Product Description

TDK B82747S4423N020 is a 1.5 mH ferrite power line choke designed for efficient suppression of electromagnetic interference in power line applications. This choke features a ferrite core mounted on a polycarbonate base plate with pressboard spacer, fixed with PU compound that meets UL 94 V-0 flammability standards. With a rated maximum DC current of 42 A and a maximum DC resistance of just 2.6 mΩ, it offers high efficiency with low energy loss.

The device supports a maximum self-resonant frequency of 10 kHz and operates reliably in temperature ranges from -40°C up to 125°C. Its form factor includes a 72 mm diameter and length, with a height of 51 mm and depth of 72 mm, making it suitable for radial mounting on PCBs with 2.8 mm lead diameter termination style.

It complies with important industry standards including EN, RoHS, and UL, ensuring safety, quality, and environmental compliance. The B82747S series triple choke design provides approximately 1% stray inductance for symmetrical interference suppression, ideal for common-mode interference and switch-mode power applications found in industrial, construction, manufacturing, and electronics sectors.

Ferrite core on polycarbonate base plate ensures robustness and durability. Radial mount style supports wave soldering processes. Pressboard spacer and PU compound enhance mechanical stability and electrical insulation. Clearance of ≥3 mm and creepage distance of ≥4 mm for safe operation.

Suitable for high current and voltage power circuits up to 250 V AC. Applications include power line interference suppression and EMC compliant designs. Compliant with EN, RoHS, and UL approvals.

This power line choke is ideal for engineers and manufacturers designing reliable Power Line Filters and EMI suppression components. Explore more leading components and detailed technical documents in the Electronics Components category on EnvMart.
