Power Accessories

Engineered thermal management heatsinks and high-attenuation conducted EMI filters designed to optimize reliability and EMC compliance for DC-DC converter modules.

High-Performance Thermal & EMC Power Accessories

Complementing our advanced DC-DC power conversion modules, NetPower supplies an array of specialized hardware accessories. Designed to meet strict industrial and automotive standard footprints (including 1/32nd, 1/8th, 1/4th, and 1/2 brick power modules), our accessories enable hardware engineers to satisfy thermal derating margins and stringent conducted electromagnetic interference (EMI) requirements with field-proven reliability.

Precision Heatsinks for Convection & Forced-Air Cooling

NetPower high-efficiency aluminum heatsinks are specifically formatted for DOSA-compliant and industry-standard brick DC-DC power modules. Available in multiple height profiles and fin orientations (transverse and longitudinal), these heatsinks optimize convection heat transfer and airflow pass-through, reducing junction temperature and extending power module operational lifespans in demanding high-ambient environments.

Conducted EMI Filters (PFT Series)

The NetPower PFT Series EMI filter modules are engineered to suppress differential-mode and common-mode conducted noise generated by high-frequency switching DC-DC power converters. Delivering ultra-high insertion loss across the regulatory spectrum, these compact filter blocks assist systems in meeting CISPR 22 / CISPR 32 Class B and FCC Part 15 Class B compliance limits seamlessly. Supporting operating input voltages up to 80V DC, PFT filters are ideal for 24V, 48V telecom, datacom, and industrial bus systems.

System Design & Thermal Integration Guidance

Selecting the ideal combination of heatsink height and EMI filter parameters depends heavily on system-level thermal dissipation requirements, target airflow (LFM), and environmental noise budgets. NetPower application engineering teams provide detailed 3D CAD models, thermal derating curves, and EMC test results to assist procurement teams and power architects during the design phase.

  • Precision CNC-machined baseplates for uniform thermal interface contact
  • Flame-retardant encapsulation materials meeting UL94 V-0 standards
  • Fully screened for harsh shock, vibration, and thermal cycling applications
