Product Description
Ni-Zn H-Type Ferrite Core V18007H High Impedance EMC EMI Noise Suppression for PCBA Wiring Harness
Product Overview
The V18007H is an EMI suppression ferrite core manufactured by Shenzhen VIIP Electronics Co., Ltd, designed for EMC noise suppression. This high-performance component effectively suppresses high-frequency electromagnetic interference within electronic circuits and fully complies with RoHS & REACH environmental requirements.
Impedance performance is verified with 10-piece production sample test data, targeting noise attenuation across the 1-500 MHz frequency range. Its toroidal gap-free magnetic-path design provides stable broadband noise-reduction performance for cable harness and circuit-level EMC optimization.
Key Features
- Supports pre‑production sample evaluation to verify real‑world EMC filtering effect before bulk orders
- Mature manufacturing process, supports large‑volume OEM & ODM electronic manufacturing orders
- Suitable for signal line and low‑power power‑cable noise‑suppression scenarios
- Stable batch‑to‑batch consistency, avoids performance fluctuation among different production lots
- Ideal for compact power adapters, consumer electronics and data‑communication hardware

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.
