Rotary resistance box for the DC circuit for use adjustable resistance, has a lower value of zero resistance, are all the most commonly used laboratory instruments for schools, factories and research units for electrical measurements and other experiments. When you test with the item, please make sure the voltage is under 5V, and the current is under 50 mA.The power is 0.25W When the proper use of resistance box to rotate the knob in each group, so that the contact resistance is stable and reliable.The maximum allowable current value of the resistance box in use should never exceed the specified. When only a small change in resistance, then wire to the "0" and another small indication terminal, can reduce the resistance inside the lead resistance. If you have any questions , please feel free to contact us ## Features - Made of high quality manganese copper wire, the resistance value does not change with the temperature, so that the resistance box is more accurate.With high quality metal film resistors, it is more expensive than carbon film resistor, but it has good stability, little influence on temperature and high accuracy Better use knob switch designed according to customer needs,When the proper use of resistance box to rotate the knob in each group, so that the contact resistance is stable and reliable.Resistor wirewound power storage kbpc3510 trimmer 100k ohm 1k potentiometer rheostat black box vehicle Type Power Tool Parts Usage Home DIY The maximum allowable current value of the resistance box in use should never exceed the specified. 1 resistor Wholesale box storag iron steam tool storage variable trimmer wirewound is_customized No Model Number Resistance Decade Box Wholesale power storage kbpc3510 shirt teacher Price metal jet plane tool home box for cloth iron case Unit Type piece Package Weight 0.46kg (1.01lb.)

While testing I could not get ANY of the resistance to measure under 10% of what I had set it at. Some were out as much as +-60%. ### ⭐ Cheap *by T***N on Reviewed in the United States on February 26, 2020* Tolerances where terrible. Potentiometers cheap and inconsistent resistance. Best part about this product was the case I can reuse for future project. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/151842741-gracemake-variable-decade-rotary-resistor-precision-dc-adjustable-resistance-box](https://www.desertcart.ph/products/151842741-gracemake-variable-decade-rotary-resistor-precision-dc-adjustable-resistance-box) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-05-26*
