Description

The 1K Ohm 5W Vertical (MPR) Wirewound Cement Power Resistor ±5% Tolerance is a high-performance resistor designed to handle moderate power dissipation with excellent resistance stability. Its robust wirewound construction and cement casing make it ideal for applications requiring precise resistance and reliable performance, even in demanding conditions.

Key Features:

• Resistance: 1,000 Ohms (1K Ohm), providing a precise and stable resistance value suitable for various applications, such as voltage dividers, power regulation, and current-limiting circuits. It helps in controlling the voltage and current levels in a wide range of electronic systems.
• Power Rating: 5 watts (5W), meaning the resistor can safely dissipate up to 5 watts of power without overheating. This makes it well-suited for medium-power applications where continuous or transient power dissipation is required.
• Tolerance: ±5% tolerance, meaning the actual resistance value will be within 5% of the nominal 1K Ohm value. This tolerance is suitable for most general-purpose applications where precise resistance values are important but perfect accuracy is not critical.
