SRP7030-3R3FM

Fixed inductors play a crucial role in the circuit layout of numerous electronic devices. They are generally classified into two main categories: ferrite bead inductors and wire wound inductors. The SRP7030-3R3FM inductor falls in the wire wound category as it contains a copper, wire-like material wound around a ferrite rod. It is designed for surface mount applications and is one of the most common types of inductors used in the electronics industry.

The SRP7030-3R3FM is a SMD-style fixed inductor with a winding pitch of 0.125 mm and a rated inductance of 3.3μH. It has a rated saturation current of 770 mA, a rated DC current of 1.15 A and a tolerance of ±10%. This device is well suited for applications such as buffering and decoupling applications, filtering and noise suppression, linear regulator inputs and high current switching applications.

The construction of the device consists of a copper winding which is wound around a ferrite rod. The copper wire is encapsulated in molded molding compound which ensures that the inductance remains stable during operation. Lightweight and compact, it is ideal for surface mounted applications due to its low profile design. This reduces the space required on the circuit board.

As for its working principle, the SRP7030-3R3FM is primarily based on the principle of inductance, meaning that when a conductor is exposed to a changing magnetic field, it induces a proportional amount of electrical current. This is the core concept behind the operation of this device. As the amount of current flowing through the coil of the device is altered, the inductance will change as well. This change in inductance affects the device’s resistance which helps to regulate the output current and voltage of the circuit.

The SRP7030-3R3FM is generally recommended for applications that require high current accuracy and efficiency. Being designed to function in applications with a maximum operating temperature of +125°C, it is also suitable for use in high temperature environments. Additionally, this device also has rated voltage of 2.5V and an insulation resistance of 10MΩ, making it suitable for use in circuits with high voltage and power applications.

All in all, the SRP7030-3R3FM is a compact, lightweight, SMD-style inductor which is designed for use with surface mount circuitry. It is based on the principle of inductance and provides high efficiency, good accuracy and a high temperature rating. Due to its excellent performance and reliability, it is well suited for a range of commercial and industrial applications.
