TT Electronics / Welwyn RC Series Metal Film Resistor 64.9kΩ ±0.1% 0.25W

The TT Electronics / Welwyn RC Series Metal Film Resistor delivers exceptional precision and reliability for demanding electronic circuits. Part of the esteemed RC Series, this component is engineered for applications where stable performance and tight tolerance are non-negotiable. With a precise resistance value of 64.9kΩ and an ultra-low tolerance of ±0.1%, it ensures accurate signal conditioning, voltage division, and biasing in sensitive analogue and digital systems.

Constructed using advanced metal film technology, this resistor offers superior performance characteristics compared to carbon film types. It features a low temperature coefficient of ±15ppm/°C, which minimises resistance drift across a wide operating temperature range from -55°C to +155°C. This stability is crucial for maintaining circuit integrity in environments subject to thermal fluctuations, such as in industrial controls, medical instrumentation, and precision measurement equipment.

Rated for 0.25W (250mW) of continuous power dissipation and a maximum working voltage of 200V, it is suitable for a broad spectrum of low to medium-power applications. The axial leaded package, with a compact form factor, is designed for straightforward through-hole PCB mounting, facilitating reliable and secure soldered connections. Its robust construction ensures long-term durability and consistent electrical characteristics.

This high-precision resistor is an ideal choice for critical roles in filter networks, feedback loops, calibration circuits, and any design requiring component-level accuracy. Its combination of metal film technology, tight tolerance, and wide temperature range makes it a dependable foundation for professional-grade electronics, prototyping, and repair work where component specification cannot be compromised.
