resistant shell: The shell is made of UL94V-0 grade high-temperature plastic (LCP), which has excellent heat resistance and flame retardancy, and can withstand high temperature environments during welding and equipment operation, extending its service life; The white appearance facilitates visual recognition and installation verification.

High conductivity contacts: SlimStack 527600478 Board to Board Micro Connector Female are made of phosphor bronze material, combined with gold plating technology, which not only ensures good conductivity and elasticity, but also improves corrosion resistance and wear resistance, reducing the risk of poor contact during long-term use and ensuring connection stability.

SlimStack 527600478 Board to Board Micro Connector Female core application areas mainly focus on electronic device scenarios with clear requirements for low power consumption, high reliability, environmental adaptability, and miniaturization, including:

1.In the field of consumer electronics                                                                                                                                                                                                                                          Internal signal interfaces for smartphones and tablets (connecting motherboards to screens, cameras, and other modules), power and data transmission interfaces for small wearable devices (smartwatches, bracelets), and internal circuit connections for portable small appliances (mini fans, power banks).
Adaptation reason: The low rated current (0.5A) and voltage (50V) meet the low-power requirements of consumer electronics, and the small size design (combined with the miniaturization characteristics of the Slimstack series) adapts to the compact internal space of the device. The wide temperature range (-20 ℃ to+105 ℃) can cope with temperature fluctuations in daily use.

2. Smart homes and IoT devices
• Includes circuit connections for smart sensors (temperature and humidity sensors, lighting sensors), internal interfaces for small smart home controllers (such as smart switches, curtain motor control modules), and power and signal transmission for low-power IoT terminals (such as Wi Fi modules, Bluetooth gateways).
Adaptation reason: Excellent insulation performance (100M Ω insulation resistance, 100V withstand voltage) enhances the electrical safety of equipment, gold-plated contacts and phosphor bronze material ensure long-term stable connection, meeting the needs of “low maintenance, long life” of smart home devices.

3. Industrial control and small instruments and meters
Suitable for signal output interfaces of small industrial sensors (such as miniature pressure sensors, proximity switches), as well as internal circuit connections of portable instruments and meters (such as handheld thermometers, small multimeters).
Adaptation reason: The wide temperature range can withstand temperature changes in industrial environments, and the high-temperature resistant LCP shell (UL94V-0 flame retardant rating) improves the reliability of the equipment in complex environments. The low contact resistance (≤ 30m Ω) reduces signal transmission errors and ensures data accuracy.

4. Automotive electronic auxiliary equipment
SlimStack 527600478 Board to Board Micro Connector Female mainly used for low-power electronic accessories inside cars, such as small sensors in cars (temperature and humidity sensors, seat pressure sensors), internal interfaces for car USB charging modules, or signal connections for driving recorders and reversing image modules.
Adaptation reason: The wide temperature range can cope with high temperature (summer exposure) and low temperature (winter cold) environments inside the car. The flame-retardant shell and insulation performance reduce the electrical safety hazards inside the car, meeting the basic stability requirements of automotive electronics.
