TE Connectivity R Series Precision Through Hole Resistor, 249K, 0.25W, 500V

The TE Connectivity R Series Precision Through Hole Resistor is engineered for applications demanding exceptional long-term stability and reliability. This high-precision, 249kohm metal film resistor is constructed with a nickel-chrome alloy film evaporated onto a high thermal conductivity ceramic core, ensuring consistent performance under varying environmental conditions.

Featuring a tight tolerance of ± 0.1% and a low temperature coefficient of ±15ppm/°C, this component provides outstanding accuracy and minimal drift over time. Its robust axial leaded package is designed for through-hole mounting, offering secure and stable electrical connections. The component is protected by a multi-layer coating process, starting with a phenolic resin layer followed by three coats of epoxy resin, which safeguards against moisture, contaminants, and physical damage.

Key Advantages

• Superior Stability: Delivers excellent long-term stability under load and in severe environmental conditions, making it ideal for precision circuitry.
• Low Noise: Exhibits very low noise characteristics in both current and voltage, essential for sensitive analogue and measurement applications.
• Wide Operating Range: Capable of functioning reliably across an extensive temperature range from -65°C to +155°C.
• High Voltage Rating: With a 500V rating, it is suitable for circuits operating at higher voltages.

This 0.25W (250mW) resistor is a critical component for designers and engineers who require uncompromising precision and durability in their electronic designs.
