Carbon Resistor 75Ω 0.5W Through Hole
The Carbon Resistor 75 Ω 0.5 W through-hole is a carbon-film fixed resistor in the CR series designed for general-purpose electronic use. In the CR family it corresponds to the 1/2 W power class and follows the standard cylindrical, axial-lead through-hole form factor. The component is constructed on a ceramic core with a deposited carbon film that establishes its 75-ohm resistance value, then coated with epoxy for insulation and mechanical protection.
As a 0.5 W carbon-film resistor it delivers stable resistance at room temperature and is intended for low-to-moderate power dissipation applications. Temperature coefficient and tolerance follow the CR series specifications (tolerances ±5% standard, ±2% option), and the part is tested for load-life, humidity and pulse overload performance according to the CR series test methods (JIS C 5202). It shows predictable drift characteristics within the specified limits after stress tests.
Because of its compact size (bulk dimensions for the 1/2 W CR type) and robust epoxy coating, this 75 Ω 0.5 W resistor is useful where a reliable, low-cost passive resistor is required. It is solderable per the supplier’s solderability and solder-heat recommendations and offers long service life (use life ≥10,000 hours under rated conditions).
