RFHPDC Resistor Manufacturers: High Power Density Chip Resistors
Advertisement
This page details manufacturers and vendors specializing in HPDC (High Power Density Chip) Resistors.
Leading manufacturers of HPDC resistors include TT Electronics, Rohm Co., Ohmite Mfg. Co., Viking Tech Corporation, and KOA Corporation, among others.
What is an HPDC Resistor?
HPDC resistors are specifically designed for applications demanding high power handling capabilities, such as:
- Power Management
- Heating
- Actuator Controls
- Motor Drives
- Power Amplifiers
- Power Supplies
Compared to conventional chip resistors, HPDC resistors utilize materials with higher thermal conductivity, facilitating more efficient heat dissipation. They also feature large area terminations, enhancing thermal contact with the PCB surface.
Advantages of HPDC Resistors
HPDC resistors offer several key benefits:
- PCB Area Savings: Their high power density allows for smaller footprints compared to traditional high-power resistors.
- Enhanced Reliability: Improved thermal management leads to increased component lifespan and overall system reliability.
- Reduced Hotspots: Larger thermal contacts effectively restrict temperature rise in localized areas, preventing component damage.
- Improved Heat Transfer: Optimized design enhances heat transfer from the resistive element to the termination points.
