Based on the part number **K5Q7AN-R**, this component is a specific type of **Miniature Power Relay** manufactured by **Panasonic** (formerly NAiS). These relays are widely used in automotive and industrial applications due to their compact size and high switching capacity. --- ## 1. Technical Specifications The "K" series relays from Panasonic are known for their reliability in high-current environments. Below are the typical technical parameters for the K5Q7AN-R: | Feature | Specification | | :--- | :--- | | **Component Type** | Electromechanical Relay | | **Contact Arrangement** | 1 Form A (SPST-NO) or 1 Form C (SPDT) | | **Coil Voltage** | 12V DC (Standard for Automotive) | | **Max Switching Current** | 20A to 30A (Load dependent) | | **Terminal Type** | PCB Mount (Through-hole) | | **Seal Rating** | Sealed (Protection against dust and flux) | | **Operating Temperature** | -40°C to +85°C | --- ## 2. Pinout and Internal Structure The "R" suffix often denotes a specific resistor or diode internal to the relay for **Coil Surge Suppression**. * **Coil (Pins 1 & 2):** When 12V is applied, the electromagnetic field pulls the contact. * **Common (COM):** The input terminal for the load. * **Normally Open (NO):** The contact that closes when the relay is energized. * **Internal Protection:** The **-R** indicates a resistor is wired in parallel with the coil to prevent voltage spikes from damaging sensitive control electronics (like an ECU). --- ## 3. Common Applications Due to its high current rating and small footprint, this part is frequently found in: 1. **Automotive Systems:** Power windows, central locking, fuel pumps, and fan controls. 2. **Industrial Control:** Small motor starters and PLC output modules. 3. **Consumer Electronics:** High-power appliances requiring PCB-mounted switching. --- ## 4. Equivalent / Replacement Parts If you are looking for a replacement, ensure the footprint and coil resistance match. Common alternatives include: * **Omron:** G8N-1 series. * **TE Connectivity:** V23084 series.
