High-Frequency Inductors & Chokes for Compact Power Systems
In today’s miniaturized and high-switching power environments, traditional inductors struggle with core losses, EMI emissions, and thermal inefficiencies. High-Frequency Chokes and Inductors solve these challenges by using advanced ferrite or iron powder cores with optimized foil or Enameled wire windings.
At Rishab Industries, we build high-frequency inductors tailored for SMPS (Switch Mode Power Supplies), solar MPPTs, battery chargers, EV power converters, and VFD-based systems. Our inductors are optimized for high-frequency operation (20kHz to 100kHz+), offering stable inductance, low EMI, and minimal thermal rise — all while maintaining a compact footprint.

Frequently Asked Questions (FAQs)
What are high-frequency chokes used for?
They're used to suppress EMI, filter switching ripple, and maintain clean power signals in SMPS, inverters, and EV systems.
What core material is best for high-frequency inductors?
Ferrite, iron powder, or nanocrystalline cores are preferred for low loss and thermal stability at high switching speeds.
Are these inductors available in shielded formats?
Yes. We offer both open frame and custom-shielded high-frequency chokes.
Can I use these in EV chargers or solar inverters?
Absolutely. They're ideal for filtering ripple and controlling EMI in high-frequency power conversion applications.
Do you provide EMI testing and thermal profiling?
Yes. All units are EMI-characterized, thermally validated, and built to international quality standards.
