CD75-1R0

Overview

The CD75-1R0 is a radial-lead aluminum electrolytic capacitor designed for high-performance applications in power supply circuits and industrial electronics. Known for its reliability and durability, it is commonly used in devices requiring stable voltage regulation and noise filtering. This capacitor is part of the CD75 series, which is recognized for its low Equivalent Series Resistance (ESR) and high capacitance values. Its construction ensures long operational life, making it a preferred choice for demanding environments.

Structure and Working Principle

The CD75-1R0 consists of an aluminum anode foil, a cathode foil, and an electrolyte solution, all housed in an aluminum can. The anode foil is etched to increase surface area, enhancing capacitance. A paper separator soaked in electrolyte facilitates ion flow between the foils. When voltage is applied, an oxide layer forms on the anode foil, acting as the dielectric. This layer allows the capacitor to store and release energy efficiently, stabilizing voltage and filtering out electrical noise in circuits.

Key Features

The CD75-1R0 offers several advantages, including high capacitance (typically 1.0μF), low ESR, and a wide operating temperature range (-40°C to +105°C). These features make it suitable for high-frequency and high-temperature applications. Additionally, its radial lead design simplifies PCB mounting, and its robust construction ensures resistance to vibration and mechanical stress, enhancing reliability in industrial settings.

Application Areas

This capacitor is widely used in power supply units, inverters, motor drives, and consumer electronics like televisions and audio equipment. Its ability to handle high ripple currents makes it ideal for switching power supplies. In industrial applications, the CD75-1R0 is often found in automation systems, renewable energy systems, and telecommunications infrastructure, where stable performance under varying conditions is critical.

Maintenance and Precautions

To ensure longevity, avoid exposing the CD75-1R0 to reverse polarity, voltages exceeding its rated value, or temperatures beyond its specified range. Improper handling can lead to reduced performance or failure. Storage in humid environments should be avoided to prevent degradation of the electrolyte. Regular inspection for bulging or leakage is recommended, especially in high-stress applications.

B2B Procurement Guide

When procuring CD75-1R0 capacitors, verify supplier certifications (e.g., ISO 9001) to ensure quality. Bulk purchases typically offer cost savings, but ensure compatibility with your application’s voltage and capacitance requirements. Lead times can vary, so plan orders in advance, especially for large quantities. Reliable suppliers often provide technical support and datasheets to assist with integration.
