Description

A 200K Ohm 1/4W 1% 1206 SMD Chip Resistor is a high-precision surface-mount device (SMD) resistor designed for use in a wide variety of electronic circuits. Here's a detailed breakdown of its key characteristics:

1. Resistance Value: The resistor has a resistance of 200K Ohms, which means it resists the flow of electrical current by 200,000 ohms. This resistance value is commonly used in signal processing, voltage dividers, and other precise applications in digital and analog circuits.

2. Power Rating: With a 1/4 Watt (or 0.25W) power rating, this resistor is designed to dissipate up to 0.25 watts of power without overheating or damaging the component. This is a common power rating for resistors used in general-purpose applications, ensuring reliability in everyday electronic devices.

3. Tolerance: This resistor has a 1% tolerance, meaning the actual resistance value can vary by ±1% from its nominal value of 200K Ohms. This level of tolerance makes the resistor suitable for applications where moderate precision is acceptable, such as in standard consumer electronics, signal processing, and control systems.

4. Package Size: The resistor comes in a 1206 SMD package size, which measures 3.2 mm x 1.6 mm. This compact size is typical for modern surface-mount technology (SMT), allowing it to be easily placed on circuit boards during automated assembly. The small size also makes it ideal for space-constrained designs while maintaining a balance between performance and footprint.

5. Applications: This resistor is commonly used in electronic circuits requiring stable and reliable resistance values. Typical applications include:

   • Voltage Dividers: Used in analog circuits to scale voltages or create specific reference voltages.
   • Signal Processing: Helps in filtering, attenuating, or conditioning electrical signals in audio or radio-frequency applications.
   • Load Resistors: Used in power management and battery testing circuits.
   • General Circuit Design: Any general-purpose circuit requiring a 200K ohm resistance value with a 1/4 watt power rating.

6. Material and Construction: Typically, SMD resistors like this one are made from a combination of ceramic and metal oxide materials to achieve stability, durability, and accurate performance over a wide range of operating conditions, including temperature and humidity fluctuations.

7. Temperature Coefficient: While not explicitly specified in the description, most resistors of this type typically have a temperature coefficient in the range of ±100 ppm/°C. This means that the resistance value can change by up to 100 parts per million per degree Celsius of temperature change. In applications requiring stable performance under temperature variations, choosing resistors with a low temperature coefficient is essential.

In summary, the 200K Ohm 1/4W 1% 1206 SMD Chip Resistor is a small, precise, and reliable component used in a wide array of electronic applications. Its combination of resistance, power rating, size, and tolerance makes it suitable for a variety of consumer and industrial electronics designs, ensuring it meets the needs of compact, high-performance circuits.
