Tinned copper leads and a robust IP20 rating make it reliable and easy to integrate in through-hole PCB assemblies.

Versatile Power Supply Application

Ideal for electronic circuits, industrial power supplies, and EMI filtering, the ferrite toroidal choke operates with a rated voltage of 250V at 50-60 Hz and handles AC inputs up to 5A. Its size and weight are tailored for compact and efficient designs in both commercial and industrial environments.

FAQ's of Toroidal Choke:

Q: How is the ferrite toroidal choke installed in a circuit?

A: The toroidal choke is designed for through-hole mounting. Install it by inserting the tinned copper leads through the designated PCB holes and soldering them into place, ensuring strong mechanical and electrical connections.

Q: What benefits does this choke provide in power supply units?

A: It delivers robust electromagnetic interference (EMI) suppression and efficient signal filtering, which protect sensitive circuits and reduce unwanted noise in power supply units, enhancing overall performance and reliability.

Q: When should I use a toroidal ferrite choke with these specific characteristics?

A: This choke is optimal when your application demands high dielectric strength (1500V), low resistance (0.025 ), compact size, and reliable performance in environments featuring moisture or wide temperature variations-such as industrial power electronics and AC power supplies.

Q: Where is this toroidal choke commonly used?

A: It is widely used in electronic circuit designs, EMI filtering stages of industrial equipment, switch-mode power supplies, and various power electronics platforms requiring reliable AC current filtration.

Q: What process ensures its high moisture and dielectric resistance?

A: The choke's core and windings are encapsulated in epoxy, providing a tight seal against moisture ingress and improving electrical insulation for enhanced dielectric and environmental stability.

Q: How does its compact design benefit electronic assemblies?

A: Measuring just 20 x 8 x 8 mm and weighing 42 grams, the compact epoxy-coated design allows for integration into high-density PCB layouts and equipment where aerospace and board space are limited, without compromising performance.
