Description

The 47 Ohm 5W Vertical (MPR) Wirewound Cement Power Resistor ±5% Tolerance is a high-performance resistor designed for medium to high-power applications where accurate resistance and efficient heat dissipation are essential. With a resistance value of 47 Ohms and a power rating of 5 watts, this vertical wirewound resistor is perfect for use in power circuits, current limiting, voltage regulation, and other demanding electronic applications.

Key Features:

• Resistance: 47 Ohms, providing stable and reliable resistance for use in applications such as current limiting, voltage dividers, and power regulation. The resistance value is carefully selected to ensure accurate performance in various electronic systems.
• Power Rating: 5 watts (5W), allowing the resistor to dissipate moderate power without overheating. This makes it suitable for circuits where reliable and consistent power handling is required over prolonged periods.
• Tolerance: ±5% tolerance, meaning the resistor's actual resistance will be within 5% of the nominal 47 Ohms. This tolerance level is commonly accepted in general-purpose applications where a precise resistance value is important but absolute accuracy is not critical.
• Wirewound Construction: The wirewound design offers superior accuracy and temperature stability compared to other resistor types. This construction is ideal for circuits where high power and high current are present, as wirewound resistors can handle these conditions better.
• Cement Body: The cement casing ensures efficient heat dissipation during operation, preventing overheating and extending the resistor’s lifespan. The cement material also provides physical protection from environmental stress, ensuring durability in harsh conditions.
• Vertical Mounting (MPR): The vertical (MPR) mounting style is perfect for designs where components need to be arranged vertically on a printed circuit board (PCB). The vertical mounting saves space and provides secure installation in confined areas or specific applications requiring vertical alignment.

Technical Specifications:
