The **FAP-61-R** is an electronic component primarily manufactured by **Fujisoku** (a brand under Nidec Components). It is a high-precision, low-profile **Tactile Switch** designed for surface mount applications. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The FAP-61-R belongs to the FAP series of subminiature switches, known for their tactile feedback and durability. | Feature | Specification | | :--- | :--- | | **Type** | SPST (Single Pole Single Throw), Normally Open | | **Mounting Type** | SMT (Surface Mount Technology) | | **Actuation Force** | 1.57N (approx. 160gf) | | **Travel (Stroke)** | 0.25mm | | **Operating Life** | 100,000 cycles (minimum) | | **Operating Temperature** | -25°C to +70°C | --- ### 2. Electrical Characteristics These parameters define the limits under which the switch can safely operate without electrical failure or excessive heat generation. * **Current Rating:** Typically 50mA. * **Voltage Rating:** 12V DC. * **Contact Resistance:** 100mΩ maximum (initial). * **Insulation Resistance:** 100MΩ minimum (at 100V DC). * **Dielectric Strength:** 250V AC for 1 minute. --- ### 3. Physical & Material Composition The construction of the FAP-61-R is optimized for automated assembly (Pick-and-Place). * **Dimensions:** Roughly 6mm x 6mm (Standard footprint). * **Plating:** Contact points are usually **Silver-plated** to ensure high conductivity and oxidation resistance. * **Body Material:** High-temperature thermoplastic (PPS or LCP) to withstand reflow soldering temperatures. * **Actuator:** Soft-touch or hard-top depending on the specific sub-variant, designed for human-machine interface (HMI). --- ### 4. Typical Applications The "R" suffix often denotes **Tape and Reel** packaging, making it suitable for mass production in: 1. **Consumer Electronics:** Remote controls, cameras, and audio equipment. 2. **Industrial Controls:** Control panels and PLCs. 3. **Medical Devices:** Portable diagnostic tools. 4. **Automotive:** Dashboard buttons and infotainment systems. ---
