The **EE2-5SNKX-R** is a specific model of a miniature signal relay manufactured by KEMET (formerly NEC). It is widely used in telecommunications, testing equipment, and medical devices due to its compact size and high reliability. --- ## 1. Technical Specifications The model name contains specific configuration data. Here is the breakdown of the technical characteristics: | Feature | Specification | | :--- | :--- | | **Contact Form** | DPDT (2 Form C) | | **Coil Voltage** | 5 VDC | | **Coil Type** | Single Coil Latching | | **Contact Rating** | 30 W, 62.5 VA (2A Max, 220VDC / 250VAC) | | **Package Style** | Surface Mount (SMT) | | **Termination** | Gull-wing (NK type) | | **Packaging** | Tape & Reel (-R) | --- ## 2. Key Features ### A. Latching Mechanism Unlike standard non-latching relays, the **EE2-5SNKX-R** is a **single-coil latching** relay. * **Function:** It maintains its state (open or closed) even after power is removed from the coil. * **Benefit:** Extremely low power consumption, as energy is only required to flip the switch, not to hold it. ### B. High Reliability * **Low Power Consumption:** Uses only 100mW - 140mW during switching. * **Dielectric Strength:** Offers high breakdown voltage between contacts and coil (usually around 1500V AC). * **Compact Design:** The EE2 series is designed for high-density mounting on PCBs. ### C. Mounting Style (NK) The "NK" suffix refers to the lead shape. These are "Gull-wing" SMT leads, which provide high solderability and allow for visual inspection of the solder joints after assembly. --- ## 3. Typical Applications Because of its sensitivity and signal integrity, this relay is commonly found in: 1. **Telecommunications:** Switching between line circuits. 2. **Instrumentation:** Oscilloscopes and multimeters for range switching. 3. **Medical Equipment:** Small-signal isolation in diagnostic tools. 4. **Battery Powered Devices:** Due to the latching nature saving battery life. --- ## 4.
