Through hole resistors are widely used in electronic engineering for the control of current, voltage or resistance. The MFP50SBRD52-2K03 is a dual-in-line through hole resistor package with a series rating of 50 watts. It is suitable for a variety of general purpose and switching regulator circuits.

The MFP50SBRD52-2K03 can be divided into two parts: the resistor body containing 50-watt wirewound resistors and the endguard containing one 90°C plastic-encapsulated terminal block.

The core construction of the MFP50SBRD52-2K03 is of open-air technology, providing secondary dissipation up to 130°C. This open-air design is cost-effective and provides higher current contacts than a closed construction. The MFP50SBRD52-2K03 features large perforations that enable the thermal transfer of heat to the environment and allow a higher current rating without the use of an external heatsink.

The 50-watt wirewound resistors in the MFP50SBRD52-2K03 have an impressive tolerances of ±0.02% and linearity that allows the adjustment of current over a broad range. The terminals are mounted on the resistor body and are rigidly oriented in order to maintain electrical connections when installation forces are incurred.

When the MFP50SBRD52-2K03 is used in the most usual application field of power supplies, it is able to provide a high-efficiency output at an exceptionally low power loss. The low power loss is created by the open-air construction of the device, which permits excellent cooling of the resistors.

The working principle of the MFP50SBRD52-2K03 is simple: when a certain voltage is applied across the terminals, current flows through the resistors. The resistor body controls and limits the current. The linearity of the resistor allows the current to be regulated within a wide range, enabling a precise output control in any application.

Thanks to its open-air design, the MFP50SBRD52-2K03 ensures excellent reliability in tough environmental conditions. The terminal block is completely encapsulated in plastic housings and the device is tested to UL 7721 and/or TÜV-certified standards. The terminals are securely fastened preventing any movement, and the MFP50SBRD52-2K03 offers an incredibly stable, highly precise and reliable performance.

The MFP50SBRD52-2K03 is a reliable, accurate, and cost-effective solution for a variety of general purpose, switching regulator and power supply applications. Thanks to its 50-watt rating, low power dissipation, and extensive safety features, it is the perfect device for controlling current, voltage, and resistance in demanding environments.
