The part number **11252-R2** is most commonly associated with specialized hardware components, specifically high-quality **RF (Radio Frequency) connectors** or precision **Electronic Spacers/Stand-offs**. However, in the context of global supply chains, it is most frequently identified as a **Right-Angle MMCX Connector** or a specific **Precision Spacer** used in PCB assembly. --- ### 1. Technical Specifications (General Guide) Depending on the manufacturer (such as Amphenol or Keystone), here are the typical specifications for a part labeled 11252-R2: | Feature | Specification | | :--- | :--- | | **Type** | Right-Angle Plug / PCB Mount | | **Interface** | MMCX (Micro-Miniature Coaxial) | | **Impedance** | 50 Ohms | | **Frequency Range** | DC to 6 GHz | | **Body Material** | Brass / Gold Plated | | **Insulator** | PTFE (Teflon) | | **Contact Resistance** | < 5.0 mΩ | --- ### 2. Common Applications This electronic part is typically used in high-density circuit environments where space is limited but signal integrity is crucial. * **Wireless Communication:** Used in Wi-Fi routers and GPS modules. * **Instrumentation:** Signal routing in handheld testing equipment. * **Medical Electronics:** High-frequency imaging components. * **PCB Spacing:** If identified as a hardware spacer, it is used to maintain strict gaps between stacked circuit boards to prevent short circuits. --- ### 3. Usage Best Practices When integrating the 11252-R2 into a design, consider the following: 1. **Soldering Temperature:** Ensure the soldering profile does not exceed the melting point of the internal PTFE insulator (usually ~260°C). 2. **Mating Cycles:** MMCX connectors are rated for roughly 500 mating cycles. Excessive plugging/unplugging can degrade signal quality. 3. **Shielding:** To reduce EMI (Electromagnetic Interference), ensure the outer body is properly grounded to the PCB plane. --- ### 4.
