TE Connectivity Through Hole Resistor, 1K Ohm, 0.25W, 500V, ±0.1%

The TE Connectivity YR1B1K0CC is a high-precision, through-hole fixed resistor from the R Series, designed for circuits demanding exceptional accuracy and long-term stability. Its core is a thin film of nickel-chrome alloy deposited onto a high thermal conductivity ceramic element, providing excellent performance under load and in challenging environmental conditions. Metal end caps are force-fitted to the element before the spiralling process sets the precise resistance value, ensuring reliability and consistency.

Tinned copper lead wires are securely welded to these end caps, offering excellent solderability and electrical connection. The component is then protected by a robust coating: one layer of phenolic resin followed by three layers of epoxy resin, which safeguards against moisture, contaminants, and physical damage. This metal film construction results in very low noise characteristics and minimal current and voltage coefficients, making it ideal for sensitive analogue and measurement applications.

With a tight resistance tolerance of ±0.1% and a low temperature coefficient of ±15ppm/°C, this resistor maintains its specified performance across a wide operating temperature range from -65°C to 155°C. It is rated for 500V and has a power rating of 0.25W (250mW). Its axial leaded package is a standard, reliable format for through-hole PCB mounting.

This precision metal film resistor is particularly suitable for applications where long-term stability, accuracy, and low noise are critical, including test and measurement equipment, medical devices, precision power supplies, and audio circuitry. Its construction guarantees excellent stability under both load and severe environmental conditions, providing a dependable component for professional and industrial electronics.
