series introduction

# Introduction to the JMK105BBJ475MV - F Product Series

## 1. Overview
The JMK105BBJ475MV - F product series belongs to the realm of electronic components, specifically ceramic multilayer capacitors. These capacitors are essential building blocks in modern electronic circuits, playing a crucial role in a wide range of applications due to their unique electrical properties and reliable performance.

## 2. Product Specifications

### Physical Dimensions
The "105" in the model number indicates the size of the capacitor. In the standard EIA (Electronic Industries Alliance) code, this typically corresponds to a 0603 package size. The 0603 package has dimensions of approximately 1.6mm x 0.8mm, making it a relatively small - sized component. This compact size is highly advantageous in modern electronic devices where space is at a premium, such as smartphones, wearables, and other portable electronics.

### Capacitance
The "475" in the model number represents the capacitance value of the capacitor. Using the standard capacitor value coding system, the first two digits (47) are the significant figures, and the third digit (5) is the multiplier. So, the capacitance value is calculated as \(47\times10^{5}\) picofarads (pF), which is equal to 4.7 microfarads (\(\mu F\)). This relatively high capacitance value allows the capacitor to store a significant amount of electrical charge, making it suitable for applications that require energy storage and filtering.

### Voltage Rating
The "J" in the model number indicates the tolerance of the capacitor, which is ±5%. The "475" is followed by "MV", which represents the voltage rating. In this case, the capacitor has a rated voltage of 16V. This means that the capacitor can safely operate in circuits where the voltage across it does not exceed 16V. It is important to note that operating the capacitor within its rated voltage is crucial to ensure its long - term reliability and performance.

### Dielectric Material
The "B" in the model number typically indicates the type of dielectric material used in the capacitor. For ceramic capacitors, different dielectric materials offer different electrical properties. The B - type dielectric is often a Class II dielectric, which provides a relatively high capacitance per unit volume but may have some temperature - dependent characteristics. However, it is still suitable for a wide range of general - purpose applications.

### Temperature Coefficient
The temperature coefficient of the JMK105BBJ475MV - F capacitor is designed to meet specific requirements. Class II dielectric capacitors like this one usually have a temperature coefficient that may vary with temperature. However, the manufacturer has engineered the product to maintain stable performance within a certain temperature range, typically from - 55°C to +125°C. This wide temperature range makes the capacitor suitable for use in various environmental conditions.

## 3. Electrical Performance

### Capacitance Tolerance
As mentioned earlier, the capacitor has a tolerance of ±5%. This means that the actual capacitance value of the capacitor may vary within 5% of the nominal value (4.7\(\mu F\)). For example, the actual capacitance could range from \(4.7\times(1 - 0.05)\) \(\mu F=4.465\mu F\) to \(4.7\times(1 + 0.05)\) \(\mu F = 4.935\mu F\). This level of tolerance is acceptable for many general - purpose applications, but in some precision circuits, a tighter tolerance may be required.
