Overview
The GE 29F730 is a polarized axial aluminum electrolytic capacitor designed for general-purpose DC filtering, energy storage, and timing applications. With a capacitance rating of 40µF and a maximum operating voltage of 30V DC, this component delivers reliable performance in industrial, commercial, and consumer electronic equipment. The axial lead configuration simplifies breadboard and PCB integration, while the aluminum electrolytic construction provides a proven, cost-effective solution for power supply decoupling and smoothing.
Key Features
- Polarized design—positive and negative terminals must be observed for correct circuit operation
- Axial lead termination for easy mounting on PCB or breadboard
- Aluminum electrolytic construction for stable performance across temperature ranges
- 40µF capacitance with ±20% tolerance typical for aluminum electrolytic type
- 30V DC working voltage rating—do not exceed applied voltage
- Compact form factor suitable for space-constrained applications
