30A BLDC ESC Electronic Speed Controller with Connectors
[ESC] 30A BLDC ESC Electronic Speed Controller is specifically made for quadcopters and multi-rotors. Which provides faster and better motor speed control giving better flight performance compared to other available ESCs. 30A BLDC ESC Electronic Speed Controller can drive motors that consume current up to 30A. It works on 2-3S LiPo batteries. This electronic speed controller offers a battery eliminator circuit (BEC) that provides 5V and 2A to the receiver so we don’t need an extra receiver battery. This version of the ESC also includes backward-polarity protection and protection on the 5V receiver line, this means that if you accidentally attach a battery backward it won’t destroy your motor controller and other BEC won’t affect the ESC. If you are wandering to build a drone and don’t know what will be the best ESC for you then worry no more, we have got your back. At , we have everything for you to get started with your drone project. This particular ESC is recommended with A2212 brushless motor (1000kv, 1400kv, 2200kv). For your Convenience Same ESC without Connectors is also available Connections: 30A ESC wiring (Other products not included in this package): Warning: When we connect BLDC ESC directly to the remote control receiver; never ever switch off the remote control before switching off power to the BLDC ESC. Depending on the model of the remote control; it may result in full throttle applied to the motor and it will rotate at full speed. Features: High-quality MOSFETs for BLDC motor drive. Backward-polarity protection and protection on the 5V receiver line. High-performance microcontroller for best compatibility with all types of motors at greater efficiency. Fully programmable with any standard RC remote control. Heat sink with a high-performance heat transmission membrane for better thermal management. 3 start modes: Normal / Soft / Super-Soft, compatible with fixed-wing aircraft and helicopters. We can configure the throttle range to be compatible with any remote control available in the market. Package Includes: 1 x 30A BLDC ESC Electronic Speed Controller with Connectors.
Keltron 2200uF 25V Radial Electrolytic Capacitor High Performance Capacitor
[Through Hole Capacitor] The 2200uF 25V Electrolytic Capacitor is a high-capacitance aluminum electrolytic capacitor designed for energy storage, voltage filtering, and decoupling applications. It is widely used in power supplies, audio amplifiers, industrial electronics, and electronic repair projects. In addition, the capacitor provides excellent ripple current handling and stable electrical performance. As a result, it effectively reduces voltage fluctuations, suppresses electrical noise, and improves overall circuit reliability. Because of its 2200uF capacitance, this capacitor can store a significant amount of electrical energy for smoothing DC outputs and reducing transient voltage spikes. Furthermore, the 25V rated voltage makes it suitable for a wide range of low-voltage power supply applications. The radial lead design allows easy PCB mounting and convenient installation. Moreover, the capacitor is manufactured using high-quality aluminum electrolytic technology to ensure long service life and dependable operation.
