The Hc 49us Datasheet. It might sound technical, but it’s your key to understanding and utilizing a very common and crucial component in electronics: the quartz crystal. These crystals, oscillating at specific frequencies, are the heartbeats of countless devices, from watches to computers. This document provides the vital information needed to integrate them correctly into your designs.
Deciphering the Hc 49us Datasheet The Core Information
The Hc 49us Datasheet is essentially a technical manual. It details all the critical electrical and physical characteristics of the Hc 49us crystal. This information is crucial for ensuring your circuit functions as intended and avoids potential problems like instability or damage. Accurate interpretation and adherence to the datasheet specifications are paramount for reliable performance. The datasheet covers parameters such as:
- Frequency Tolerance: How much the actual frequency can deviate from the specified value.
- Load Capacitance: The capacitance value the crystal “expects” to see in the circuit.
- Operating Temperature Range: The temperature range within which the crystal will function reliably.
So, how exactly are Hc 49us crystals used? They are used in circuits to generate precise timing signals. Think of them as tiny, highly accurate clocks. They are found in microcontrollers, oscillators, and many other electronic circuits where stable frequency control is required. When designing a circuit using an Hc 49us crystal, you must carefully consider the parameters listed in the datasheet. Choosing the wrong load capacitance or exceeding the operating temperature range can lead to frequency inaccuracies or even cause the crystal to fail. For example, consider these common applications:
- Microcontroller Clock Source: Provides a stable and accurate clock signal for the microcontroller’s operation.
- Real-Time Clocks (RTCs): Used to keep track of the current time with high precision.
- Frequency Synthesizers: Used to generate a wide range of frequencies based on a stable crystal oscillator.
Let’s say you’re building a simple oscillator circuit. You’ll need to know the crystal’s series resistance (ESR) to properly bias the amplifier. You’ll also need to ensure the load capacitance of your circuit matches the crystal’s specified load capacitance for optimal frequency accuracy. The datasheet helps you choose the right components and configure your circuit for the best performance. Incorrect values can cause your device to operate at the wrong frequency, or not operate at all. It also provides physical dimensions, crucial for PCB layout and mechanical integration, as shown in this table:
| Parameter | Typical Value |
|---|---|
| Height | 3.5 mm |
| Length | 11.0 mm |
| Width | 4.5 mm |
To make sure you get the best possible results from your Hc 49us crystal, it’s vital to consult the official Hc 49us Datasheet. Inside the datasheet, you will find the manufacturer’s recommended operating conditions, performance graphs, and other essential information.
