Key Features
- 75 Ω thick-film resistor in compact 0805 (2 mm × 0.5 mm) SMT package with ±5% tolerance for general-purpose circuit design
- 0.25 W power rating with ±200 ppm/°C temperature coefficient providing stable resistance across wide operating temperature ranges
- RoHS-compliant (JESD-609 e3) and REACH-compliant construction with lead-free terminations for use in consumer, industrial, and automotive electronics
Applications
The RK73B2ATTD750J is used in pull-up/pull-down networks, voltage dividers, current-limiting circuits, and signal conditioning stages in consumer electronics, industrial control boards, and communication equipment. Its 0805 form factor is compatible with high-speed automated SMT assembly, enabling efficient production at scale. The ±5% tolerance and 0.25 W rating make it a reliable general-purpose choice for non-precision analog and digital applications.

Frequently Asked Questions
What electrical specifications define the RK73B2ATTD750J for circuit design purposes?
The RK73B2ATTD750J is a 75 Ω thick-film resistor with ±5% tolerance, 0.25 W power rating, and ±200 ppm/°C temperature coefficient in an 0805 SMT package measuring 2 mm × 0.5 mm, suitable for general-purpose signal and power conditioning applications.
How does the 0805 package size of RK73B2ATTD750J affect board layout and assembly?
The 0805 package (2 mm long, 0.5 mm high) allows standard SMT pick-and-place assembly with typical pad spacing used on densely routed PCBs, accommodating 0.25 W dissipation without heat spreading concerns in most consumer and industrial PCB environments.
When should a designer choose RK73B2ATTD750J over a tighter-tolerance resistor for a voltage divider?
For voltage dividers where output precision requirements are looser than ±5%, such as biasing networks for general-purpose op-amps or LED current limiting at 5 V or 3.3 V rails, the RK73B2ATTD750J offers a cost-effective solution without paying for 1% or 0.1% precision resistor grades.
