Pin to pin replaces WSH2818 precision resistor MFC2817

Precision resistors are indispensable important components in circuit design. With the rapid development of the electronics industry, there are more and more precision resistor applications. However, due to limited production capacity, VISHAY, a large company, has difficulties in supplying precision resistors. The customer knows that the basic delivery period has reached 50 weeks, and some products are even longer. In response to this situation, I recommend TT Electronics' high-power precision resistor MCF2817 to cope with this situation. It is recommended to use MFC2817 to replace VISHAY's WSH2818.

First look at the package size, 2817 and 2818 are basically the same, the PCB can be completely pin-pin replacement soldering, which is the most critical requirement for replacement resistors. Both of them have a power of 5W, which meets the requirements for testing large currents. The temperature drift of the MFC2817 is as low as 30PPM, which is better than WSH2818, which makes the circuit more accurate. The MCF2817 can completely replace the WSH2818 at -55 ° C - 155 ° C, 3 mΩ - 100 mΩ. Finally, the price of the MFC2817 is 20% cheaper than the WSH2818.

At present, Chinamax has fully represented TT Electronics' products. In view of the phenomenon that precision resistors are out of stock, MFC2817 is not out of stock, fast in supply and cheap, and is a good choice to replace WSH2818.
