Accessories

1. Overview

Board Mount Power Supply Accessories are components designed to facilitate the integration, protection, and optimization of power supply systems on printed circuit boards (PCBs). These accessories ensure reliable electrical connections, thermal management, and electromagnetic compatibility (EMC) in electronic devices. Their importance has grown with advancements in miniaturization, energy efficiency, and high-density computing systems.

2. Main Types and Functional Classification

TypeFunctional FeaturesApplication Examples
Power ConnectorsHigh-current transmission, polarization protection, vibration resistanceServers, industrial automation equipment
Heat SinksPassive cooling, thermal conduction optimization, airflow compatibilityPower amplifiers, LED lighting systems
Fuse HoldersOvercurrent protection, quick-disconnect design, resettable optionsAutomotive electronics, consumer appliances
EMI FiltersHigh-frequency noise suppression, differential/common-mode filteringMedical imaging equipment, communication infrastructure
Terminal BlocksWire-to-board connectivity, screw/clamp termination, color codingIndustrial control panels, HVAC systems

3. Structure and Composition

Typical configurations include:

  • Power Connectors: Made of phosphor bronze contacts with gold plating, thermoplastic insulation (e.g., LCP), and polarization keys
  • Heat Sinks: Extruded aluminum fins with matte black anodization, mounting clips or thermal adhesive pads
  • EMI Filters: Pi-network configuration with X/Y capacitors and common-mode chokes in polymer housing
  • Fuse Holders: Ceramic body with spring-loaded brass contacts and transparent polycarbonate covers

4. Key Technical Specifications

ParameterDescriptionImportance
Current RatingMaximum continuous operating current (1-50A range)Determines power capacity and trace sizing
Dielectric StrengthWithstand voltage (500V-5kV AC)Ensures electrical safety and insulation reliability
Operating TemperatureFunctional range (-55 C to +150 C)Affects performance in harsh environments
Thermal Resistance C/W rating for heat dissipation efficiencyDirectly impacts component lifespan
Insertion LossSignal attenuation at specific frequencies (for EMI filters)Measures noise suppression effectiveness

5. Application Fields

  • Telecommunications: 5G base stations, optical network units
  • Consumer Electronics: Gaming consoles, high-end laptops
  • Medical Devices: MRI scanners, patient monitoring systems
  • Automotive: EV charging systems, ADAS controllers
  • Industrial: CNC machines, PLC systems

6. Leading Manufacturers and Products

ManufacturerRepresentative ProductKey Features
TE ConnectivityPower Triple Lock connectors3-point contact system, 14A rating
CUI DevicesAMM series heat sinksMulti-finned aluminum design, 20-40 C temperature reduction
LittelfusePOWR-GARD fuse holdersHigh-rupture capacity, LED fault indication
SchurterFMA12 EMI filter12mm slim profile, 250VAC rating

7. Selection Recommendations

Key considerations:

  1. Electrical parameters matching system requirements (voltage/current derating)
  2. Environmental factors (operating temperature, humidity, vibration)
  3. Compliance with standards (UL/CSA/IEC certifications)
  4. PCB footprint compatibility and assembly method (SMT vs. through-hole)
  5. Total Cost of Ownership (lifetime reliability vs. initial cost)

Example: Selecting a 40A connector with 20% derating for a 32A power rail in an industrial motor drive.

8. Industry Trends

Emerging developments include:

  • Integration of smart sensors for real-time thermal monitoring
  • Adoption of advanced materials like graphene-enhanced thermal pads
  • Miniaturization driven by high-density PCB designs (0.8mm pitch connectors)
  • Increase in 48V board-level power distribution systems
  • RoHS-compliant, halogen-free polymer formulations
