Automotive EMI Shielding
IATF 16949 certified components for ECUs, ADAS, EV systems, and infotainment. Direct from manufacturer.
Modern vehicles contain dozens of electronic control units, each requiring effective EMI management to meet automotive EMC standards. From engine management to advanced driver assistance, proper shielding ensures reliable operation and regulatory compliance.
POCONS provides automotive-grade EMI shielding components with full IATF 16949 traceability. Our components are qualified in production vehicles across major OEMs and Tier 1 suppliers.
EMI Shielding for ECUs
Electronic Control Units (ECUs) are the nervous system of modern vehicles. Each ECU requires board-level shielding to:
- Contain emissions from high-speed processors and switching regulators
- Protect sensitive inputs from ignition noise and motor drive interference
- Meet CISPR 25 radiated emission limits
The hard part is the switching regulator: a buck converter with ~1 ns edges produces broadband harmonics well past 300 MHz, and CISPR 25 scrutinizes the full 150 kHz–2.5 GHz span. A shield over the regulator and the clock oscillator — the two dominant offenders — usually moves a board from fail to pass more than edge-slowing or filtering alone.
Our two-piece shield assemblies allow rework access during development while providing 40-60 dB shielding effectiveness in production.

ADAS Radar & Sensor Shielding
Advanced Driver Assistance Systems (ADAS) combine radar, lidar, cameras, and ultrasonic sensors—each with unique EMI challenges:
- 77 GHz radar modules require precise RF isolation
- Camera processors need protection from high-frequency interference
- Sensor fusion units combine multiple signal types requiring multi-cavity shields
POCONS provides custom shield configurations for ADAS applications, including multi-cavity designs that isolate different functional blocks within a single assembly.

EV Power Electronics Shielding
Electric vehicle power electronics present unique EMI challenges due to high switching frequencies and power levels:
- Battery Management Systems (BMS) require isolation from high-voltage switching noise
- DC-DC converters generate significant conducted and radiated emissions
- Onboard chargers must meet strict EMC limits during charging cycles
Our components are qualified for high-temperature automotive environments and provide the shielding effectiveness needed for EV applications.
Recommended products:
Infotainment RF Isolation
Infotainment systems combine WiFi, Bluetooth, cellular, GPS, and digital radio—all requiring careful RF management:
- Multi-band antenna modules need isolation between transmit and receive paths
- Audio processors require protection from digital switching noise
- Display drivers generate high-frequency emissions that can interfere with radio reception
POCONS provides integrated shielding solutions that address the complex RF environment of modern infotainment systems.

US-Built Automotive Electronics That Use Board-Level Shields Like These
Vehicles assembled in North America — and the Tier-1 electronics built at US and Mexico-border plants — rely on board-level EMI shields to pass CISPR 25 and ISO 11452. These are the product classes where shields like POCONS' are designed in.
POCONS shield components are manufactured in Korea (IATF 16949) and stocked and supported domestically from San Diego. The end products above are US-built and use this class of board-level shielding; this page does not claim any specific named product contains POCONS parts.
US-built products & board-level shielding
Do US-built automotive radar and ADAS modules need board-level shielding?
Yes. Automotive electronics must meet CISPR 25 (radiated/conducted emissions) and ISO 11452 (immunity). Radar, infotainment, and cluster boards almost always use board-level shield cans to isolate RF and high-speed sections — the cheapest reliable path to passing EMC.
Are POCONS shields automotive-grade?
POCONS manufactures to IATF 16949 and can provide PPAP documentation for qualification programs. Components ship from domestic stock with US-based support.

Frequently Asked Questions
Are POCONS automotive EMI shields IATF 16949 certified?
Yes. Parts are produced under an IATF 16949 quality management system with APQP, PPAP, FMEA, SPC, and full traceability from raw material to finished part — the documentation automotive OEMs and Tier-1 suppliers require for qualification.
Can you shield ADAS radar, lidar, and camera modules?
Yes. We supply board-level shield cans and grounding for ADAS sensor and ECU modules, including multi-cavity cans that isolate the RF front-end from digital sections to prevent cross-coupling.
Do you support EV power-electronics and battery-management shielding?
Yes. EV inverters, on-board chargers, and BMS generate broadband EMI from high-dV/dt switching; we provide high-effectiveness board-level cans and grounding to help contain it and meet CISPR 25 / component-level EMC targets.
Where are the automotive parts manufactured?
They are precision-stamped at our IATF 16949–certified facility in Korea, with sales, stock, fast custom tooling, and engineering support from POCONS USA in San Diego. We do not represent the parts as US-made.
