Electrical Characteristics & Design Notes
Standard 2512 chip resistors typically offer 1W rated power. The CRH series raises this to 2W through optimized ceramic substrate and resistive paste, doubling power density within the same footprint—enabling direct drop-in replacement without PCB redesign.
For a low resistance value of 4.7Ω, the actual operating boundary is governed by power rather than voltage:
Designers should carefully verify current margins in current-sensing and current-limiting applications.
Engineering recommendations:
-
Apply power derating above 70℃ ambient temperature
-
Keep continuous load below 1.4W (≈70% of rated power) for long-term stability
-
Increase pad copper area and use thermal vias on the PCB to reduce operating temperature
Typical Applications
This 2512 4.7R 2W resistor is primarily used in:
-
Power Management: Current sensing, voltage divider, dummy load in switching power supplies
-
Industrial Control: Current limiting and sampling in VFDs and servo drives
-
Automotive Electronics: Balancing resistors and protection circuits in BMS and on-board chargers
-
Consumer & Communication: LED drivers, power adapters, networking equipment
Its wide operating temperature range (-55℃ ~ +155℃) meets industrial-grade requirements. For stringent automotive applications, confirm the specific AEC-Q200 certification status with your supplier.
