### EE2-5TNKX-R6: Component Overview The **EE2-5TNKX-R6** is a miniature, surface-mount (SMD) signal relay manufactured by KEMET. It belongs to the EE2 series, which is highly regarded for its compact size, high reliability, and low power consumption in telecommunications and instrumentation applications. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Relay Type** | Polarized, Latching (Non-latching variants exist, but "T" indicates Latching) | | **Contact Form** | 2 Form C (DPDT - Double Pole Double Throw) | | **Coil Voltage** | 5 VDC | | **Coil Resistance** | 178 $\Omega$ (approx.) | | **Contact Rating** | 30W / 62.5VA (Max 220VDC / 250VAC) | | **Max Switching Current** | 2A | | **Mounting Type** | Surface Mount (SMD) - R-Type Lead | | **Dielectric Strength** | 1000 VAC (between open contacts) | --- ### 2. Breakdown of the Part Number Understanding the suffix helps identify specific features: * **EE2**: Series name (Miniature Signal Relay). * **5**: Nominal coil voltage (5V). * **T**: Latching type (Single coil). * **NKX**: Specific internal design/material variations (often related to high breakdown voltage or specific contact materials). * **R6**: Refers to the lead shape and packaging (R-type lead for SMD, typically supplied in tape and reel). --- ### 3. Functional Features #### A. Latching Mechanism Unlike standard non-latching relays that require continuous power to stay "on," the **T** designation indicates this is a **latching relay**. It uses a permanent magnet to hold the contacts in position. A short pulse of power switches the state, and it remains in that state without further power, making it ideal for battery-operated devices. #### B. DPDT Configuration (2 Form C) It features two independent sets of Changeover (CO) contacts. This allows the relay to control two separate circuits simultaneously or reverse the polarity of a single DC motor. #### C. High Sensitivity The EE2 series is designed for low power consumption, allowing it to be driven by standard logic gates or microcontrollers (often requiring a transistor or relay driver due to the current draw). --- ### 4. Typical Applications * **Telecommunications:** Switching test equipment and PBX systems. * **Measurement Equipment:** Oscilloscopes and signal generators. * **Medical Electronics:** Portable diagnostic devices. * **Home Automation:** Low-power switching in smart thermostats. ---
