High Consistency V18033H Ni-Zn Ferrite Core 1-500MHz Tested EMI Filter for CM DM Interference Suppression
V18033H Ni-Zn Ferrite Core for EMI Noise Suppression 1-500MHz
The V18033H is a toroidal gap‑free Ni‑Zn ferrite EMI suppression core manufactured by Shenzhen VIIP Electronics Co., Ltd, dedicated to EMC high‑frequency noise suppression. This high‑performance magnetic component effectively attenuates high‑frequency electromagnetic interference inside electronic circuits and wiring harnesses, fully complying with RoHS & REACH environmental requirements.
Impedance performance is validated by production sample test data, covering noise‑attenuation frequency range from 1 MHz to 500 MHz. Its closed toroidal magnetic‑path structure delivers stable broadband EMI filtering performance for cable harness and PCBA‑level EMC optimization. Full‑set test records and impedance‑frequency curve are documented in the official Rev.4.0 approval sheet (Doc No.6080024125) for engineering reference.

Frequently Asked Questions
Can I get free samples for H-series ferrite cores?
Yes, we can provide free H-series ferrite core samples for your performance testing and product evaluation.
What is your regular order requirement for ferrite cores?
Normally mass orders need to comply with our minimum package quantity requirement.
Does the free-sample policy allow small-quantity orders below MOQ for regular purchases?
Free samples are only intended for performance verification. While your first trial order can be negotiated, formal repeat orders must follow our minimum package quantity rule.
What certificates do H-series ferrite cores have?
Our H-series ferrite cores meet RoHS and REACH regulatory requirements.
What is the typical production lead-time for mass-production ferrite core orders?
Typical production lead-time ranges from 2 to 5 weeks, subject to order volume and stock status. Exact lead-time will be confirmed prior to your formal order placement.
Can you customize impedance, physical dimensions or material for H-type ferrite cores?
Customization service is available based on your detailed technical specifications. A dedicated MOQ will apply for all customized ferrite core projects.
Could you provide EMC technical support when I apply your ferrite cores in my projects?
Sure. Our in-house engineering team provides basic EMC technical consultation to assist you with noise-suppression design and circuit debugging work.
What applications are H-series ferrite cores suitable for?
H-series Ni-Zn ferrite cores are widely used for EMI / EMC noise suppression on PCBA traces, wiring harnesses, power cables, consumer electronics, power supplies and communication-related equipment.
