# ERZ - C20EK471 Product Series Introduction
## 1. Overview
The ERZ - C20EK471 product series represents a cutting - edge solution in the field of electronic components. Engineered with precision and innovation, this series is designed to meet the diverse and demanding requirements of modern electronic applications. Whether it's for consumer electronics, industrial automation, or telecommunications, the ERZ - C20EK471 series offers reliable performance and advanced functionality.
## 2. Key Features
### 2.1 High - Quality Construction
- The components in the ERZ - C20EK471 series are built using high - grade materials. This ensures excellent durability and resistance to environmental factors such as temperature variations, humidity, and mechanical stress. For example, the outer casing is made of a robust polymer that can withstand impacts and vibrations, protecting the internal components from damage.
- The internal circuitry is fabricated with precision using state - of - the - art manufacturing processes. This results in consistent electrical performance across all units in the series, minimizing variations and ensuring reliable operation.
### 2.2 Precise Electrical Characteristics
- These components offer highly accurate electrical values. In the case of the ERZ - C20EK471, it has a specific capacitance value (in this case, related to the '471' in the model number, which typically indicates a capacitance value following a certain coding convention). The capacitance is tightly controlled during the manufacturing process, with a tolerance level that is significantly lower compared to many standard components in the market. This precision is crucial for applications where accurate electrical performance is essential, such as in filter circuits or timing circuits.
- The series also exhibits low equivalent series resistance (ESR). A low ESR means that the component can handle high - frequency signals more efficiently, reducing power losses and heat generation. This is particularly beneficial in high - speed electronic circuits where minimizing energy consumption and maintaining signal integrity are key concerns.
### 2.3 Wide Operating Temperature Range
- The ERZ - C20EK471 series is designed to operate effectively over a wide temperature range. It can function reliably in temperatures as low as - 40°C and as high as 125°C. This wide temperature tolerance makes it suitable for a variety of environments, from cold storage facilities to high - temperature industrial settings.
- The ability to maintain stable performance across different temperatures is achieved through the use of advanced materials and thermal management techniques. For instance, the internal dielectric material is selected for its temperature - stable properties, ensuring that the electrical characteristics of the component remain consistent even as the temperature changes.
### 2.4 Compact Design
- The components in this series feature a compact form factor. This is a significant advantage in modern electronic devices, where space is often at a premium. The small size allows for more efficient use of printed circuit board (PCB) space, enabling designers to create smaller and more densely packed electronic products.
- Despite their small size, the ERZ - C20EK471 components do not compromise on performance. They are able to deliver the same level of functionality as larger components, making them an ideal choice for applications such as mobile devices, wearables, and miniaturized industrial sensors.
## 3. Applications
### 3.1 Consumer Electronics
- In smartphones and tablets, the ERZ - C20EK471 series can be used in power management circuits. Its low ESR and high - precision capacitance help to filter out noise and stabilize the power supply, ensuring smooth operation of the device.
- For audio equipment, such as headphones and speakers, these components can be used in audio filter circuits. The accurate electrical characteristics of the series contribute to high - quality sound reproduction by filtering out unwanted frequencies and enhancing the clarity of the audio signal.
