Chokes Made in Germany – Tailored to Your Requirements
Chokes (inductors) are versatile components used across various fields of electrical and electronic engineering. Their application ranges from voltage regulation in conventional transmission networks and reactive power compensation to load flow control and short-circuit current limitation in specialized applications.
As one of the leading choke manufacturers in Germany, we produce products perfectly suited to your use case. Whether single units or series production – with us, you benefit from maximum quality, flexibility, and reliability.
Chokes at a Glance: Function, Types, and Applications
Chokes, also known as inductors, are used to limit or suppress alternating currents. When current flows through them, they generate a magnetic field that induces a voltage opposing changes in current. Due to their inductance, chokes are particularly effective at limiting high frequencies and AC currents, while allowing DC to pass almost unaffected.
Types of Chokes
Chokes come in many forms. They can be roughly categorized into air-core inductors and inductors with a core. Air-core coils consist of spiral or wound wire and have low inductance, making them ideal for high-frequency applications due to the absence of core losses.
Chokes with cores include the following types:
- Ferrite Core Inductors: These use a ceramic ferrite core and have higher inductance than air-core variants. They offer good frequency stability.
- Iron Core Inductors: These employ iron powder or laminated iron cores, often coated with insulating materials to reduce losses. Suitable for low to medium frequencies. Higher frequencies may lead to increased eddy current and hysteresis losses.
- Toroidal Chokes: The wire is wound around a toroidal (ring-shaped) core. The magnetic field remains enclosed, ensuring high inductance with minimal losses and reduced electromagnetic interference.
- Common-Mode Chokes: These contain two windings on a shared core. They suppress common-mode noise without interfering with useful signals.
- Saturable Chokes: Specially designed to enter magnetic saturation under specific conditions. Their inductance is non-linear and decreases with increasing current – advantageous in control circuits and power supplies.
- Pot Core Inductors: These have a closed magnetic path around the winding, which increases inductance and minimizes stray field losses.
Each of these types has specific strengths and is suited for different applications.
Application Areas of Chokes
Chokes have a vast range of applications:
- In power supplies, they smooth out AC components for a stable DC supply.
- In transformers, they help stabilize voltage and mitigate current spikes, improving energy transfer.
- In EMI filters, they block or dampen unwanted high-frequency signals, reducing interference in electronic devices.
- In RF and communication technology, they are used in bandpass, low-pass, and high-pass filters to select or block signals.
- In antenna systems, they support impedance matching and interference reduction for optimal signal quality.
- In audio electronics, crossover networks use chokes to direct frequency ranges to specific speaker drivers and reduce noise.
- In automotive applications, chokes control DC motors and suppress EMI generated by motors.
- In induction heating systems, chokes regulate and control power output.
