1. Product Overview
Manufactured with high end 1K107B ferrite material, the V series
circular soft magnetic core is specially developed for high
frequency EMI elimination and common mode noise filtration. The
product boasts extremely high initial permeability of 80000 and
peak permeability up to 300000, with a saturation magnetic flux
density of 1250mT. It achieves excellent noise absorption effect
and stable magnetic transmission capacity during high frequency
operation.
The product features a Curie temperature of 570℃ and a broad
operating temperature range from minus 50℃ to 150℃. It can sustain
stable magnetic properties in low temperature high temperature and
drastic temperature fluctuation scenarios. With superior electrical
resistance and minimal eddy current loss, the core adopts precise
dimension control and stable batch production standards. It can
effectively eliminate high frequency common mode interference in
electronic circuits, optimize signal stability and lower
operational noise of electronic devices, helping finished products
meet standard EMC electromagnetic compatibility test criteria.
2. Application Scope & Purpose
This circular ferrite magnetic core is extensively applied in
common mode inductors, EMC filter components and high frequency
noise elimination circuits. It is widely compatible with switching
power supplies, power adapters, industrial power control units,
household electrical appliances, communication power units, vehicle
electronic systems and smart control equipment.
The core function of this magnetic core is to eliminate high
frequency common mode electromagnetic interference on power and
signal wires, filter random clutter generated during device
operation, and prevent signal distortion and equipment errors
caused by electromagnetic disturbance. It effectively enhances the
anti interference ability of electronic equipment and improves the
EMC test qualification rate of terminal products.
3. FAQ
Q1: How should I store ferrite magnetic rings?
A1: Store the products in dry indoor conditions. Keep away from strong
physical impact humid environment and corrosive gas to protect core
performance.
Q2: What is the difference between manganese zinc and nickel zinc
ferrite?
A2: Manganese zinc ferrite is suitable for low and medium frequency
common mode filtering scenarios while nickel zinc ferrite delivers
better performance for high frequency noise reduction applications.
Q3: Can you help me calculate inductance for wound common mode
choke?
A3: We can provide theoretical inductance reference values based on
core size material grade and winding turns. The actual inductance
data needs to be verified through real product testing.
Q4: Will vibration affect magnetic performance of ferrite rings?
A4: Standard finished magnetic cores can maintain stable magnetic
characteristics under normal vibration conditions. Only physical
cracks and structural damage will lead to performance degradation
or failure.
Q5: What should I do if EMC test still fails after using your
magnetic ring?
A5: You can optimize the overall performance by adjusting winding
quantities upgrading circuit layout configuring matched capacitors
or selecting higher grade magnetic core materials to achieve better
EMC suppression results.
