CRH1206F4K70P05Z 1206 4.7K 0.5W High Power Resistor — Technical Overview
Product Positioning
The CRH1206F4K70P05Z is a high power thick film chip resistor from Ever Ohms (TA-I Technology), housed in a standard 1206 package. It offers a nominal resistance of 4.7KΩ, a rated power of 0.5W (1/2W), a tolerance of ±1%, and a temperature coefficient of ±100PPM/°C. Maximum working voltage is 200V, maximum overload voltage is 400V, and the operating temperature range spans -55°C to +155°C.
The model designation follows Ever Ohms’ coding system: “CRH” identifies the high power thick film series, “1206” denotes the package size, “F” indicates ±1% tolerance, and “4K70” corresponds to the 4.7KΩ resistance value.The CRH series covers package sizes from 0402 to 2512, with power ratings ranging from 0.1W to 2W.
Technical Advantages
Doubled power density. Conventional 1206 thick film resistors are typically rated at 0.25W. The CRH1206F4K70P05Z achieves 0.5W through a thickened resistive film, optimized termination electrode structure, and a high-thermal-conductivity alumina substrate.This allows designers to double power handling capacity without changing the PCB footprint — a critical advantage in power management and motor drive circuits where board space is constrained.
Improved thermal management. The 0.5W rating provides greater headroom for continuous power dissipation in feedback divider and current sensing applications. The enhanced electrode heat dissipation structure shortens the thermal path from the resistor body to the PCB, helping to suppress localized hot spots.
Environmental compliance. The resistor operates across a -55°C to +155°C range and complies with EU RoHS Directive (2011/65/EU), free of REACH SVHC substances.
Applications
-
SMPS feedback dividers — 4.7KΩ is a common value in feedback networks; the 0.5W rating accommodates transient overloads and long-term aging effects.
-
Current sensing — maintains low temperature drift under continuous current flow in low-to-medium current detection circuits.
-
Industrial control boards — PLCs, inverters, and drive circuits requiring medium power handling in compact layouts.
-
LED drivers and appliance controls — suitable for LED constant-current drivers, fire alarm sensors, and dehumidifier control circuits.
