The **FTS-41-R** is an electronic component primarily classified as a **Precision Quartz Crystal** or **Crystal Oscillator** (depending on the specific manufacturer series, often associated with brands like Fox Electronics or CTS). It is designed to provide a stable frequency reference for electronic circuits. --- ### 1. Key Technical Specifications Below is a breakdown of the typical technical parameters for the FTS-41-R series: | Parameter | Typical Value / Range | | :--- | :--- | | **Frequency Range** | 1.0 MHz to 100.0 MHz (Application dependent) | | **Package Type** | Thru-Hole (often HC-49 style or similar low-profile) | | **Tolerance** | ±30ppm to ±50ppm | | **Operating Temperature** | -10°C to +70°C (Standard) | | **Load Capacitance** | 12pF to 32pF or Series | | **Mounting Style** | Radial Lead (R-suffix often denotes radial/thru-hole) | --- ### 2. Physical Characteristics The "R" suffix in parts like the FTS-41-R frequently refers to specific physical orientations or packaging styles: * **Radial Configuration:** The leads are oriented to be inserted through holes in a Printed Circuit Board (PCB). * **Hermetic Sealing:** These parts are typically sealed in a metal can to prevent environmental moisture or gases from affecting the quartz crystal's oscillation stability. * **Compact Footprint:** Designed for applications where vertical space is available but PCB surface area is limited. --- ### 3. Electronic Function & Circuitry The FTS-41-R functions as the "heartbeat" of a circuit. Here is how it is integrated: #### Internal Composition The device consists of a thin slice of quartz crystal placed between two electrodes. Due to the **Piezoelectric Effect**, applying an electric field causes the crystal to vibrate at a very specific, stable frequency. #### Typical Application Circuit In a microprocessor or microcontroller circuit, the crystal is usually connected to the `XTAL1` and `XTAL2` pins with two load capacitors. ```c // Pseudo-code representation of Oscillator Setup void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; // Enable the Crystal Oscillator (HSE) RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE; RCC_OscInitStruct.HSEState = RCC_HSE_ON; // Using the FTS-41-R HAL_RCC_OscConfig(&RCC_OscInitStruct); } ``` --- ### 4. Common Applications * **Microcontrollers:** Providing the clock signal for CPUs (e.g., Arduino, STM32). * **Communication Equipment:** Stabilizing frequencies for RF transmitters and receivers. * **Consumer Electronics:** Used in digital watches, televisions, and household appliances. * **Industrial Control:** Ensuring synchronized timing in automation systems. ---
